4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Roger Quadros <[email protected]>
commit 084a804e01205bcd74cd0849bc72cb5c88f8e648 upstream.
To reproduce the lock up do the following
- connect otg host adapter and a USB device to the dual-role port
so that it is in host mode.
- suspend to mem.
- disconnect otg adapter.
- resume the system.
If we call dwc3_host_exit() before tasks are thawed
xhci_plat_remove() seems to lock up at the second usb_remove_hcd() call.
To work around this we queue the _dwc3_set_mode() work on
the system_freezable_wq.
Fixes: 41ce1456e1db ("usb: dwc3: core: make dwc3_set_mode() work properly")

commit 2d30e9494f1ea320aaaad0cff9ddd92c87eac355 upstream.
The ALC5651 does not like multi-write accesses, avoid them. This fixes:
rt5651 i2c-10EC5651:00: Unable to sync registers 0x27-0x28. -121
Errors on resume (and all registers after the registers in the error not

This splat cannot be generated by expedited grace periods because they
always invoke resched_cpu() on the current CPU, which is good because
expedited grace periods require that resched_cpu() unconditionally
succeed. However, other parts of RCU can tolerate resched_cpu() acting
as a no-op, at least as long as it doesn't happen too often.
This commit therefore makes resched_cpu() invoke resched_curr() only if
the CPU is either online or is the current CPU.

This is a followup on 44117a1d1732 ("serial: core: mark port as
initialized after successful IRQ change").
Nikola has been using autoconfig via setserial and reported a crash
similar to what I fixed in the earlier mentioned commit. Here I do the
same fixup for the autoconfig. I wasn't sure that this is the right
approach. Nikola confirmed that it fixes his crash.

From: Miquel Raynal <[email protected]>
[ Upstream commit df467899da0b71465760b4e35127bce837244eee ]
Some drivers (like nand_hynix.c) call ->cmdfunc() with NAND_CMD_NONE
and a column address and expect the controller to only send address
cycles. Right now, the default ->cmdfunc() implementations provided by
the core do not filter out the command cycle in this case and forwards
the request to the controller driver through the ->cmd_ctrl() method.
The thing is, NAND controller drivers can get this wrong and send a
command cycle with a NAND_CMD_NONE opcode and since NAND_CMD_NONE is
-1, and the command field is usually casted to an u8, we end up sending
the 0xFF command which is actually a RESET operation.
Add conditions in nand_command[_lp]() functions to sending the initial
command cycle when command == NAND_CMD_NONE.

On some dual port NICs, the 2 ports have to be configured with compatible
link speeds. Under some conditions, a port's configured speed may no
longer be supported. The firmware will send a message to the driver
when this happens.
Improve this logic that prints out the warning by only printing it if
we can determine the link speed that is no longer supported. If the
speed is unknown or it is in autoneg mode, skip the warning message.

[ Upstream commit 61e06e2c3ebd986050958513bfa40dceed756f8f ]
The raid set size is being revalidated unconditionally before a
reshaping conversion is started. MD requires the size to only be
reduced in case of a stripe removing (i.e. shrinking) reshape but not
when growing because the raid array has to stay small until after the
growing reshape finishes.
Fix by avoiding the size revalidation in preresume unless a shrinking
reshape is requested.

HITACHI is always supporting VPD pages, even though it's claiming to
support SCSI Revision 3 only.
The same should have been done also for HP-rebranded.

[ Upstream commit a8b149d32b663c1a4105273295184b78f53d33cf ]
It is possible to remove a cpufreq governor module after
cpufreq_parse_governor() has returned success in
store_scaling_governor() and before cpufreq_set_policy()
acquires a reference to it, because the governor list is
not protected during that period and nothing prevents the
governor from being unregistered then.
Prevent that from happening by acquiring an extra reference
to the governor module temporarily in cpufreq_parse_governor(),
under cpufreq_governor_mutex, and dropping it in
store_scaling_governor(), when cpufreq_set_policy() returns.
Note that the second cpufreq_parse_governor() call site is fine,
because it only cares about the policy member of new_policy.

In the ieee80211_setup_sdata() we check if the interface type is valid
and, if not, call BUG(). This should never happen, but if there is
something wrong with the code, it will not be caught until the bug
happens when an interface is being set up. Calling BUG() is too
extreme for this and a WARN_ON() would be better used instead. Change
that.

Driver is missing the interrupts if two requests are queued up at the same
time as the interrupt handler is servicing a request that was just
delivered.
The ISR clears the interrupt at the end but it could be clearing the
interrupt for an outstanding event. Therefore, second interrupt never
arrives.
Clear the interrupt first and then check for completions.
Also, make sure that request start and interrupt clear do not overlap in
time by using a spinlock.

I've looked at all those findings again and noticed that they are all
with CONFIG_INFINIBAND_USER_MEM=n, which means ib_umem_get() returns
an error unconditionally and we never initialize or use those variables.
This triggers a condition in gcc iff mr_umem_get() is partially but not
entirely inlined, which in turn depends on the exact combination of
optimization settings. This is a known problem with gcc, with no
easy solution in the compiler, so this adds another workaround that
should be more reliable than my previous attempt.
Returning an error from mlx5_ib_reg_user_mr() earlier means that we
can completely bypass the logic that caused the warning, the compiler
can now see that the variable is never accessed.

[ Upstream commit b7e27bc1d42e8e0cc58b602b529c25cd0071b336 ]
Custom policies can require file signatures based on LSM labels. These
files are normally created and only afterwards labeled, requiring them
to be signed.
Instead of requiring file signatures based on LSM labels, entire
filesystems could require file signatures. In this case, we need the
ability of writing new files without requiring file signatures.
The definition of a "new" file was originally defined as any file with
a length of zero. Subsequent patches redefined a "new" file to be based
on the FILE_CREATE open flag. By combining the open flag with a file
size of zero, this patch relaxes the file signature requirement.

The 'configinit.sh' script checks the format of optional argument for the

However, the error message uses the wrong variable, indicating an empty

This commit fixes the script to use the correct variable.

------------------
From: Thomas Richter <[email protected]>
[ Upstream commit 36c263607d36c6a3788c09301d9f5fe35404048a ]
This patch fixes a bug introduced with commit d9f8dfa9baf9 ("perf
annotate s390: Implement jump types for perf annotate").
'perf annotate' displays annotated assembler output by reading output of
command objdump and parsing the disassembled lines. For each shown
mnemonic this function sequence is executed:
disasm_line__new()
|
+--> disasm_line__init_ins()
|
+--> ins__find()
|
+--> arch->associate_instruction_ops()
The s390x specific function assigned to function pointer
associate_instruction_ops refers to function s390__associate_ins_ops().
This function checks for supported mnemonics and assigns a NULL pointer
to unsupported mnemonics. However even the NULL pointer is added to the
architecture dependend instruction array.
This leads to an extremely large architecture instruction array
(due to array resize logic in function arch__grow_instructions()).
Depending on the objdump output being parsed the array can end up
with several ten-thousand elements.
This patch checks if a mnemonic is supported and only adds supported
ones into the architecture instruction array. The array does not contain
elements with NULL pointers anymore.
Before the patch (With some debug printf output):
[root@s35lp76 perf]# time ./perf annotate --stdio > /tmp/xxxbb
real 8m49.679s
user 7m13.008s
sys 0m1.649s
[root@s35lp76 perf]# fgrep '__ins__find sorted:1 nr_instructions:'
/tmp/xxxbb | tail -1
__ins__find sorted:1 nr_instructions:87433 ins:0x341583c0
[root@s35lp76 perf]#
The number of different s390x branch/jump/call/return instructions
entered into the array is 87433.
After the patch (With some printf debug output:)
[root@s35lp76 perf]# time ./perf annotate --stdio > /tmp/xxxaa
real 1m24.553s
user 0m0.587s
sys 0m1.530s
[root@s35lp76 perf]# fgrep '__ins__find sorted:1 nr_instructions:'
/tmp/xxxaa | tail -1
__ins__find sorted:1 nr_instructions:56 ins:0x3f406570
[root@s35lp76 perf]#
The number of different s390x branch/jump/call/return instructions
entered into the array is 56 which is sensible.

Packets that don't have dest mac as the mac of the master device should
not be entertained by the IPvlan rx-handler. This is mostly true as the
packet path mostly takes care of that, except when the master device is
a virtual device. As demonstrated in the following case -
ip netns add ns1
ip link add ve1 type veth peer name ve2
ip link add link ve2 name iv1 type ipvlan mode l2
ip link set dev iv1 netns ns1
ip link set ve1 up
ip link set ve2 up
ip -n ns1 link set iv1 up
ip addr add 192.168.10.1/24 dev ve1
ip -n ns1 addr 192.168.10.2/24 dev iv1
ping -c2 192.168.10.2
<Works!>
ip neigh show dev ve1
ip neigh show 192.168.10.2 lladdr <random> dev ve1

Enforce using PS_MANUAL_POLL in ps hwsim debugfs to trigger a poll,
only if PS_ENABLED was set before.
This is required due to commit c9491367b759 ("mac80211: always update the
PM state of a peer on MGMT / DATA frames") that enforces the ap to
check only mgmt/data frames ps bit, and then update station's power save
accordingly.
When sending only ps-poll (control frame) the ap will not be aware that
the station entered power save.
Setting ps enable before triggering ps_poll, will send NDP with PM bit
enabled first.

[ Upstream commit acb1feab320e38588fccc568e3767761f494976f ]
When an interrupt is returning to a soft-disabled context (which can
happen for non-maskable interrupts or synchronous interrupts), it goes
through the motions of soft-disabling again, including calling
TRACE_DISABLE_INTS (i.e., trace_hardirqs_off()).
This is not necessary, because we must already be soft-disabled in the
interrupt context, it also may be causing crashes in the irq tracing
code to re-enter as an nmi. Replace it with a warning to ensure that
soft-interrupts are still disabled.

[ Upstream commit 8516673a996870ea0ceb337ee4f83c33c5ec3111 ]
Before accessing the GGTT we must flush the PTE writes and make them
visible to the chipset, or else the indirect access may end up in the
wrong page. In commit 3497971a71d8 ("agp/intel: Flush chipset writes
after updating a single PTE"), we noticed corruption of the uploads for
pwrite and for capturing GPU error states, but it was presumed that the
explicit calls to intel_gtt_chipset_flush() were sufficient for the
execbuffer path. However, we have not been flushing the chipset between
the PTE writes and access via the GTT itself.
For simplicity, do the flush after any PTE update rather than try and
batch the flushes on a just-in-time basis.

[ Upstream commit f5bbcd533a9d1af97b8a0862a421bb8455f1bf6d ]
Describe the GPIO used to reset the Ethernet PHY for EthernetAVB.
This allows the driver to reset the PHY during probe and after system
resume.
This fixes Ethernet operation after resume from s2ram on Salvator-XS,
where the enable pin of the regulator providing PHY power is connected
to PRESETn, and PSCI powers down the SoC during system suspend.
On Salvator-X, the enable pin is always pulled high, but the driver may
still need to reset the PHY if this wasn't done by the bootloader
before.
Inspired by patches in the BSP for the individual Salvator-X/XS boards
by Kazuya Mizuguchi.

[ Upstream commit 7bbde83b1860c28a1cc35516352c4e7e5172c29a ]
In qdisc_graft_qdisc a "new" qdisc is attached and the 'qdisc_destroy'
operation is called on the old qdisc. The destroy operation will wait
a rcu grace period and call qdisc_rcu_free(). At which point
gso_cpu_skb is free'd along with all stats so no need to zero stats
and gso_cpu_skb from the graft operation itself.
Further after dropping the qdisc locks we can not continue to call
qdisc_reset before waiting an rcu grace period so that the qdisc is
detached from all cpus. By removing the qdisc_reset() here we get
the correct property of waiting an rcu grace period and letting the
qdisc_destroy operation clean up the qdisc correctly.
Note, a refcnt greater than 1 would cause the destroy operation to
be aborted however if this ever happened the reference to the qdisc
would be lost and we would have a memory leak.

When attempting to load a livepatch module, I got the following error:
module_64: patch_module: Expect noop after relocate, got 3c820000
The error was triggered by the following code in
unregister_netdevice_queue():
14c: 00 00 00 48 b 14c <unregister_netdevice_queue+0x14c>
14c: R_PPC64_REL24 net_set_todo
150: 00 00 82 3c addis r4,r2,0
GCC didn't insert a nop after the branch to net_set_todo() because it's
a sibling call, so it never returns. The nop isn't needed after the
branch in that case.

When used as part of a display pipeline, the VSP is stopped and
restarted explicitly by the DU from its suspend and resume handlers.
There is thus no need to stop or restart pipelines in the VSP suspend

left in a misconfigured state.
Ensure that the VSP suspend and resume handlers do not affect DRM-based

Since commit 39e6c8208d7b ("net: solve a NAPI race") napi has been able
to be rescheduled within napi_complete_done() even in non-busypoll case,
but virtnet_poll() always enabled interrupts before complete, and when
napi was rescheduled within napi_complete_done() it did not disable
interrupts.
This caused more interrupts when event idx is disabled.
According to commit cbdadbbf0c79 ("virtio_net: fix race in RX VQ
processing") we cannot place virtqueue_enable_cb_prepare() after
NAPI_STATE_SCHED is cleared, so disable interrupts again if
napi_complete_done() returned false.
Tested with vhost-user of OVS 2.7 on host, which does not have the event
idx feature.

[ Upstream commit a44c9d36509c83cf64f33b93f6ab2e63822c01eb ]
Since scsi_get_device_flags_keyed() callers do not check whether or not
the returned value is an error code, change that function such that it
returns a flags value even if the 'key' argument is invalid. Note:
since commit 28a0bc4120d3 ("scsi: sd: Implement blacklist option for
WRITE SAME w/ UNMAP") bit 31 is a valid device information flag so
checking whether bit 31 is set in the return value is not sufficient to
tell the difference between an error code and a flags value.

sun6i_spi_probe() uses sun6i_spi_runtime_resume() to prepare/enable
clocks, so sun6i_spi_remove() should use sun6i_spi_runtime_suspend() to
disable/unprepare them if we're not suspended.
Replacing pm_runtime_disable() by pm_runtime_force_suspend() will ensure
that sun6i_spi_runtime_suspend() is called if needed.

From: Thomas Richter <[email protected]>
[ Upstream commit 35a8a148d8c1ee9e5ae18f9565a880490f816f89 ]
The command 'perf annotate' parses the output of objdump and also
investigates the comments produced by objdump. For example the
output of objdump produces (on x86):
23eee: 4c 8b 3d 13 01 21 00 mov 0x210113(%rip),%r15
# 234008 <stderr@@GLIBC_2.2.5+0x9a8>
and the function mov__parse() is called to investigate the complete
line. Mov__parse() breaks this line into several parts and finally
calls function comment__symbol() to parse the data after the comment
character '#'. Comment__symbol() expects a hexadecimal address followed
by a symbol in '<' and '>' brackets.
However the 2nd parameter given to function comment__symbol()
always points to the comment character '#'. The address parsing
always returns 0 because the character '#' is not a digit and
strtoull() fails without being noticed.
Fix this by advancing the second parameter to function comment__symbol()
by one byte before invocation and add an error check after strtoull()
has been called.

We might erroneously get to error dumping code when the
device is already stopped.
In that case the driver will detect a defective value and will try to
reset the HW, assuming it is only a bus issue. The driver than
proceeds with the dumping.
The result has two side effects:
1. The device won't be stopped again, since the transport status is
already stopped, so the device remains powered on while it actually
should be stopped.
2. The dump in that case is completely garbaged and useless.
Detect and avoid this. It will also make debugging such issues
easier.

[ Upstream commit 992172e3aec19e5b0ea5b757ba40a146b9282d1e ]
When we are in a search cycle, we try different combinations
of parameters. Those combinations are called 'columns'.
When we switch to a new column, we first need to check if
this column has a suitable rate, if not, we can't try it.
This means we must not erase the statistics we gathered
for the previous column until we are sure that we are
indeed switching column.
The code that tries to switch to a new column first sets
a whole bunch of things for the new column, and only then
checks that we can find suitable rates in that column.
While doing that, the code mistakenly erased the rate
statistics. This code was right until
struct iwl_scale_tbl_info grew up for TPC.
Fix this to make sure we don't erase the rate statistics
until we are sure that we can indeed switch to the new
column.
Note that this bug is really harmless since it causes a
change in the behavior only when we can't find any rate
in the new column which should really not happen. In the
case we do find a suitable we reset the rate statistics
a few lines later anyway.

cec-clock is a fixed clock generator that is not controlled by i2c5 and
thus should not be a child of the i2c5 bus node. Rather, it should be
a child of the root node of the DT.

[ Upstream commit 55746d28d66860bccaae20a67b55b9d5db7c14af ]
Devices in "single finger hybrid mode" will send one report per finger,
on some devices only the first report of such a multi-packet frame will
contain a value for BTN_LEFT, in subsequent reports (if multiple fingers
are down) the value is always 0, causing hid-mt to report BTN_LEFT going
1 - 0 - 1 - 0 when pressing a clickpad and putting down a second finger.
This happens for example on USB 0603:0002 mt touchpads.
This commit fixes this by only reporting non touch fields for the first
packet of a (possibly) multi-packet frame.

It is required to update the teardown state of the peer when
a tdls link with that peer is terminated. This information is
useful for the target to perform some cleanups wrt the tdls peer.
Without proper cleanup, target assumes that the peer is connected and
blocks future connection requests, updating the teardown state of the
peer addresses the problem.
Tested this change on QCA9888 with 10.4-3.5.1-00018 fw version.

go through the error handling path directly.
Before commit db43e6c473b5 ("ab8500-bm: Add usb power path support") this
was the case, but this commit has added some code between the last test and
the 'out' label.
So, in case of error, this added code is executed and the error may be
silently ignored.
Fix it by adding the missing 'goto out', as done in all other error
handling paths.

When vfs_submount was added the test to limit automounts from
filesystems that with s_user_ns != &init_user_ns accidentially left
in follow_automount. The test was never about any security concerns
and was always about how do we implement this for filesystems whose
s_user_ns != &init_user_ns.
At the moment this check makes no difference as there are no
filesystems that both set FS_USERNS_MOUNT and implement d_automount.
Remove this check now while I am thinking about it so there will not
be odd booby traps for someone who does want to make this combination
work.
vfs_submount still needs improvements to allow this combination to work,
and vfs_submount contains a check that presents a warning.
The autofs4 filesystem could be modified to set FS_USERNS_MOUNT and it would
need not work on this code path, as userspace performs the mounts.

From: Lorenzo Colitti <[email protected]>
[ Upstream commit be8f8284cd897af2482d4e54fbc2bdfc15557259 ]
Currently it is possible to add or update socket policies, but
not clear them. Therefore, once a socket policy has been applied,
the socket cannot be used for unencrypted traffic.
This patch allows (privileged) users to clear socket policies by
passing in a NULL pointer and zero length argument to the
{IP,IPV6}_{IPSEC,XFRM}_POLICY setsockopts. This results in both
the incoming and outgoing policies being cleared.
The simple approach taken in this patch cannot clear socket
policies in only one direction. If desired this could be added
in the future, for example by continuing to pass in a length of
zero (which currently is guaranteed to return EMSGSIZE) and
making the policy be a pointer to an integer that contains one
of the XFRM_POLICY_{IN,OUT} enum values.
An alternative would have been to interpret the length as a
signed integer and use XFRM_POLICY_IN (i.e., 0) to clear the
input policy and -XFRM_POLICY_OUT (i.e., -1) to clear the output
policy.

The file /sys/module/firmware_class/parameters/path can be used
to set a custom firmware path. The fw_filesystem.sh script creates
a temporary directory to add a test firmware file to be used during
testing, in order for this to work it uses the custom path syfs file
and it was supposed to reset back the file on execution exit. The
script failed to do this due to a typo, it was using OLD_PATH instead
of OLD_FWPATH, since its inception since v3.17.
Its not as easy to just keep the old setting, it turns out that
resetting an empty setting won't actually do what we want, we need
to check if it was empty and set an empty space.
Without this we end up having the temporary path always set after
we run these tests.

But the target task's priority has already been adjusted, so the only
purpose of switched_to_rt() invoking resched_curr() is to wake up the
CPU running some task that needs to be preempted by the boosted task.
But the CPU is offline, which presumably means that the task must be
migrated to some other CPU, and that this other CPU will undertake any
needed preemption at the time of migration. Because the runqueue lock
is held when resched_curr() is invoked, we know that the boosted task
cannot go anywhere, so it is not necessary to invoke resched_curr()
in this particular case.
This commit therefore makes switched_to_rt() refrain from invoking
resched_curr() when the target CPU is offline.

From: Adam Thomson <[email protected]>
[ Upstream commit ab69f61321140ff632d560775bc226259a78dfa2 ]
The expectation in the FUSB302 driver is that a TX_SUCCESS event
should occur after a message has been sent, but before a GCRCSENT
event is raised to indicate successful receipt of a message from
the partner. However in some circumstances it is possible to see
the hardware raise a GCRCSENT event before a TX_SUCCESS event
is raised. The upshot of this is that the GCRCSENT handling portion
of code ends up reporting the GoodCRC message to TCPM because the
TX_SUCCESS event hasn't yet arrived to trigger a consumption of it.
When TX_SUCCESS is then raised by the chip it ends up consuming the
actual message that was meant for TCPM, and this incorrect sequence
results in a hard reset from TCPM.
To avoid this problem, this commit updates the message reading
code to check whether a GoodCRC message was received or not. Based
on this check it will either report that the previous transmission
has completed or it will pass the msg data to TCPM for futher
processing. This way the incorrect ordering of the events no longer
matters.

commit a8992973edbb2555e956b90f6fe97c4bc14d761d upstream.
Commit 8419caa72702 ("ASoC: sgtl5000: Do not disable regulators in
SND_SOC_BIAS_OFF") causes the sgtl5000 to fail after a suspend/resume
sequence:

aplay: pcm_write:2051: write error: Input/output error
The problem is caused by the fact that the aforementioned commit
dropped the cache handling, so re-introduce the register map
resync to fix the problem.

From: Richard Fitzgerald <[email protected]>
commit d7789f5bcdb298c4a302db471b1b20f74a20de95 upstream.
Normal 512-byte get/set of a TLV isn't supported but we were
registering the normal get/set anyway and relying on omitting
the SNDRV_CTL_ELEM_ACCESS_[READ|WRITE] flags to prevent them
being called.
Trouble is if this gets broken in the core ALSA code - as it has
been since at least 4.14 - the standard get/set can be called
unexpectedly and corrupt memory.
There's no point providing functions that won't be called and
it's a trivial change. The benefit is that if the ALSA core gets
broken again we get a big fat immediate NULL dereference instead
of a memory corruption timebomb.

After v4.12 commit e2460f2a4bc7 ("dm: mark targets that pass integrity
data"), dm-multipath, e.g. on DIF+DIX SCSI disk paths, does not support
block integrity any more. So add it to the whitelist.
This is also a pre-requisite to use block integrity with other dm layer(s)
on top of multipath, such as kpartx partitions (dm-linear) or LVM.
Also, bump target version to reflect this fix.

commit 1a087f032111a88e826877449dfb93ceb22b78b9 upstream.
When I debug a kernel crash issue in funcitonfs, found ffs_data.ref
overflowed, While functionfs is unmounting, ffs_data is put twice.
Commit 43938613c6fd ("drivers, usb: convert ffs_data.ref from atomic_t to
refcount_t") can avoid refcount overflow, but that is risk some situations.
So no need put ffs data in ffs_fs_kill_sb, already put in ffs_data_closed.
The issue can be reproduced in Mediatek mt6763 SoC, ffs for ADB device.
KASAN enabled configuration reports use-after-free errro.

From: H.J. Lu <[email protected]>
commit b21ebf2fb4cde1618915a97cc773e287ff49173e upstream.
On i386, there are 2 types of PLTs, PIC and non-PIC. PIE and shared
objects must use PIC PLT. To use PIC PLT, you need to load
_GLOBAL_OFFSET_TABLE_ into EBX first. There is no need for that on
x86-64 since x86-64 uses PC-relative PLT.
On x86-64, for 32-bit PC-relative branches, we can generate PLT32
relocation, instead of PC32 relocation, which can also be used as
a marker for 32-bit PC-relative branches. Linker can always reduce
PLT32 relocation to PC32 if function is defined locally. Local
functions should use PC32 relocation. As far as Linux kernel is
concerned, R_X86_64_PLT32 can be treated the same as R_X86_64_PC32
since Linux kernel doesn't use PLT.
R_X86_64_PLT32 for 32-bit PC-relative branches has been enabled in
binutils master branch which will become binutils 2.31.
[ hjl is working on having better documentation on this all, but a few
more notes from him:
"PLT32 relocation is used as marker for PC-relative branches. Because
of EBX, it looks odd to generate PLT32 relocation on i386 when EBX
doesn't have GOT.
As for symbol resolution, PLT32 and PC32 relocations are almost
interchangeable. But when linker sees PLT32 relocation against a
protected symbol, it can resolved locally at link-time since it is
used on a branch instruction. Linker can't do that for PC32
relocation"
but for the kernel use, the two are basically the same, and this
commit gets things building and working with the current binutils
master - Linus ]

commit 9c2c2e62df3fa30fb13fbeb7512a4eede729383b upstream.
commit f5e64032a799 ("net: phy: fix resume handling") changes the
locking semantics for phy_resume() such that the caller now needs to
hold the phy mutex. Not all call sites were adopted to this new
semantic, resulting in warnings from the added
WARN_ON(!mutex_is_locked(&phydev->lock)). Rather than change the
semantics, add a __phy_resume() and restore the old behavior of
phy_resume().

commit cb88a0588717ba6c756cb5972d75766b273a6817 upstream.
Corsair Strafe RGB keyboard does not respond to usb control messages
sometimes and hence generates timeouts.
Commit de3af5bf259d ("usb: quirks: add delay init quirk for Corsair
Strafe RGB keyboard") tried to fix those timeouts by adding
USB_QUIRK_DELAY_INIT.
Unfortunately, even with this quirk timeouts of usb_control_msg()
can still be seen, but with a lower frequency (approx. 1 out of 15):
[ 29.103520] usb 1-8: string descriptor 0 read error: -110
[ 34.363097] usb 1-8: can't set config #1, error -110
Adding further delays to different locations where usb control
messages are issued just moves the timeouts to other locations,
e.g.:
[ 35.400533] usbhid 1-8:1.0: can't add hid device: -110
[ 35.401014] usbhid: probe of 1-8:1.0 failed with error -110
The only way to reliably avoid those issues is having a pause after
each usb control message. In approx. 200 boot cycles no more timeouts
were seen.
Addionaly, keep USB_QUIRK_DELAY_INIT as it turned out to be necessary
to have the delay in hub_port_connect() after hub_port_init().
The overall boot time seems not to be influenced by these additional
delays, even on fast machines and lightweight distributions.

commit df3334c223a033f562645712e832ca4cbb326bbf upstream.
Currently the driver attempts to spin lock on udc->lock before a NULL
pointer check is performed on udc, hence there is a potential null
pointer dereference on udc->lock. Fix this by moving the null check
on udc before the lock occurs.

ashmem_mutex create a chain of dependencies like so:
(1)
mmap syscall ->
mmap_sem -> (acquired)
ashmem_mmap
ashmem_mutex (try to acquire)
(block)
(2)
llseek syscall ->
ashmem_llseek ->
ashmem_mutex -> (acquired)
inode_lock ->
inode->i_rwsem (try to acquire)
(block)
(3)
getdents ->
iterate_dir ->
inode_lock ->
inode->i_rwsem (acquired)
copy_to_user ->
mmap_sem (try to acquire)
There is a lock ordering created between mmap_sem and inode->i_rwsem
causing a lockdep splat [2] during a syzcaller test, this patch fixes
the issue by unlocking the mutex earlier. Functionally that's Ok since
we don't need to protect vfs_llseek.

From: Russell King <[email protected]>
[ Upstream commit f5e64032a799d4f54decc7eb6aafcdffb67f9ad9 ]
When a PHY has the BMCR_PDOWN bit set, it may decide to ignore writes
to other registers, or reset the registers to power-on defaults.
Micrel PHYs do this for their interrupt registers.
The current structure of phylib tries to enable interrupts before
resuming (and releasing) the BMCR_PDOWN bit. This fails, causing
Micrel PHYs to stop working after a suspend/resume sequence if they
are using interrupts.
Fix this by ensuring that the PHY driver resume methods do not take
the phydev->lock mutex themselves, but the callers of phy_resume()
take that lock. This then allows us to move the call to phy_resume()
before we enable interrupts in phy_start().

Ok, that sucked, let's try this again...
-rc3 is out, and this time it at least passed _my_ build tests:

Okay let me grab your tree and cherry-pick all that is required and send

This actually needs commit ffb009b24388b896d9ca8b54e39a879302142518
("clk: ti: convert retry_init param to use void data type") as
prerequisite, otherwise it fails building.

I think these are the patches that need to be picked for this to work/compile:
2c6929d2ea70 dmaengine: s3c24xx-dma: Use vchan_terminate_vdesc() instead of desc_free
3ee7e42f3c9b dmaengine: k3dma: Use vchan_terminate_vdesc() instead of desc_free
397c59bce6cb dmaengine: img-mdc-dma: Use vchan_terminate_vdesc() instead of desc_free
47d71bc75d07 dmaengine: amba-pl08x: Use vchan_terminate_vdesc() instead of desc_free
f0dd52c85d61 dmaengine: dma-jz4780: Use vchan_terminate_vdesc() instead of desc_free
de92436ac40f dmaengine: bcm2835-dma: Use vchan_terminate_vdesc() instead of desc_free
174334bcd9f8 dmaengine: edma: Use vchan_terminate_vdesc() instead of desc_free
b1faf0f564ff dmaengine: omap-dma: Use vchan_terminate_vdesc() instead of desc_free
1c7f072d94e8 dmaengine: virt-dma: Support for race free transfer termination
6af149d2b142 dmaengine: virt-dma: Add helper to free/reuse a descriptor
Most probably we missed the 6af149d2b142 and that caused the build failures.

Yeah that looks to be the case, I have pushed out topic/dmaengine_stable
after cherry-picking the old topic branch for these. My build tests passed,
waiting for Fenguuang's bit to bless it and send :)

Thanks, I'll just drop this patch from the trees now, as that seems to
make more sense.
Sasha, if you want to pick both of these up for your next round of
patches to submit, that's fine.

As reported, arm32 build failed and so tests did not run. No regressions on
arm64 or x86_64.
There are two 'regressions' listed below which are not regressions.
reuseport_bpf is a test issue that's fixed in mainline kselftest, which we'll
pick up when 4.16 is released. sigreturn_64 is an intermittent failure that
we've been seeing on qemu only. It works fine on real hardware.

Any chance to get the k10temp change for Threadripper 1900X offset
reporting included [https://patchwork.kernel.org/patch/10175457/]?

As Peter pointed out we missed 6af149d2b142.
Here is the complete list of patches:
3ee7e42f3c9b dmaengine: k3dma: Use vchan_terminate_vdesc() instead of desc_free
397c59bce6cb dmaengine: img-mdc-dma: Use vchan_terminate_vdesc() instead of desc_free
47d71bc75d07 dmaengine: amba-pl08x: Use vchan_terminate_vdesc() instead of desc_free
f0dd52c85d61 dmaengine: dma-jz4780: Use vchan_terminate_vdesc() instead of desc_free
de92436ac40f dmaengine: bcm2835-dma: Use vchan_terminate_vdesc() instead of desc_free
174334bcd9f8 dmaengine: edma: Use vchan_terminate_vdesc() instead of desc_free
b1faf0f564ff dmaengine: omap-dma: Use vchan_terminate_vdesc() instead of desc_free
1c7f072d94e8 dmaengine: virt-dma: Support for race free transfer termination
6af149d2b142 dmaengine: virt-dma: Add helper to free/reuse a descriptor
Last time we missed 6af149d2b142.
Also I have got a 4.9 break report which is also due to missing 6af149d2b142
and 1c7f072d94e8
Thanks

Nope, the offset for 1900X is not available in 4.15, I've had to
manually patch all systems otherwise monitoring complains they idle at 53C.

And if you ant it to work in 4.14 longterm, you want the series:

I'd like an ack from the hwmon maintainer before adding all of those, as
it really feels like a "backport new hardware support" type of request
that is a bit bigger than a normal "add some new device ids and quirks".

That is why I did not request it. It is ok with me if you are willing to
accept it, though.
