[ Upstream commit e8123311cf06d7dae71e8c5fe78e0510d20cd30b ]
When the driver fails to call the dma_set_mask(), the driver will get
the following splat:
[ 55.853884] BUG: KASAN: use-after-free in __process_removed_driver+0x3c/0x240
[ 55.854486] Read of size 8 at addr ffff88810de60408 by task modprobe/590

[ 55.860327] __process_removed_driver+0x3c/0x240
[ 55.861347] bus_for_each_dev+0x102/0x160
[ 55.861681] i2c_del_driver+0x2f/0x50
This is because the driver has initialized the i2c related resources
in cx23885_dev_setup() but not released them in error handling, fix this
bug by modifying the error path that jumps after failing to call the
dma_set_mask().

commit fc84e1f941b91221092da5b3102ec82da24c5673 upstream.
In bfq_insert_request() we unlock bfqd->lock only to call
trace_block_rq_insert() and then lock bfqd->lock again. This is really
pointless since tracing is disabled if we really care about performance
and even if the tracepoint is enabled, it is a quick call.

[ Upstream commit c7666240ec76422cb7546bd07cc8ae80dc0ccdd2 ]
The ARASAN MMC controller on Keystone 3 class of devices need the SDCD
line to be connected for proper functioning. Similar to the issue pointed
out in sdhci-of-arasan.c driver, commit 3794c542641f ("mmc:
sdhci-of-arasan: Set controller to test mode when no CD bit").
In cases where this can't be connected, add a quirk to force the
controller into test mode and set the TESTCD bit. Use the flag
"ti,fails-without-test-cd", to implement this above quirk when required.

From: Tali Perry <[email protected]>
[ Upstream commit e5222d408de2a88e6b206c38217b48d092184553 ]
On some platforms in rare cases (1 to 100,000 transactions),
the i2c gets a spurious interrupt which means that we enter an interrupt
but in the interrupt handler we don't find any status bit that points to
the reason we got this interrupt.
This may be a case of a rare HW issue or signal integrity issue that is
still under investigation.
In order to overcome this we are doing the following:
1. Disable incoming interrupts in master mode only when slave mode is not
enabled.
2. Clear end of busy (EOB) after every interrupt.
3. Clear other status bits (just in case since we found them cleared)
4. Return correct status during the interrupt that will finish the
transaction.
On next xmit transaction if the bus is still busy the master will issue a
recovery process before issuing the new transaction.
Fixes: 56a1485b102e ("i2c: npcm7xx: Add Nuvoton NPCM I2C controller driver")

In preparation to a following commit, add clang-format on and
clang-format off stanzas around constant definitions. This enables to
keep aligned values, which is much more readable than packed

[ Upstream commit c3e3ca05dae37f8f74bb80358efd540911cbc2c8 ]
Since the introduction of regulator->enable_count, a driver that did
an exclusive get on an already-enabled regulator would end up with
enable_count initialized to 0 but rdev->use_count initialized to 1.
With that starting point the regulator is effectively stuck enabled,
because if the driver attempted to disable it it would fail the
enable_count underflow check in _regulator_handle_consumer_disable().
The EXCLUSIVE_GET path in _regulator_get() now initializes
enable_count along with rdev->use_count so that the regulator can be
disabled without underflowing the former.

From: Johannes Berg <[email protected]>
commit 57ae0b67b747031bc41fb44643aa5344ab58607e upstream.
The previous fix here was only partially correct, it did
result in returning a proper error value in case of error,
but it also clobbered the pid that we need to return from
this function (not just zero for success).
As a result, it returned 0 here, but later this is treated
as a pid and used to kill the process, but since it's now
0 we kill(0, SIGKILL), which makes UML kill itself rather
than just the helper thread.
Fix that and make it more obvious by using a separate
variable for the pid.

commit 3880f2b816a7e4ca889b7e8a42e6c62c5706ed36 upstream.
Two problems:
1. ntfs3_setattr can't truncate preallocated space;
2. if allocated fragment "cross" valid size, then fragment splits into two parts:
- normal part;
- unwritten part (here we must return FIEMAP_EXTENT_LAST).
Before this commit we returned FIEMAP_EXTENT_LAST for whole fragment.

From: Eric W. Biederman <[email protected]>
commit 4a3d2717d140401df7501a95e454180831a0c5af upstream.
xtensa is the last user of the PT_SINGLESTEP flag. Changing tsk->ptrace in
user_enable_single_step and user_disable_single_step without locking could
potentiallly cause problems.
So use a thread info flag instead of a flag in tsk->ptrace. Use TIF_SINGLESTEP
that xtensa already had defined but unused.
Remove the definitions of PT_SINGLESTEP and PT_BLOCKSTEP as they have no more users.

mdp5_get_global_state runs the risk of hitting a -EDEADLK when acquiring
the modeset lock, but currently mdp5_pipe_release doesn't check for if
an error is returned. Because of this, there is a possibility of
mdp5_pipe_release hitting a NULL dereference error.
To avoid this, let's have mdp5_pipe_release check if
mdp5_get_global_state returns an error and propogate that error.
Changes since v1:
- Separated declaration and initialization of *new_state to avoid
compiler warning
- Fixed some spelling mistakes in commit message
Changes since v2:
- Return 0 in case where hwpipe is NULL as this is considered normal
behavior
- Added 2nd patch in series to fix a similar NULL dereference issue in
mdp5_mixer_release

[ Upstream commit 2679a83731d51a744657f718fc02c3b077e47562 ]
When we use raw_spin_rq_lock() to acquire the rq lock and have to
update the rq clock while holding the lock, the kernel may issue
a WARN_DOUBLE_CLOCK warning.
Since we directly use raw_spin_rq_lock() to acquire rq lock instead of
rq_lock(), there is no corresponding change to rq->clock_update_flags.
In particular, we have obtained the rq lock of other CPUs, the
rq->clock_update_flags of this CPU may be RQCF_UPDATED at this time, and
then calling update_rq_clock() will trigger the WARN_DOUBLE_CLOCK warning.
So we need to clear RQCF_UPDATED of rq->clock_update_flags to avoid
the WARN_DOUBLE_CLOCK warning.
For the sched_rt_period_timer() and migrate_task_rq_dl() cases
we simply replace raw_spin_rq_lock()/raw_spin_rq_unlock() with
rq_lock()/rq_unlock().
For the {pull,push}_{rt,dl}_task() cases, we add the
double_rq_clock_clear_update() function to clear RQCF_UPDATED of
rq->clock_update_flags, and call double_rq_clock_clear_update()
before double_lock_balance()/double_rq_lock() returns to avoid the
WARN_DOUBLE_CLOCK warning.

Steps to reproduce:
1. Enable CONFIG_SCHED_DEBUG when compiling the kernel
2. echo 1 > /sys/kernel/debug/clear_warn_once
echo "WARN_DOUBLE_CLOCK" > /sys/kernel/debug/sched/features
echo "NO_RT_PUSH_IPI" > /sys/kernel/debug/sched/features
3. Run some rt/dl tasks that periodically work and sleep, e.g.
Create 2*n rt or dl (90% running) tasks via rt-app (on a system
with n CPUs), and Dietmar Eggemann reports Call Trace 4 when running
on PREEMPT_RT kernel.

[ Upstream commit fd5e363eac77ef81542db77ddad0559fa0f9204e ]
Upon nfsd shutdown any pending DRC cache is freed. DRC cache use is
tracked via a percpu counter. In the current code the percpu counter
is destroyed before. If any pending cache is still present,
percpu_counter_add is called with a percpu counter==NULL. This causes
a kernel crash.
The solution is to destroy the percpu counter after the cache is freed.

[ Upstream commit bb9b9eb0ae2e9d3f6036f0ad907c3a83dcd43485 ]
When tcmu_vma_fault() gets a page successfully, before the current context
completes page fault procedure, find_free_blocks() may run and call
unmap_mapping_range() to unmap the page. Assume that when
find_free_blocks() initially completes and the previous page fault
procedure starts to run again and completes, then one truncated page has
been mapped to userspace. But note that tcmu_vma_fault() has gotten a
refcount for the page so any other subsystem won't be able to use the page
unless the userspace address is unmapped later.
If another command subsequently runs and needs to extend dbi_thresh it may
reuse the corresponding slot for the previous page in data_bitmap. Then
though we'll allocate new page for this slot in data_area, no page fault
will happen because we have a valid map and the real request's data will be
lost.
Filesystem implementations will also run into this issue but they usually
lock the page when vm_operations_struct->fault gets a page and unlock the
page after finish_fault() completes. For truncate filesystems lock pages in
truncate_inode_pages() to protect against racing wrt. page faults.
To fix this possible data corruption scenario we can apply a method similar
to the filesystems. For pages that are to be freed, tcmu_blocks_release()
locks and unlocks. Make tcmu_vma_fault() also lock found page under
cmdr_lock. At the same time, since tcmu_vma_fault() gets an extra page
refcount, tcmu_blocks_release() won't free pages if pages are in page fault
procedure, which means it is safe to call tcmu_blocks_release() before
unmap_mapping_range().
With these changes tcmu_blocks_release() will wait for all page faults to
be completed before calling unmap_mapping_range(). And later, if
unmap_mapping_range() is called, it will ensure stale mappings are removed.

[ Upstream commit 4288caed9a6319b766dc0adf605c7b401180db34 ]
Unlike on R-Car Gen3 SoCs, setting a bit to zero in a GPIO / Peripheral
Function Select Register (GPSRn) on R-Car V3U is not always sufficient
to configure a pin for GPIO. For I2C-capable pins, the I2C function
must also be explicitly disabled in the corresponding Module Select
Register (MODSELn).
Add the missing FN_SEL_I2Ci_0 function enums to the pinmux_data[] array
by temporarily overriding the GP_2_j_FN function enum to expand to two
enums: the original GP_2_j_FN enum to configure the GSPR register bits,
and the missing FN_SEL_I2Ci_0 enum to configure the MODSEL register
bits.

[ Upstream commit c127d130f6d59fa81701f6b04023cf7cd1972fb3 ]
In init_winctx_regs(), __pa() is called on winctx->rx_fifo and this
function is called to initialize registers for receive and fault
windows. But the real address is passed in winctx->rx_fifo for
receive windows and the virtual address for fault windows which
causes errors with DEBUG_VIRTUAL enabled. Fixes this issue by
assigning only real address to rx_fifo in vas_rx_win_attr struct
for both receive and fault windows.

commit e95113ed4d428219e3395044e29f5713fc446720 upstream.
If size of file was reduced, we still kept allocated blocks.
This commit makes ntfs3 work as other fs like btrfs.

Commit 587f03deb69b caused pnfs_update_layout() to stop returning ENOMEM
when the memory allocation fails, and hence causes it to fall back to
trying to do I/O through the MDS. There is no guarantee that this will
fare any better. If we're failing the pNFS layout allocation, then we
should just redirty the page and retry later.

commit 3bc5e683c67d94bd839a1da2e796c15847b51b69 upstream.
When bfqq is shared by multiple processes it can happen that one of the
processes gets moved to a different cgroup (or just starts submitting IO
for different cgroup). In case that happens we need to split the merged
bfqq as otherwise we will have IO for multiple cgroups in one bfqq and
we will just account IO time to wrong entities etc.
Similarly if the bfqq is scheduled to merge with another bfqq but the
merge didn't happen yet, cancel the merge as it need not be valid
anymore.

From: Guenter Roeck <[email protected]>
[ Upstream commit abae018a03821be2b65c01ebe2bef06fd7d85a4c ]
Calling hwmon_device_register_with_info() with NULL dev and/or chip
information parameters is an ABI abuse and not a real conversion to
the new API. Also, the code creates sysfs attributes _after_ creating
the hwmon device, which is racy and unsupported to start with. On top
of that, the removal code tries to remove the name attribute which is
owned by the hwmon core.
Use hwmon_device_register_with_groups() to register the hwmon device
instead.
In the future, the hwmon subsystem will reject calls to
hwmon_device_register_with_info with NULL dev or chip/info parameters.
Without this patch, the hwmon device will fail to register.

[ Upstream commit 7ab889f09dfa70e8097ec1b9186fd228124112cb ]
The ref builder only provided references that are marked as valid in the
dpb. Thus the current implementation of dpb_valid would always set the
flag to 1. This is not representing missing frames (this is called
'non-existing' pictures in the spec). In some context, these non-existing
pictures still need to occupy a slot in the reference list according to
the spec.

[ Upstream commit ca75f6f7c6f89365e40f10f641b15981b1f07c31 ]
There is a possibility for mdp5_get_global_state to return
-EDEADLK when acquiring the modeset lock, but currently global_state in
mdp5_mixer_release doesn't check for if an error is returned.
To avoid a NULL dereference error, let's have mdp5_mixer_release
check if an error is returned and propagate that error.

Since commit 23127296889f ("sched/fair: Update scale invariance of PELT")
change to use rq_clock_pelt() instead of rq_clock_task(), we should also
use rq_clock_pelt() for throttled_clock_task_time and throttled_clock_task
accounting to get correct cfs_rq_clock_pelt() of throttled cfs_rq. And
rename throttled_clock_task(_time) to be clock_pelt rather than clock_task.

From: Sven Schnelle <[email protected]>
commit 5ace65ebb5ce9fe1cc8fdbdd97079fb566ef0ea4 upstream.
clock_delta is declared as unsigned long in various places. However,
the clock sync delta can be negative. This would add a huge positive
offset in clock_sync_global where clock_delta is added to clk.eitod
which is a 72 bit integer. Declare it as signed long to fix this.

versus the mask, as checking with the YCYC value may not include
some bits that may be set.
It is correct and safe to check the whole mask.

commit d63c00ea435a5352f486c259665a4ced60399421 upstream.
Otherwise nonaligned fstrim calls will works inconveniently for iterative
scanners, for example:
// trim [0,16MB] for group-1, but mark full group as trimmed
fstrim -o $((1024*1024*128)) -l $((1024*1024*16)) ./m
// handle [16MB,16MB] for group-1, do nothing because group already has the flag.
fstrim -o $((1024*1024*144)) -l $((1024*1024*16)) ./m

[ Upstream commit 5cebb40bc9554aafcc492431181f43c6231b0459 ]
PTP one step sync packets cannot have CSUM padding and insertion in
SW since time stamp is inserted on the fly by HW.
In addition, ptp4l version 3.0 and above report an error when skb
timestamps are reported for packets that not processed for TX TS
after transmission.
Add a helper to identify PTP one step sync and fix the above two
errors. Add a common mask for PTP header flag field "twoStepflag".
Also reset ptp OSS bit when one step is not selected.
Fixes: ab91f0a9b5f4 ("net: macb: Add hardware PTP support")

From: Zhengjun Xing <[email protected]>
[ Upstream commit f4df0dbbe62ee8e4405a57b27ccd54393971c773 ]
In the origin code, when "ExtSel" is 1, the eventcode will change to
"eventcode |= 1 << 21”. For event “UNC_Q_RxL_CREDITS_CONSUMED_VN0.DRS",
its "ExtSel" is "1", its eventcode will change from 0x1E to 0x20001E,
but in fact the eventcode should <=0x1FF, so this will cause the parse
fail:
# perf stat -e "UNC_Q_RxL_CREDITS_CONSUMED_VN0.DRS" -a sleep 0.1
event syntax error: '.._RxL_CREDITS_CONSUMED_VN0.DRS'
\___ value too big for format, maximum is 511
On the perf kernel side, the kernel assumes the valid bits are continuous.
It will adjust the 0x100 (bit 8 for perf tool) to bit 21 in HW.
DEFINE_UNCORE_FORMAT_ATTR(event_ext, event, "config:0-7,21");
So the perf tool follows the kernel side and just set bit8 other than bit21.

outstanding credits must be initialized to 0,
because it means the sum of credits consumed by
in-flight requests.
And outstanding credits must be compared with
total credits in smb2_validate_credit_charge(),
because total credits are the sum of credits

This patch fix the following error,

[ Upstream commit 4ba68c5192554876bd8c3afd904e3064d2915341 ]
If at the end of rxrpc sendmsg() or rxrpc_kernel_send_data() the call that
was being given data was aborted remotely or otherwise failed, return an
error rather than returning the amount of data buffered for transmission.
The call (presumably) did not complete, so there's not much point
continuing with it. AF_RXRPC considers it "complete" and so will be
unwilling to do anything else with it - and won't send a notification for
it, deeming the return from sendmsg sufficient.
Not returning an error causes afs to incorrectly handle a StoreData
operation that gets interrupted by a change of address due to NAT
reconfiguration.
This doesn't normally affect most operations since their request parameters
tend to fit into a single UDP packet and afs_make_call() returns before the
server responds; StoreData is different as it involves transmission of a
lot of data.
This can be triggered on a client by doing something like:
dd if=/dev/zero of=/afs/example.com/foo bs=1M count=512
at one prompt, and then changing the network address at another prompt,
e.g.:
ifconfig enp6s0 inet 192.168.6.2 && route add 192.168.6.1 dev enp6s0
Tracing packets on an Auristor fileserver looks something like:
192.168.6.1 -> 192.168.6.3 RX 107 ACK Idle Seq: 0 Call: 4 Source Port: 7000 Destination Port: 7001
192.168.6.3 -> 192.168.6.1 AFS (RX) 1482 FS Request: Unknown(64538) (64538)

192.168.6.2 -> 192.168.6.1 AFS (RX) 1482 FS Request: Unknown(0) (0)

192.168.6.1 -> 192.168.6.2 RX 74 ABORT Seq: 29321 Call: 4 Source Port: 7000 Destination Port: 7001
The Auristor fileserver logs code -453 (RXGEN_SS_UNMARSHAL), but the abort
code received by kafs is -5 (RX_PROTOCOL_ERROR) as the rx layer sees the
condition and generates an abort first and the unmarshal error is a
consequence of that at the application layer.

intel_hid_dsm_fn_mask is a bit mask containing one bit for each function

accordingly, which was missed in commit 97ab4516205e ("platform/x86:

Debugging showed that the rate statistics for the first four rates where
stored in the MINSTREL_CCK_GROUP instead of the MINSTREL_OFDM_GROUP because
in minstrel_ht_get_stats() the supported check was not honoured as done in
various other places, e.g net/mac80211/rc80211_minstrel_ht_debugfs.c:

commit bbe832b9db2e1ad21522f8f0bf02775fff8a0e0e upstream.
At present, pages not in the target zone are added to cc->migratepages
list in isolate_migratepages_block(). As a result, pages may migrate
between nodes unintentionally.
This would be a serious problem for older kernels without commit
a984226f457f849e ("mm: memcontrol: remove the pgdata parameter of
mem_cgroup_page_lruvec"), because it can corrupt the lru list by
handling pages in list without holding proper lru_lock.
Avoid returning a pfn outside the target zone in the case that it is
not aligned with a pageblock boundary. Otherwise
isolate_migratepages_block() will handle pages not in the target zone.

From: Sean Christopherson <[email protected]>
commit 1aa0e8b144b6474c4914439d232d15bfe883636b upstream.
Add a config option to guard (future) usage of asm_volatile_goto() that
includes "tied outputs", i.e. "+" constraints that specify both an input
and output parameter. clang-13 has a bug[1] that causes compilation of
such inline asm to fail, and KVM wants to use a "+m" constraint to
implement a uaccess form of CMPXCHG[2]. E.g. the test code fails with
<stdin>:1:29: error: invalid operand in inline asm: '.long (${1:l}) - .'
int foo(int *x) { asm goto (".long (%l[bar]) - .\n": "+m"(*x) ::: bar); return *x; bar: return 0; }
^
<stdin>:1:29: error: unknown token in expression
<inline asm>:1:9: note: instantiated into assembly here
.long () - .
^
2 errors generated.
on clang-13, but passes on gcc (with appropriate asm goto support). The
bug is fixed in clang-14, but won't be backported to clang-13 as the
changes are too invasive/risky.
gcc also had a similar bug[3], fixed in gcc-11, where gcc failed to
account for its behavior of assigning two numbers to tied outputs (one
for input, one for output) when evaluating symbolic references.

[ Upstream commit c4040212bc97d16040712a410335f93bc94d2262 ]
If the slang lib is not installed on the system, perf c2c tool disables TUI
mode and roll back to use stdio mode; but the flag 'c2c.use_stdio' is
missed to set true and thus it wrongly applies UI quirks in the function
ui_quirks().
This commit forces to use stdio interface if slang is not supported, and
it can avoid to apply the UI quirks and show the correct metric header.

From: Yonghong Song <[email protected]>
[ Upstream commit 4050764cbaa25760aab40857f723393c07898474 ]
Latest llvm-project upstream had a change of behavior
related to qualifiers on function return type ([1]).
This caused selftests btf_dump/btf_dump failure.
The following example shows what changed.
$ cat t.c
typedef const char * const (* const (* const fn_ptr_arr2_t[5])())(char * (*)(int));
struct t {
int a;
fn_ptr_arr2_t l;
};
int foo(struct t *arg) {
return arg->a;
}
Compiled with latest upstream llvm15,
$ clang -O2 -g -target bpf -S -emit-llvm t.c
The related generated debuginfo IR looks like:
!16 = !DIDerivedType(tag: DW_TAG_typedef, name: "fn_ptr_arr2_t", file: !1, line: 1, baseType: !17)
!17 = !DICompositeType(tag: DW_TAG_array_type, baseType: !18, size: 320, elements: !32)
!18 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !19)
!19 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !20, size: 64)
!20 = !DISubroutineType(types: !21)
!21 = !{!22, null}
!22 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !23, size: 64)
!23 = !DISubroutineType(types: !24)
!24 = !{!25, !28}
!25 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !26, size: 64)
!26 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !27)
!27 = !DIBasicType(name: "char", size: 8, encoding: DW_ATE_signed_char)
You can see two intermediate const qualifier to pointer are dropped in debuginfo IR.
With llvm14, we have following debuginfo IR:
!16 = !DIDerivedType(tag: DW_TAG_typedef, name: "fn_ptr_arr2_t", file: !1, line: 1, baseType: !17)
!17 = !DICompositeType(tag: DW_TAG_array_type, baseType: !18, size: 320, elements: !34)
!18 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !19)
!19 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !20, size: 64)
!20 = !DISubroutineType(types: !21)
!21 = !{!22, null}
!22 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !23)
!23 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !24, size: 64)
!24 = !DISubroutineType(types: !25)
!25 = !{!26, !30}
!26 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !27)
!27 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !28, size: 64)
!28 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !29)
!29 = !DIBasicType(name: "char", size: 8, encoding: DW_ATE_signed_char)
All const qualifiers are preserved.
To adapt the selftest to both old and new llvm, this patch removed
the intermediate const qualifier in const-to-ptr types, to make the
test succeed again.

From: Laurent Vivier <[email protected]>
commit 2e2ac4a3327479f7e2744cdd88a5c823f2057bad upstream.
The goldfish TTY device was clearly defined as having little-endian
registers, but the switch to __raw_{read,write}l(() broke its driver
when running on big-endian kernels (if anyone ever tried this).
The m68k qemu implementation got this wrong, and assumed native-endian
registers. While this is a bug in qemu, it is probably impossible to
fix that since there is no way of knowing which other operating systems
have started relying on that bug over the years.
Hence revert commit da31de35cd2f ("tty: goldfish: use
__raw_writel()/__raw_readl()", and define gf_ioread32()/gf_iowrite32()
to be able to use accessors defined by the architecture.

[ Upstream commit a91ee0e9fca9d7501286cfbced9b30a33e52740a ]
The sysfs sriov_numvfs_store() path acquires the device lock before the
config space access lock:
sriov_numvfs_store
device_lock # A (1) acquire device lock
sriov_configure
vfio_pci_sriov_configure # (for example)
vfio_pci_core_sriov_configure
pci_disable_sriov
sriov_disable
pci_cfg_access_lock
pci_wait_cfg # B (4) wait for dev->block_cfg_access == 0
Previously, pci_dev_lock() acquired the config space access lock before the
device lock:
pci_dev_lock
pci_cfg_access_lock
dev->block_cfg_access = 1 # B (2) set dev->block_cfg_access = 1
device_lock # A (3) wait for device lock
Any path that uses pci_dev_lock(), e.g., pci_reset_function(), may
deadlock with sriov_numvfs_store() if the operations occur in the sequence
(1) (2) (3) (4).
Avoid the deadlock by reversing the order in pci_dev_lock() so it acquires
the device lock before the config space access lock, the same as the
sriov_numvfs_store() path.

[ Upstream commit 66f862563ed68717dfd84e808ca12705ed275ced ]
When using an external PHY connected using RGMII to mt7531 port 5, the
PHY can be used to used support 1000BASE-X connections. Moreover, if
1000BASE-T is supported, then we should allow 1000BASE-X as well, since
which are supported is a property of the PHY.
Therefore, it makes no sense to exclude this from the linkmodes when
1000BASE-T is supported.

[ Upstream commit 622d9b5577f19a6472db21df042fea8f5fefe244 ]
In the genpd governor we walk the list of child-domains to take into
account their next_wakeup. If the child-domain itself, doesn't have a
governor assigned to it, we can end up using the next_wakeup value before
it has been properly initialized. To prevent a possible incorrect behaviour
in the governor, let's initialize next_wakeup to KTIME_MAX.

ath11k_peer_find_by_addr states via lockdep that ab->base_lock must be
held when calling that function in order to protect the list. All
callers except ath11k_mac_op_unassign_vif_chanctx have that lock
acquired when calling ath11k_peer_find_by_addr. That lock is also not
transitively held by a path towards ath11k_mac_op_unassign_vif_chanctx.
The solution is to acquire the lock when calling
ath11k_peer_find_by_addr inside ath11k_mac_op_unassign_vif_chanctx.
I am currently working on a static analyser to detect missing locks and
this was a reported case. I manually verified the report by looking at
the code, but I do not have real hardware so this is compile tested
only.

From: Xiaomeng Tong <[email protected]>
commit 8b9ad480bd1dd25f4ff4854af5685fa334a2f57a upstream.
The bug is here:
if (!iommu || iommu->dev->of_node != spec->np) {
The list iterator value 'iommu' will *always* be set and non-NULL by
list_for_each_entry(), so it is incorrect to assume that the iterator
value will be NULL if the list is empty or no element is found (in fact,
it will point to a invalid structure object containing HEAD).
To fix the bug, use a new value 'iter' as the list iterator, while use
the old value 'iommu' as a dedicated variable to point to the found one,
and remove the unneeded check for 'iommu->dev->of_node != spec->np'
outside the loop.

[ Upstream commit fc4ef9d5724973193bfa5ebed181dba6de3a56db ]
There is a slab-out-of-bounds Write bug in hid-bigbenff driver.
The problem is the driver assumes the device must have an input but
some malicious devices violate this assumption.
Fix this by checking hid_device's input is non-empty before its usage.

From: Theodore Ts'o <[email protected]>
commit c878bea3c9d724ddfa05a813f30de3d25a0ba83f upstream.
The EXT4_FC_REPLAY bit in sbi->s_mount_state is used to indicate that
we are in the middle of replay the fast commit journal. This was
actually a mistake, since the sbi->s_mount_info is initialized from
es->s_state. Arguably s_mount_state is misleadingly named, but the
name is historical --- s_mount_state and s_state dates back to ext2.
What should have been used is the ext4_{set,clear,test}_mount_flag()
inline functions, which sets EXT4_MF_* bits in sbi->s_mount_flags.
The problem with using EXT4_FC_REPLAY is that a maliciously corrupted
superblock could result in EXT4_FC_REPLAY getting set in
s_mount_state. This bypasses some sanity checks, and this can trigger
a BUG() in ext4_es_cache_extent(). As a easy-to-backport-fix, filter
out the EXT4_FC_REPLAY bit for now. We should eventually transition
away from EXT4_FC_REPLAY to something like EXT4_MF_REPLAY.

This shouldn't be a problem in practice since until we've actually
taken over the console there's nothing we've registered with the
console/vt subsystem, so the exit/unbind path that check this can't
do the wrong thing. But it's confusing, so fix it by moving it a tad
later.

2.35.1
From: Stephen Boyd <[email protected]>
commit 2f3724930eb4bba74f7d10bc3bef5bb22dd323df upstream.
The IPA BCM resource ("IP0") on sc7180 was moved to the clk-rpmh driver
in commit bcd63d222b60 ("clk: qcom: rpmh: Add IPA clock for SC7180") and
modeled as a clk, but this interconnect driver still had it modeled as
an interconnect. This was mostly OK because nobody used the interconnect
definition, until the interconnect framework started dropping bandwidth
requests on interconnects that aren't used via the sync_state callback
in commit 7d3b0b0d8184 ("interconnect: qcom: Use icc_sync_state"). Once
that patch was applied the IP0 resource was going to be controlled from
two places, the clk framework and the interconnect framework.
Even then, things were probably going to be OK, because commit
b95b668eaaa2 ("interconnect: qcom: icc-rpmh: Add BCMs to commit list in
pre_aggregate") was needed to actually drop bandwidth requests on unused
interconnects, of which the IPA was one of the interconnect that wasn't
getting dropped to zero. Combining the three commits together leads to
bad behavior where the interconnect framework is disabling the IP0
resource because it has no users while the clk framework thinks the IP0
resource is on because the only user, the IPA driver, has turned it on
via clk_prepare_enable(). Depending on when sync_state is called, we can
get into a situation like below:
IPA driver probes
IPA driver gets notified modem started
runtime PM get()
IPA clk enabled -> IP0 resource is ON
sync_state runs
interconnect zeroes out the IP0 resource -> IP0 resource is off
IPA driver tries to access a register and blows up
The crash is an unclocked access that manifest as an SError.

Remove all IP0 resource management from the interconnect driver so that
clk-rpmh is the sole owner. This fixes the issue by preventing the
interconnect driver from overwriting the IP0 resource data that the
clk-rpmh driver wrote.

[ Upstream commit ed46731d8e86c8d65f5fc717671e1f1f6c3146d2 ]
of_find_device_by_node() takes reference, we should use put_device()
to release it. when devm_kzalloc() fails, it doesn't have a
put_device(), it will cause refcount leak.
Add missing put_device() to fix this.
Fixes: 6a5f850aa83a ("ASoC: fsl: Add imx-hdmi machine driver")

From: Mickaël Salaün <[email protected]>
commit 5f2ff33e10843ef51275c8611bdb7b49537aba5d upstream.
Create and use the access_mask_t typedef to enforce a consistent access
mask size and uniformly use a 16-bits type. This will helps transition
to a 32-bits value one day.
Add a build check to make sure all (filesystem) access rights fit in.
This will be extended with a following commit.

[ Upstream commit 30b5e6ef4a32ea4985b99200e06d6660a69f9246 ]
The macros implementing Atari ROM port I/O writes do not cast away their
output, unlike similar implementations for other I/O buses.
When they are combined using conditional expressions in the definitions of
outb() and friends, this triggers sparse warnings like:
drivers/net/appletalk/cops.c:382:17: error: incompatible types in conditional expression (different base types):
drivers/net/appletalk/cops.c:382:17: unsigned char
drivers/net/appletalk/cops.c:382:17: void
Fix this by adding casts to "void".

commit b011946d039d66bbc7102137e98cc67e1356aa87 upstream.
The commit a69755b18774 ("xtensa simdisk: switch to proc_create_data()")
split read operation into two parts, first retrieving the path when it's
non-null and second retrieving the trailing '\n'. However when the path
is non-null the first simple_read_from_buffer updates ppos, and the
second simple_read_from_buffer returns 0 if ppos is greater than 1 (i.e.
almost always). As a result reading from that proc file is almost always
empty.
Fix it by making a temporary copy of the path with the trailing '\n' and
using simple_read_from_buffer on that copy.

From: Niels Dossche <[email protected]>
[ Upstream commit 51454ea42c1ab4e0c2828bb0d4d53957976980de ]
idev->addr_list needs to be protected by idev->lock. However, it is not
always possible to do so while iterating and performing actions on
inet6_ifaddr instances. For example, multiple functions (like
addrconf_{join,leave}_anycast) eventually call down to other functions
that acquire the idev->lock. The current code temporarily unlocked the
idev->lock during the loops, which can cause race conditions. Moving the
locks up is also not an appropriate solution as the ordering of lock
acquisition will be inconsistent with for example mc_lock.
This solution adds an additional field to inet6_ifaddr that is used
to temporarily add the instances to a temporary list while holding
idev->lock. The temporary list can then be traversed without holding
idev->lock. This change was done in two places. In addrconf_ifdown, the
list_for_each_entry_safe variant of the list loop is also no longer
necessary as there is no deletion within that specific loop.

[ Upstream commit f950667356ce90a41b446b726d4595a10cb65415 ]
Currently we look for waker only if current queue has no requests. This
makes sense for bfq queues with a single process however for shared
queues when there is a larger number of processes the condition that
queue has no requests is difficult to meet because often at least one
process has some request in flight although all the others are waiting
for the waker to do the work and this harms throughput. Relax the "no
queued request for bfq queue" condition to "the current task has no
queued requests yet". For this, we also need to start tracking number of
requests in flight for each task.
This patch (together with the following one) restores the performance
for dbench with 128 clients that regressed with commit c65e6fd460b4
("bfq: Do not let waker requests skip proper accounting") because
this commit makes requests of wakers properly enter BFQ queues and thus
these queues become ineligible for the old waker detection logic.
Dbench results:
Vanilla 5.18-rc3 5.18-rc3 + revert 5.18-rc3 patched
Mean 1237.36 ( 0.00%) 950.16 * 23.21%* 988.35 * 20.12%*
Numbers are time to complete workload so lower is better.

2.35.1
From: Kuppuswamy Sathyanarayanan <[email protected]>
[ Upstream commit 203926da2bff8e172200a2f11c758987af112d4a ]
When a Root Port or Root Complex Event Collector receives an error Message
e.g., ERR_COR, it sets PCI_ERR_ROOT_COR_RCV in the Root Error Status
register and logs the Requester ID in the Error Source Identification
register. If it receives a second ERR_COR Message before software clears
PCI_ERR_ROOT_COR_RCV, hardware sets PCI_ERR_ROOT_MULTI_COR_RCV and the
Requester ID is lost.
In the following scenario, PCI_ERR_ROOT_MULTI_COR_RCV was never cleared:
- hardware receives ERR_COR message
- hardware sets PCI_ERR_ROOT_COR_RCV
- aer_irq() entered
- aer_irq(): status = pci_read_config_dword(PCI_ERR_ROOT_STATUS)
- aer_irq(): now status == PCI_ERR_ROOT_COR_RCV
- hardware receives second ERR_COR message
- hardware sets PCI_ERR_ROOT_MULTI_COR_RCV
- aer_irq(): pci_write_config_dword(PCI_ERR_ROOT_STATUS, status)
- PCI_ERR_ROOT_COR_RCV is cleared; PCI_ERR_ROOT_MULTI_COR_RCV is set
- aer_irq() entered again
- aer_irq(): status = pci_read_config_dword(PCI_ERR_ROOT_STATUS)
- aer_irq(): now status == PCI_ERR_ROOT_MULTI_COR_RCV
- aer_irq() exits because PCI_ERR_ROOT_COR_RCV not set
- PCI_ERR_ROOT_MULTI_COR_RCV is still set
The same problem occurred with ERR_NONFATAL/ERR_FATAL Messages and
PCI_ERR_ROOT_UNCOR_RCV and PCI_ERR_ROOT_MULTI_UNCOR_RCV.
Fix the problem by queueing an AER event and clearing the Root Error Status
bits when any of these bits are set:
PCI_ERR_ROOT_COR_RCV
PCI_ERR_ROOT_UNCOR_RCV
PCI_ERR_ROOT_MULTI_COR_RCV
PCI_ERR_ROOT_MULTI_UNCOR_RCV
See the bugzilla link for details from Eric about how to reproduce this
problem.

From: Andrea Parri (Microsoft) <[email protected]>
[ Upstream commit 82cd4bacff88a11e36f143e2cb950174b09c86c3 ]
vmbus_request_addr() returns 0 (zero) if the transaction ID passed
to as argument is 0. This is unfortunate for two reasons: first,
netvsc_send_completion() does not check for a NULL cmd_rqst (before
dereferencing the corresponding NVSP message); second, 0 is a *valid*
value of cmd_rqst in netvsc_send_tx_complete(), cf. the call of
vmbus_sendpacket() in netvsc_send_pkt().
vmbus_request_addr() has included the code in question since its
introduction with commit e8b7db38449ac ("Drivers: hv: vmbus: Add
vmbus_requestor data structure for VMBus hardening"); such code was
motivated by the early use of vmbus_requestor by hv_storvsc. Since
hv_storvsc moved to a tag-based mechanism to generate and retrieve
transaction IDs with commit bf5fd8cae3c8f ("scsi: storvsc: Use
blk_mq_unique_tag() to generate requestIDs"), vmbus_request_addr()
can be modified to return VMBUS_RQST_ERROR if the ID is 0. This
change solves the issues in hv_netvsc (and makes the handling of
messages with transaction ID of 0 consistent with the semantics
"the ID is not contained in the requestor/invalid ID").
vmbus_next_request_id(), vmbus_request_addr() should still reserve
the ID of 0 for Hyper-V, because Hyper-V will "ignore" (not respond
to) VMBUS_DATA_PACKET_FLAG_COMPLETION_REQUESTED packets/requests with
transaction ID of 0 from the guest.

From: Andre Przywara <[email protected]>
[ Upstream commit d7a49291d786b4400996afe3afcc3ef5eeb6f0ef ]
The "bti" selftests are built with -nostdlib, which apparently
automatically creates a statically linked binary, which is what we want
and need for BTI (to avoid interactions with the dynamic linker).
However this is not true when building a PIE binary, which some
toolchains (Ubuntu) configure as the default.
When compiling btitest with such a toolchain, it will create a
dynamically linked binary, which will probably fail some tests, as the
dynamic linker might not support BTI:
===================
TAP version 13
1..18
not ok 1 nohint_func/call_using_br_x0
not ok 2 nohint_func/call_using_br_x16
not ok 3 nohint_func/call_using_blr
....
===================
To make sure we create static binaries, add an explicit -static on the
linker command line. This forces static linking even if the toolchain
defaults to PIE builds, and fixes btitest runs on BTI enabled machines.

[ Upstream commit ce216cfa84a4e1c23b105e652c550bdeaac9e922 ]
Add a quirk for the HP Pro Tablet 408, this BYTCR tablet has no CHAN
package in its ACPI tables and uses SSP0-AIF1 rather then SSP0-AIF2 which
is the default for BYTCR devices.
It also uses DMIC1 for the internal mic rather then the default IN3
and it uses JD2 rather then the default JD1 for jack-detect.

[ Upstream commit bca1a1004615efe141fd78f360ecc48c60bc4ad5 ]
This reverts commit c7dacf5b0f32957b24ef29df1207dc2cd8307743,
"mailbox: avoid timer start from callback"
The previous commit was reverted since it lead to a race that
caused the hrtimer to not be started at all. The check for
hrtimer_active() in msg_submit() will return true if the
callback function txdone_hrtimer() is currently running. This
function could return HRTIMER_NORESTART and then the timer
will not be restarted, and also msg_submit() will not start
the timer. This will lead to a message actually being submitted
but no timer will start to check for its compleation.
The original fix that added checking hrtimer_active() was added to
avoid a warning with hrtimer_forward. Looking in the kernel
another solution to avoid this warning is to check hrtimer_is_queued()
before calling hrtimer_forward_now() instead. This however requires a
lock so the timer is not started by msg_submit() inbetween this check
and the hrtimer_forward() call.

[ Upstream commit 64b22a0da12adb571c01edd671ee43634ebd7e41 ]
If there are errors while trying to enable the pm in the
bind path, it will lead to unclocked access of hw revision
register thereby crashing the device.
This will not address why the pm_runtime_get_sync() fails
but at the very least we should be able to prevent the
crash by handling the error and bailing out earlier.
changes in v2:
- use pm_runtime_resume_and_get() instead of
pm_runtime_get_sync()

From: Josh Poimboeuf <[email protected]>
[ Upstream commit 1d1a0e7c5100d332583e20b40aa8c0a8ed3d7849 ]
There have been some recent reports of faddr2line failures:
$ scripts/faddr2line sound/soundcore.ko sound_devnode+0x5/0x35
bad symbol size: base: 0x0000000000000000 end: 0x0000000000000000
$ ./scripts/faddr2line vmlinux.o enter_from_user_mode+0x24
bad symbol size: base: 0x0000000000005fe0 end: 0x0000000000005fe0
The problem is that faddr2line is based on 'nm', which has a major
limitation: it doesn't know how to distinguish between different text
sections. So if an offset exists in multiple text sections in the
object, it may fail.
Rewrite faddr2line to be section-aware, by basing it on readelf.

[ Upstream commit 8ce5ef64546850294b021497046588a7abcebe96 ]
Add support for deferring other params like PIN_CONFIG_INPUT_ENABLE.
This will be used to add support for PIN_CONFIG_INPUT_ENABLE to the
driver.
Fixes: e7165b1dff06 ("pinctrl/rockchip: add a queue for deferred pin output settings on probe")

From: Sakari Ailus <[email protected]>
commit 3bd561e1572ee02a50cd1a5be339abf1a5b78d56 upstream.
struct acpi_device_properties describes one source of properties present
on either struct acpi_device or struct acpi_data_node. When properties are
parsed, both are populated but when released, only those properties that
are associated with the device node are freed.
Fix this by also releasing memory of the data node properties.

The lock held by ext4_convert_inline_data is xattr_sem, but the lock
held by generic_perform_write is i_rwsem. Therefore, the two locks can
be concurrent.
To solve above issue, we add inode_lock() for ext4_convert_inline_data().
At the same time, move ext4_convert_inline_data() in front of
ext4_punch_hole(), remove similar handling from ext4_punch_hole().

This commit therefore fixes this issue by applying a single-CPU
optimization to the RCU Tasks Rude grace-period process. The key point
here is that the purpose of this RCU flavor is to force a schedule on
each online CPU since some past event. But the rcu_tasks_rude_wait_gp()
function runs in the context of the RCU Tasks Rude's grace-period kthread,
so there must already have been a context switch on the current CPU since
the call to either synchronize_rcu_tasks_rude() or call_rcu_tasks_rude().
So if there is only a single CPU online, RCU Tasks Rude's grace-period
kthread does not need to anything at all.
It turns out that the rcu_tasks_rude_wait_gp() function's call to
schedule_on_each_cpu() causes problems during early boot. During that
time, there is only one online CPU, namely the boot CPU. Therefore,
applying this single-CPU optimization fixes early-boot instances of
this problem.

The spi which's version is higher than ver 2 will automatically
enable this feature.
If the length of master transmission is uncertain, the RK spi slave
is better to automatically stop after cs inactive instead of waiting
for xfer_completion forever.

commit cfd66bb715fd11fde3338d0660cffa1396adc27d upstream.
As Yanming reported in bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=215914
The root cause is: in a very small sized image, it's very easy to
exceed threshold of foreground GC, if we calculate free space and
dirty data based on section granularity, in corner case,
has_not_enough_free_secs() will always return true, result in
deadloop in f2fs_gc().
So this patch refactors has_not_enough_free_secs() as below to fix
this issue:
1. calculate needed space based on block granularity, and separate
all blocks to two parts, section part, and block part, comparing
section part to free section, and comparing block part to free space
in openned log.
2. account F2FS_DIRTY_NODES, F2FS_DIRTY_IMETA and F2FS_DIRTY_DENTS
as node block consumer;
3. account F2FS_DIRTY_DENTS as data block consumer;

The btf__load_from_kernel_by_id() only takes one arg, not two.
Committer notes:
I tested it just with an older libbpf, one where
btf__load_from_kernel_by_id() wasn't introduced yet.
A test with a newer dynamic libbpf would fail because the
btf__load_from_kernel_by_id() is there, but takes just one arg.

From: Lin Ma <[email protected]>
[ Upstream commit 2def44d3aec59e38d2701c568d65540783f90f2f ]
There is a logic error when removing rt5645 device as the function
rt5645_i2c_remove() first cancel the &rt5645->jack_detect_work and
delete the &rt5645->btn_check_timer latter. However, since the timer
handler rt5645_btn_check_callback() will re-queue the jack_detect_work,
this cleanup order is buggy.
That is, once the del_timer_sync in rt5645_i2c_remove is concurrently
run with the rt5645_btn_check_callback, the canceled jack_detect_work
will be rescheduled again, leading to possible use-after-free.
This patch fix the issue by placing the del_timer_sync function before
the cancel_delayed_work_sync.

[ Upstream commit 15eb77f873255cf9f4d703b63cfbd23c46579654 ]
Boot memory area is setup as separate PT_LOAD segment in the vmcore
as it is moved by f/w, on crash, to a destination address provided by
the kernel. Having separate PT_LOAD segment helps in handling the
different physical address and offset for boot memory area in the
vmcore.
Commit ced1bf52f477 ("powerpc/fadump: merge adjacent memory ranges to
reduce PT_LOAD segements") inadvertly broke this pre-condition for
cases where some of the first kernel memory is available adjacent to
boot memory area. This scenario is rare but possible when memory for
fadump could not be reserved adjacent to boot memory area owing to
memory hole or such. Reading memory from a vmcore exported in such
scenario provides incorrect data. Fix it by ensuring no other region
is folded into boot memory area.

From: Emmanuel Grumbach <[email protected]>
commit 9d096e3d3061dbf4ee10e2b59fc2c06e05bdb997 upstream.
When we reconfig we must not send the MAC_POWER command that relates to
a MAC that was not yet added to the firmware.
Ignore those in the iterator.

Functions in the DisplayPort code that relates to individual instances
(encoders) are passed both the struct msm_dp and the struct drm_encoder.
But in a situation where multiple DP instances would exist this means
that the caller need to resolve which struct msm_dp relates to the
struct drm_encoder at hand.
Store a reference to the struct msm_dp associated with each
dpu_encoder_virt to allow the particular instance to be associate with
the encoder in the following patch.

If we program an RX endpoint to have no header (header length is 0),
header-related endpoint configuration values are meaningless and are
ignored.
The only case we support that defines a header is QMAP endpoints.
In ipa_endpoint_init_hdr_ext() we set the endianness mask value
unconditionally, but it should not be done if there is no header
(meaning it is not configured for QMAP).
Set the endianness conditionally, and rearrange the logic in that
function slightly to avoid testing the qmap flag twice.
Delete an incorrect comment in ipa_endpoint_init_aggr().

[ Upstream commit 52fde2c07da606f3f120af4f734eadcfb52b04be ]
The nvme specification only requires qword alignment for segment
descriptors, and the driver already guarantees that. The spec has always
allowed user data to be dword aligned, which is what the queue's
attribute is for, so relax the alignment requirement to that value.
While we could allow byte alignment for some controllers when using
SGLs, we still need to support PRP, and that only allows dword.

The bug is here:
p->target_id, p->target_lun);
The list iterator 'p' will point to a bogus position containing HEAD if the
list is empty or no element is found. This case must be checked before any
use of the iterator, otherwise it will lead to an invalid memory access.
To fix this bug, add a check. Use a new variable 'iter' as the list
iterator, and use the original variable 'p' as a dedicated pointer to point
to the found element.

[ Upstream commit 4efc851c36e389f7ed432edac0149acc5f94b0c7 ]
Currently the EXIU uses the fasteoi interrupt flow that is configured by
it's parent (irq-gic-v3.c). With this flow the only chance to clear the
interrupt request happens during .irq_eoi() and (obviously) this happens
after the interrupt handler has run. EXIU requires edge triggered
interrupts to be acked prior to interrupt handling. Without this we
risk incorrect interrupt dismissal when a new interrupt is delivered
after the handler reads and acknowledges the peripheral but before the
irq_eoi() takes place.
Fix this by clearing the interrupt request from .irq_ack() if we are
configured for edge triggered interrupts. This requires adopting the
fasteoi-ack flow instead of the fasteoi to ensure the ack gets called.
These changes have been tested using the power button on a
Developerbox/SC2A11 combined with some hackery in gpio-keys so I can
play with the different trigger mode [and an mdelay(500) so I can
can check what happens on a double click in both modes].

[ Upstream commit c56de483093d7ad0782327f95dda7da97bc4c315 ]
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
a6xx_gmu_init() passes the node to of_find_device_by_node()
and of_dma_configure(), of_find_device_by_node() will takes its
reference, of_dma_configure() doesn't need the node after usage.
Add missing of_node_put() to avoid refcount leak.

[ Upstream commit 2dcec57b3734029cc1adc5cb872f61e21609eed4 ]
The chip register layout has nothing to do with MIPI DCS, the registers
incorrectly marked as MIPI DCS in the driver are regular chip registers
often with completely different function.
Fill in the actual register names and bits from [1] and [2] and add the
entire register layout, since the documentation for this chip is hard to
come by.

From: Charles Keepax <[email protected]>
[ Upstream commit 52857c3baa0e5ddeba7b2c84e56bb71c9674e048 ]
The endianness flag should have been removed when the driver was
ported across from having both a CODEC and CPU side component, to
just having a CPU component and using the dummy for the CODEC. The
endianness flag is used to indicate that the device is completely
ambivalent to the endianness of the data, typically due to the
endianness being lost over the hardware link (ie. the link defines
bit ordering). It's usage didn't have any effect when the driver
had both a CPU and CODEC component, since the union of those equals
the CPU side settings, but now causes the driver to falsely report
it supports big endian. Correct this by removing the flag.

When a process exits, /proc/${pid}, and /proc/${pid}/net dentries are
flushed. However some leaf dentries like /proc/${pid}/net/arp_cache
aren't. That's because respective PDEs have proc_misc_d_revalidate() hook
which returns 1 and leaves dentries/inodes in the LRU.
Force revalidation/lookup on everything under /proc/${pid}/net by
inheriting proc_net_dentry_ops.

2.35.1
From: Hans Verkuil <[email protected]>
[ Upstream commit 59267fc34f4900dcd2ec3295f6be04b79aee2186 ]
If an adapter is trying to claim a free logical address then it is
in the 'is_configuring' state. If during that process the cable is
disconnected (HPD goes low, which in turn invalidates the physical
address), then cec_adap_unconfigure() is called, and that set the
is_configuring boolean to false, even though the thread that's
trying to claim an LA is still running.
Don't touch the is_configuring bool in cec_adap_unconfigure(), it
will eventually be cleared by the thread. By making that change
the cec_config_log_addr() function also had to change: it was
aborting if is_configuring became false (since that is what
cec_adap_unconfigure() did), but that no longer works. Instead
check if the physical address is invalid. That is a much
more appropriate check anyway.
This fixes a bug where the the adapter could be disabled even
though the device was still configuring. This could cause POLL
transmits to time out.

I did not mention powerpc allmodconfig failed to build as I have just
started building that arch and I did not have a good build to know if
its a new failure or not.
But It failed with the error:
{standard input}: Assembler messages:
{standard input}:255: Error: unrecognized opcode: `dssall'
make[2]: *** [scripts/Makefile.build:288: arch/powerpc/mm/mmu_context.o] Error 1
and will need - d51f86cfd8e3 ("powerpc/mm: Switch obsolete dssall to .long")

It is not new with gcc 11.3 and binutils 2.38. I currently use gcc 11.2.0
combined with binutils 2.36.1 for building powerpc images (binutils 2.37
won't work, at least not with gcc 11.2).

With this patch applied, at least the affected file builds with gcc 11.3 /
binutils 2.38. I have not tried to build the entire image, though, with that
combination.
