commit fce7e152ffc8f89d02a80617b16c7aa1527847c8 upstream.
APM states that #GP is raised upon write to MSR_VM_HSAVE_PA when
the supplied address is not page-aligned or is outside of "maximum
supported physical address for this implementation".
page_address_valid() check seems suitable. Also, forcefully page-align
the address when it's written from VMM.

[ Upstream commit 90b7c141132244e8e49a34a4c1e445cce33e07f4 ]
This module's remove path calls del_timer(). However, that function
does not wait until the timer handler finishes. This means that the
timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

psw to redirect a potential program check on the diag instruction.
Restoring of the program check new psw is done in C code behind the
inline asm.
This can be problematic, especially if the function is inlined, since
the compiler can reorder instructions in such a way that a different
instruction, which may result in a program check, might be executed
before the program check new psw has been restored.
To avoid such a scenario move restoring into the inline asm. For
consistency reasons move also saving of the original program check new
psw into the inline asm.

This driver's remove path calls del_timer(). However, that function
does not wait until the timer handler finishes. This means that the
timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

[ Upstream commit d157fca711ad42e75efef3444c83d2e1a17be27a ]
Remove the hack to assign the global console_port variable at probe time.
This assumption that cons->index is -1 is wrong for systems that specify
'console=' in the cmdline (or 'stdout-path' in dts). Hence, on such system
the actual console assignment is ignored, and the first UART that happens
to be probed is used as console instead.
Move the logic to console_setup() and map the console to the correct port
through the array of available ports instead.

This test will require /dev/rtc0, the default RTC device, or one
specified by user to run. Since this default RTC is not guaranteed to
exist on all of the devices, so check its existence first, otherwise
skip this test with the kselftest skip code 4.
Without this patch this test will fail like this on a s390x zVM:
$ selftests: timers: rtcpie
$ /dev/rtc0: No such file or directory
not ok 1 selftests: timers: rtcpie # exit=22
With this patch:
$ selftests: timers: rtcpie
$ Default RTC /dev/rtc0 does not exist. Test Skipped!
not ok 9 selftests: timers: rtcpie # SKIP
Fixed up change log so "With this patch" text doesn't get dropped.

When *RSTOR from user memory raises an exception, there is no way to
differentiate them. That's bad because it forces the slow path even when
the failure was not a fault. If the operation raised eg. #GP then going
through the slow path is pointless.
Use _ASM_EXTABLE_FAULT() which stores the trap number and let the exception
fixup return the negated trap number as error.
This allows to separate the fast path and let it handle faults directly and
avoid the slow path for all other exceptions.

[ Upstream commit 2c484419efc09e7234c667aa72698cb79ba8d8ed ]
lz4 compatible decompressor is simple. The format is underspecified and
relies on EOF notification to determine when to stop. Initramfs buffer
format[1] explicitly states that it can have arbitrary number of zero
padding. Thus when operating without a fill function, be extra careful to
ensure that sizes less than 4, or apperantly empty chunksizes are treated
as EOF.
To test this I have created two cpio initrds, first a normal one,
main.cpio. And second one with just a single /test-file with content
"second" second.cpio. Then i compressed both of them with gzip, and with
lz4 -l. Then I created a padding of 4 bytes (dd if=/dev/zero of=pad4 bs=1
count=4). To create four testcase initrds:
1) main.cpio.gzip + extra.cpio.gzip = pad0.gzip
2) main.cpio.lz4 + extra.cpio.lz4 = pad0.lz4
3) main.cpio.gzip + pad4 + extra.cpio.gzip = pad4.gzip
4) main.cpio.lz4 + pad4 + extra.cpio.lz4 = pad4.lz4
The pad4 test-cases replicate the initrd load by grub, as it pads and
aligns every initrd it loads.
All of the above boot, however /test-file was not accessible in the initrd
for the testcase #4, as decoding in lz4 decompressor failed. Also an
error message printed which usually is harmless.
Whith a patched kernel, all of the above testcases now pass, and
/test-file is accessible.
This fixes lz4 initrd decompress warning on every boot with grub. And
more importantly this fixes inability to load multiple lz4 compressed
initrds with grub. This patch has been shipping in Ubuntu kernels since
January 2021.

[ Upstream commit cb011044e34c293e139570ce5c01aed66a34345c ]
This was already attempted to fix via 1fccb73011ea: If the BIOS did not
enable TCO SMIs, the timer definitely needs to trigger twice in order to
cause a reboot. If TCO SMIs are on, as well as SMIs in general, we can
continue to assume that the BIOS will perform a reboot on the first
timeout.
QEMU with its ICH9 and related BIOS falls into the former category,
currently taking twice the configured timeout in order to reboot the
machine. For iTCO version that fall under turn_SMI_watchdog_clear_off,
this is also true and was currently only addressed for v1, irrespective
of the turn_SMI_watchdog_clear_off value.

Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage

The checks for page->mapping are odd, as set_page_dirty is an
address_space operation, and I don't see where it would be called on a
non-pagecache page.
The warning about the page lock also seems bogus. The comment over
set_page_dirty() says that it can be called without the page lock in
some rare cases. I don't think we want to warn if that's the case.

[ Upstream commit dcdb4d904b4bd3078fe8d4d24b1658560d6078ef ]
3 cases of kobj leak, which causes memory leak:
kobj_type must have release() method to free memory from release
callback. Don't need NULL default_attrs to init kobj.
sysfs files created under kobj_status should be removed with kobj_status
as parent kobject.
Remove queue sysfs files when releasing queue from process MMU notifier
release callback.

"utf16s_to_utf8s(..., buf, PAGE_SIZE)" puts up to PAGE_SIZE bytes into
"buf" and returns the number of bytes it actually put there. If it wrote
PAGE_SIZE bytes, the newline added by dsm_label_utf16s_to_utf8s() would
overrun "buf".
Reduce the size available for utf16s_to_utf8s() to use so there is always
space for the newline.

[ Upstream commit 540540d06e9d9b3769b46d88def90f7e7c002322 ]
Until now no compiler supported an attribute to disable coverage
instrumentation as used by KCOV.
To work around this limitation on x86, noinstr functions have their
coverage instrumentation turned into nops by objtool. However, this
solution doesn't scale automatically to other architectures, such as
arm64, which are migrating to use the generic entry code.
Clang [1] and GCC [2] have added support for the attribute recently.
[1] https://github.com/llvm/llvm-project/commit/280333021e9550d80f5c1152a34e33e81df1e178
[2] https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=cec4d4a6782c9bd8d071839c50a239c49caca689
The changes will appear in Clang 13 and GCC 12.
Add __no_sanitize_coverage for both compilers, and add it to noinstr.
Note: In the Clang case, __has_feature(coverage_sanitizer) is only true if
the feature is enabled, and therefore we do not require an additional
defined(CONFIG_KCOV) (like in the GCC case where __has_attribute(..) is
always true) to avoid adding redundant attributes to functions if KCOV is
off. That being said, compilers that support the attribute will not
generate errors/warnings if the attribute is redundantly used; however,
where possible let's avoid it as it reduces preprocessed code size and
associated compile-time overheads.

From: Stephan Gerhold <[email protected]>
[ Upstream commit f3076cd8d1d5fa64b5e1fa5affc045c2fc123baa ]
The fuel gauge in the RT5033 PMIC has its own I2C bus and interrupt
line. Therefore, it is not actually part of the RT5033 MFD and needs
its own of_match_table to probe properly.
Also, given that it's independent of the MFD, there is actually
no need to make the Kconfig depend on MFD_RT5033. Although the driver
uses the shared <linux/mfd/rt5033.h> header, there is no compile
or runtime dependency on the RT5033 MFD driver.

On removing the device, any work item (hv_pci_devices_present() or
hv_pci_eject_device()) scheduled on workqueue hbus->wq may still be running
and race with hv_pci_remove().
This can happen because the host may send PCI_EJECT or PCI_BUS_RELATIONS(2)
and decide to rescind the channel immediately after that.
Fix this by flushing/destroying the workqueue of hbus before doing hbus remove.

not set in the xstate header is only correct for the legacy area, but
not for the extended features area because when XSAVES is in use then
init_fpstate is in compacted form which means the xstate offsets which
are used to copy from init_fpstate are not valid.
Fortunately, this is not a real problem today because all extended
features in use have an all-zeros init state, but it is wrong
nevertheless and with a potentially dynamically sized init_fpstate this
would result in an access outside of the init_fpstate.
Fix this by keeping track of the last copied state in the target buffer and
explicitly zero it when there is a feature or alignment gap.
Use the compacted offset when accessing the extended feature space in
init_fpstate.
As this is not a functional issue on older kernels this is intentionally
not tagged for stable.

[ Upstream commit b64210f2f7c11c757432ba3701d88241b2b98fb1 ]
If an i2c client receives an interrupt during reboot or shutdown it may
be too late to service it by making an i2c transaction on the bus
because the i2c controller has already been shutdown. This can lead to
system hangs if the i2c controller tries to make a transfer that is
doomed to fail because the access to the i2c pins is already shut down,
or an iommu translation has been torn down so i2c controller register
access doesn't work.
Let's simply disable the irq if there isn't a shutdown callback for an
i2c client when there is an irq associated with the device. This will
make sure that irqs don't come in later than the time that we can handle
it. We don't do this if the i2c client device already has a shutdown
callback because presumably they're doing the right thing and quieting
the device so irqs don't come in after the shutdown callback returns.

[ Upstream commit 54b909436ede47e0ee07f1765da27ec2efa41e84 ]
The scnprintf() function silently truncates the printf() and returns
the number bytes that it was able to copy (not counting the NUL
terminator). Thus, the highest value it can return here is
"NAME_SIZE - 1" and the overflow check is dead code. Fix this by
using the snprintf() function which returns the number of bytes that
would have been copied if there was enough space and changing the
condition from "> NAME_SIZE" to ">= NAME_SIZE".

A consumer is expected to disable a PWM before calling pwm_put(). And if
they didn't there is hopefully a good reason (or the consumer needs
fixing). Also if disabling an enabled PWM was the right thing to do,
this should better be done in the framework instead of in each low level
driver.
So drop the hardware modification from the .remove() callback.

[ Upstream commit aa95edf309ef31e2df4a37ebf0e5c2ca2a6772ab ]
If we have multiple outstanding layoutget requests, the current code to
update the layout barrier assumes that the outstanding layout stateids
are updated in order. That's not necessarily the case.
Instead of using the value of lo->plh_outstanding as a guesstimate for
the window of values we need to accept, just wait to update the window
until we're processing the last one. The intention here is just to
ensure that we don't process 2^31 seqid updates without also updating
the barrier.

Fix copy paste bug assigning umem1 size to umem2 and umem3. The issue
was discovered when trying to use a 1:1 MR that covers the entire
address space where firmware complained that provided sizes are not
large enough. 1:1 MRs are required to support virtio_vdpa.

[ Upstream commit 5a2f966d0f3fa0ef6dada7ab9eda74cacee96b8a ]
It's unsafe to operate a vq from multiple threads.
Unfortunately this is exactly what we do when invoking
clean tx poll from rx napi.
Same happens with napi-tx even without the
opportunistic cleaning from the receive interrupt: that races
with processing the vq in start_xmit.
As a fix move everything that deals with the vq to under tx lock.

A consumer is expected to disable a PWM before calling pwm_put(). And if
they didn't there is hopefully a good reason (or the consumer needs
fixing). Also if disabling an enabled PWM was the right thing to do,
this should better be done in the framework instead of in each low level
driver.
So drop the hardware modification from the .remove() callback.

[ Upstream commit 3e1493f46390618ea78607cb30c58fc19e2a5035 ]
When a task wakes up on an idle rq, uclamp_rq_util_with() would max
aggregate with rq value. But since there is no task enqueued yet, the
values are stale based on the last task that was running. When the new
task actually wakes up and enqueued, then the rq uclamp values should
reflect that of the newly woken up task effective uclamp values.
This is a problem particularly for uclamp_max because it default to
1024. If a task p with uclamp_max = 512 wakes up, then max aggregation
would ignore the capping that should apply when this task is enqueued,
which is wrong.
Fix that by ignoring max aggregation if the rq is idle since in that
case the effective uclamp value of the rq will be the ones of the task
that will wake up.

From: Pali Rohár <[email protected]>
[ Upstream commit 2eab59cf0d2036a5a9e264f719b71c21ccf679c2 ]
When Marvell's rWTM firmware, which does not support the GET_RANDOM
command, is used, kernel prints an error message
hwrng: no data available
every 10 seconds.
Fail probing of this driver if the rWTM firmware does not support the
GET_RANDOM command.

[ Upstream commit 78b4b165280d3d70e7a217599f0c06a4c0bb11f9 ]
With [1] USB4 target-module node got defined in dra74x.dtsi file.
However, the earlier definition in [2] was not removed, and this
duplication of the target module is causing boot failure on dra74
variant boards - dra7-evm, dra76-evm.
USB4 is only present in DRA74x variants, so keeping the entry in
dra74x.dtsi and removing it from the top level interconnect hierarchy
dra7-l4.dtsi file. This change makes the USB4 target module no longer
visible to AM5718, DRA71x and DRA72x so removing references to it in
their respective dts files.
[1]: commit c7b72abca61ec ("ARM: OMAP2+: Drop legacy platform data for
dra7 dwc3")
[2]: commit 549fce068a311 ("ARM: dts: dra7: Add l4 interconnect
hierarchy and ti-sysc data")

[ Upstream commit cddc40f5617e53f97ef019d5b29c1bd6cbb031ec ]
My series to clean up the unaligned access implementation
across architectures caused some mips randconfig builds to
fail with:
mips64-linux-ld: arch/mips/boot/compressed/decompress.o: in function `decompress_kernel':
decompress.c:(.text.decompress_kernel+0x54): undefined reference to `__bswapsi2'
It turns out that this problem has already been fixed for the XZ
decompressor but now it also shows up in (at least) LZO and LZ4. From my
analysis I concluded that the compiler could always have emitted those
calls, but the different implementation allowed it to make otherwise
better decisions about not inlining the byteswap, which results in the
link error when the out-of-line code is missing.
While it could be addressed by adding it to the two decompressor
implementations that are known to be affected, but as this only adds
112 bytes to the kernel, the safer choice is to always add them.
Fixes: c50ec6787536 ("MIPS: zboot: Fix the build with XZ compression on older GCC versions")

[ Upstream commit 9e667624c291753b8a5128f620f493d0b5226063 ]
It turns out that jump_label_text_reserved() was reporting __init text
as being reserved past the time when the __init text was freed and
re-used.
For a long time, this resulted in, at worst, not being able to kprobe
text that happened to land at the re-used address. However a recent
commit e7bf1ba97afd ("jump_label, x86: Emit short JMP") made it a
fatal mistake because it now needs to read the instruction in order to
determine the conflict -- an instruction that's no longer there.

[ Upstream commit 44b615ac9fab16d1552cd8360454077d411e3c35 ]
Tag the highest "Power Optimized" (1.5 GHz) Cortex-A57 operating point
table entries for the RZ/G2M, R-Car M3-W and M3-W+ SoCs with the
"opp-suspend" property. This makes sure the system will enter suspend
in the same performance state as it will be resumed by the firmware
later, avoiding state inconsistencies after resume.
Based on a patch for R-Car M3-W in the BSP by Takeshi Kihara
<[email protected]>.

2.30.2
From: Chang S. Bae <[email protected]>
[ Upstream commit 2beb4a53fc3f1081cedc1c1a198c7f56cc4fc60c ]
The kernel pushes context on to the userspace stack to prepare for the
user's signal handler. When the user has supplied an alternate signal
stack, via sigaltstack(2), it is easy for the kernel to verify that the
stack size is sufficient for the current hardware context.
Check if writing the hardware context to the alternate stack will exceed
it's size. If yes, then instead of corrupting user-data and proceeding with
the original signal handler, an immediate SIGSEGV signal is delivered.
Refactor the stack pointer check code from on_sig_stack() and use the new
helper.
While the kernel allows new source code to discover and use a sufficient
alternate signal stack size, this check is still necessary to protect
binaries with insufficient alternate signal stack size from data
corruption.

tegra_pcie_ep_raise_msi_irq() shifted a signed 32-bit value left by 31

The legacy PCI interrupt lines need to be enabled using PCIE_APP_IRNEN bits
13 (INTA), 14 (INTB), 15 (INTC) and 16 (INTD). The old code however was
taking (for example) "13" as raw value instead of taking BIT(13). Define
the legacy PCI interrupt bits using the BIT() macro and then use these in
PCIE_APP_IRN_INT.

[ Upstream commit 3cf5f7ab230e2b886e493c7a8449ed50e29d2b98 ]
An IRQ handler may be called at any time after it is registered, so
anything it relies on must be ready before registration.
rockchip_pcie_subsys_irq_handler() and rockchip_pcie_client_irq_handler()
read registers in the PCIe controller, but we registered them before
turning on clocks to the controller. If either is called before the clocks
are turned on, the register reads fail and the machine hangs.
Similarly, rockchip_pcie_legacy_int_handler() uses rockchip->irq_domain,
but we installed it before initializing irq_domain.
Register IRQ handlers after their data structures are initialized and
clocks are enabled.
Found by enabling CONFIG_DEBUG_SHIRQ, which calls the IRQ handler when it
is being unregistered. An error during the probe path might cause this
unregistration and IRQ handler execution before the device or data
structure init has finished.

As marcosfrm reported in bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=213089
Initramfs generators rely on "pre" softdeps (and "depends") to include
additional required modules.
F2FS does not declare "pre: crc32" softdep. Then every generator (dracut,
mkinitcpio...) has to maintain a hardcoded list for this purpose.
Hence let's use MODULE_SOFTDEP("pre: crc32") in f2fs code.

[ Upstream commit bd5431b2f9b30a70f6ed964dd5ee9a6d1c397c06 ]
Although the schematics of Pine A64-LTS and SoPine Baseboard shows both
the RX and TX internal delay are enabled, they're using the same broken
RTL8211E chip batch with Pine A64+, so they should use TXID instead, not
ID.
In addition, by checking the real components soldered on both a SoPine
Baseboard and a Pine A64-LTS, RX delay is not enabled (GR69 soldered and
GR70 NC) despite the schematics says it's enabled. It's a common
situation for Pine64 boards that the NC information on schematics is not
the same with the board.
So the RGMII delay mode should be TXID on these boards.

commit 281e468446994a7672733af2bf941f4110d4a895 upstream.
This patch fixes a trivial mistake that I made in the previous attempt
in fixing the null bridge issue. The branch condition is inverted and we
should call alcor_pci_find_cap_offset() only if bridge is not null.

[ Upstream commit 2dc0a201d0f59e6818ef443609f0850a32910844 ]
The interrupt affinity scheme used by this driver is incompatible with
multi-MSI as it implies moving the doorbell address to that of another MSI
group. This isn't possible for multi-MSI, as all the MSIs must have the
same doorbell address. As such it is restricted to systems with a single
CPU.

The Dell Vostro 3350 ACPI video-bus device reports spurious
ACPI_VIDEO_NOTIFY_CYCLE events resulting in spurious KEY_SWITCHVIDEOMODE
events being reported to userspace (and causing trouble there).
Add a quirk setting the report_key_events mask to
REPORT_BRIGHTNESS_KEY_EVENTS so that the ACPI_VIDEO_NOTIFY_CYCLE
events will be ignored, while still reporting brightness up/down
hotkey-presses to userspace normally.

[ Upstream commit 1bc6ea31cb41d50302a3c9b401964cf0a88d41f9 ]
The .remove() callback disables clocks that were not enabled in
.probe(). So just probing and then unbinding the driver results in a clk
enable imbalance.
So just drop the call to disable the clocks. (Which BTW was also in the
wrong order because the call makes the PWM unfunctional and so should
have come only after pwmchip_remove()).

MODULE_DEVICE_TABLE is used to extract the device information out of the
driver and builds a table when being compiled. If using this macro,
kernel can find the driver if available when the device is plugged in,
and then loads that driver and initializes the device.

From: Martin Fäcknitz <[email protected]>
[ Upstream commit 47ce8527fbba145a7723685bc9a27d9855e06491 ]
Accessing raw timers (currently only CLOCK_MONOTONIC_RAW) through VDSO
doesn't return the correct time when using the GIC as clock source.
The address of the GIC mapped page is in this case not calculated
correctly. The GIC mapped page is calculated from the VDSO data by
subtracting PAGE_SIZE:
void *get_gic(const struct vdso_data *data) {
return (void __iomem *)data - PAGE_SIZE;
}
However, the data pointer is not page aligned for raw clock sources.
This is because the VDSO data for raw clock sources (CS_RAW = 1) is
stored after the VDSO data for coarse clock sources (CS_HRES_COARSE = 0).
Therefore, only the VDSO data for CS_HRES_COARSE is page aligned:
+--------------------+
| |
| vd[CS_RAW] | ---+
| vd[CS_HRES_COARSE] | |
+--------------------+ | -PAGE_SIZE
| | |
| GIC mapped page | <--+
| |
+--------------------+
When __arch_get_hw_counter() is called with &vd[CS_RAW], get_gic returns
the wrong address (somewhere inside the GIC mapped page). The GIC counter
values are not returned which results in an invalid time.

[ Upstream commit 892ba7f18621a02af4428c58d97451f64685dba4 ]
Current 'perf report' fails to process a pipe input when --task or
--stat options are used. This is because they reset all the tool
callbacks and fails to find a matching event for a sample.
When pipe input is used, the event info is passed via ATTR records so it
needs to handle that operation. Otherwise the following error occurs.
Note, -14 (= -EFAULT) comes from evlist__parse_sample():

Patch series "hexagon: Fix build error with CONFIG_STACKDEPOT and select CONFIG_ARCH_WANT_LD_ORPHAN_WARN".
This series fixes an error with ARCH=hexagon that was pointed out by the
patch "mm/slub: use stackdepot to save stack trace in objects".
The first patch fixes that error by handling the '.irqentry.text' and
'.softirqentry.text' sections.
The second patch switches Hexagon over to the common DISCARDS macro, which
should have been done when Hexagon was merged into the tree to match
commit 023bf6f1b8bf ("linker script: unify usage of discard definition").
The third patch selects CONFIG_ARCH_WANT_LD_ORPHAN_WARN so that something
like this does not happen again.
This patch (of 3):
Patch "mm/slub: use stackdepot to save stack trace in objects" in -mm
selects CONFIG_STACKDEPOT when CONFIG_STACKTRACE_SUPPORT is selected and
CONFIG_STACKDEPOT requires IRQENTRY_TEXT and SOFTIRQENTRY_TEXT to be
handled after commit 505a0ef15f96 ("kasan: stackdepot: move
filter_irq_stacks() to stackdepot.c") due to the use of the
__{,soft}irqentry_text_{start,end} section symbols. If those sections are
not handled, the build is broken.

[ Upstream commit 4a67d9b07ac8dce7f1034e0d887f2f4ee00fe118 ]
This patch restricts to configure compress extension as format of:
[filename + '.' + extension]
rather than:
[filename + '.' + extension + (optional: '.' + temp extension)]
in order to avoid to enable compression incorrectly:
1. compress_extension=so
2. touch file.soa
3. touch file.so.tmp

[ Upstream commit 474bc334698df98ce07c890f1898c7e7f389b0c7 ]
When flushing out the unstable file writes as part of a COMMIT call, try
to perform most of of the data writes and waits outside the semaphore.
This means that if the client is sending the COMMIT as part of a memory
reclaim operation, then it can continue performing I/O, with contention
for the lock occurring only once the data sync is finished.

We should indicate that we're not using the HPD pin on this device, per
the binding document. Otherwise if code in the future wants to enable
HPD in the bridge when this property is absent we'll be wasting power
powering hpd when we don't use it on trogdor boards. We didn't notice
this before because the kernel driver blindly disables hpd, but that
won't be true for much longer.

[ Upstream commit 0cb7af474e0dbb2f500c67aa62b6db9fafa74de2 ]
During an async commands execution the Rx buffer length is at first set
to max_msg_sz when the synchronous part of the command is first sent.
However once the synchronous part completes the transport layer waits
for the delayed response which will be processed using the same xfer
descriptor initially allocated. Since synchronous response received at
the end of the xfer will shrink the Rx buffer length to the effective
payload response length, it needs to be reset again.
Raise the Rx buffer length again to max_msg_sz before fetching the
delayed response to ensure full response is read correctly from the
shared memory.

Commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx delay

wrong setting.
Following the example of a900cac3750b ("ARM: dts: sun7i: a20: bananapro:

Rename the external refclk inputs to the SERDES from
dummy_cmn_refclk/dummy_cmn_refclk1 to cmn_refclk/cmn_refclk1
respectively. Also move the external refclk DT nodes outside the
cbass_main DT node. Since in j721e common processor board, only the
cmn_refclk1 is connected to 100MHz clock, fix the clock frequency.

2.30.2
From: Marek Vasut <[email protected]>
[ Upstream commit 1cebcf9932ab76102e8cfc555879574693ba8956 ]
The Microchip LAN8710Ai PHY requires XTAL1/CLKIN external clock to be
enabled when the nRST is toggled according to datasheet Microchip
LAN8710A/LAN8710Ai DS00002164B page 35 section 3.8.5.1 Hardware Reset:
"
A Hardware reset is asserted by driving the nRST input pin low. When
driven, nRST should be held low for the minimum time detailed in
Section 5.5.3, "Power-On nRST & Configuration Strap Timing," on page
59 to ensure a proper transceiver reset. During a Hardware reset, an
external clock must be supplied to the XTAL1/CLKIN signal.
"
This is accidentally fulfilled in the current setup, where ETHCK_K is used
to supply both PHY XTAL1/CLKIN and is also fed back through eth_clk_fb to
supply ETHRX clock of the DWMAC. Hence, the DWMAC enables ETHRX clock,
that has ETHCK_K as parent, so ETHCK_K clock are also enabled, and then
the PHY reset toggles.
However, this is not always the case, e.g. in case the PHY XTAL1/CLKIN
clock are supplied by some other clock source than ETHCK_K or in case
ETHRX clock are not supplied by ETHCK_K. In the later case, ETHCK_K would
be kept disabled, while ETHRX clock would be enabled, so the PHY would
not be receiving XTAL1/CLKIN clock and the reset would fail.
Improve the DT by adding the PHY clock phandle into the PHY node, which
then also requires moving the PHY reset GPIO specifier in the same place
and that then also requires correct PHY reset GPIO timing, so add that
too.
A brief note regarding the timing, the datasheet says the reset should
stay asserted for at least 100uS and software should wait at least 200nS
after deassertion. Set both delays to 500uS which should be plenty.

In case of error, the function device_node_to_regmap() returns
ERR_PTR() and never returns NULL. The NULL test in the return
value check should be replaced with IS_ERR().

The sk_user_data pointer is supposed to be modified only while
holding the write_lock "sk_callback_lock", otherwise
we could race with other threads and crash the kernel.
we can't take the write_lock in nvmet_tcp_state_change()
because it would cause a deadlock, but the release_work queue
will set the pointer to NULL later so we can simply remove
the assignment.

[ Upstream commit bc1c56e9bbe92766d017efb5f0a0c71f80da5570 ]
If an RPC client is created without RPC_CLNT_CREATE_REUSEPORT, it should
not reuse the source port when a TCP connection is re-established.
This is currently implemented by preventing the source port being
recorded after a successful connection (the call to xs_set_srcport()).
However the source port is also recorded after a successful bind in xs_bind().
This may not be needed at all and certainly is not wanted when
RPC_CLNT_CREATE_REUSEPORT wasn't requested.
So avoid that assignment when xprt.reuseport is not set.
With this change, NFSv4.1 and later mounts use a different port number on
each connection. This is helpful with some firewalls which don't cope
well with port reuse.

[ Upstream commit 45677c9aebe926192e59475b35a1ff35ff2d4217 ]
The "no_handler_test" in ebb selftests attempts to read the PMU
registers twice via helper function "dump_ebb_state". First dump is
just before closing of event and the second invocation is done after
closing of the event. The original intention of second
dump_ebb_state was to dump the state of registers at the end of
the test when the counters are frozen. But this will be achieved
with the first call itself since sample period is set to low value
and PMU will be frozen by then. Hence patch removes the
dump which was done before closing of the event.

Sorry about that.
Kishon: You might want to send the fixes separately to stable for fixup.

So I understand we want this for mainline, but AFAICT 5.10 does not
have 9a6944fee68e ("tracing: Add a verifier to check string pointers
for trace events") commit, so this does not fix any bug and removal of
tracepoints can be surprising.

Thanks for pointing this out. I get so many stable patches, I don't
have time to look at all of them.
Greg, I don't think this should be backported. The verifier code had a
bug in it that broke the '%.*s' formats. This patch removed the good
code because of the broken code.
See eb01f5353bdaa ("tracing: Handle %.*s in trace_check_vprintf()")

Uh, yes, I'll drop it. Thanks for catching this!
