ASoC: rt5682: Avoid the unexpected IRQ event during going to suspend
When the system suspends, the codec driver will set SAR to
power saving mode if a headset is plugged in.
There is a chance to generate an unexpected IRQ, and leads to
issues after resuming such as noise from OMTP type headsets.

ASoC: rt1011: revert 'I2S Reference' to SOC_ENUM_EXT
Revert 'I2S Reference' to SOC_ENUM_EXT because the settings are specific
for some platforms, the default setting for 'I2S Reference' does nothing,
only some SoC platform need to configure it.
Previous 'I2S Reference' in SOC_ENUM format only toggles one bit of
RT1011_TDM1_SET_1 register, which isn't enough for specific platform.

32a370abf1 net,lsm,selinux: revert the security_sctp_assoc_established() hook
This patch reverts two prior patches, e7310c9402
("security: implement sctp_assoc_established hook in selinux") and
7c2ef0240e ("security: add sctp_assoc_established hook"), which
create the security_sctp_assoc_established() LSM hook and provide a
SELinux implementation.  Unfortunately these two patches were merged
without proper review (the Reviewed-by and Tested-by tags from
Richard Haines were for previous revisions of these patches that
were significantly different) and there are outstanding objections
from the SELinux maintainers regarding these patches.

Work is currently ongoing to correct the problems identified in the
reverted patches, as well as others that have come up during review,
but it is unclear at this point in time when that work will be ready
for inclusion in the mainline kernel.  In the interest of not keeping
objectionable code in the kernel for multiple weeks, and potentially
a kernel release, we are reverting the two problematic patches.

b637108a40 blk-mq: fix filesystem I/O request allocation
submit_bio_checks() may update bio->bi_opf, so we have to initialize
blk_mq_alloc_data.cmd_flags with bio->bi_opf after submit_bio_checks()
returns when allocating new request.

In case of using cached request, fallback to allocate new request if
cached rq isn't compatible with the incoming bio, otherwise change
rq->cmd_flags with incoming bio->bi_opf.

10a20b34d7 of/irq: Don't ignore interrupt-controller when interrupt-map failed
Since 0412841812 ("of/irq: Allow matching of an interrupt-map local
to an interrupt controller"), the irq code favors using an interrupt-map
over a interrupt-controller property if both are available, while the
earlier behaviour was to ignore the interrupt-map altogether.

However, we now end-up with the opposite behaviour, which is to
ignore the interrupt-controller property even if the interrupt-map
fails to match its input. This new behaviour breaks the AmigaOne
X1000 machine, which ships with an extremely "creative" (read:
broken) device tree.

Fix this by allowing the interrupt-controller property to be selected
when interrupt-map fails to match anything.

69ea463021 irqchip/sifive-plic: Fixup EOI failed when masked
When using "devm_request_threaded_irq(,,,,IRQF_ONESHOT,,)" in a driver,
only the first interrupt is handled, and following interrupts are never
delivered (initially reported in [1]).

That's because the RISC-V PLIC cannot EOI masked interrupts, as explained
in the description of Interrupt Completion in the PLIC spec [2]:

<quote>
The PLIC signals it has completed executing an interrupt handler by
writing the interrupt ID it received from the claim to the claim/complete
register. The PLIC does not check whether the completion ID is the same
as the last claim ID for that target. If the completion ID does not match
an interrupt source that *is currently enabled* for the target, the
completion is silently ignored.
</quote>

Re-enable the interrupt before completion if it has been masked during
the handling, and remask it afterwards.

418ace9992 ARM: 9156/1: drop cc-option fallbacks for architecture selection
Naresh and Antonio ran into a build failure with latest Debian
armhf compilers, with lots of output like

 tmp/ccY3nOAs.s:2215: Error: selected processor does not support `cpsid i' in ARM mode

As it turns out, $(cc-option) fails early here when the FPU is not
selected before CPU architecture is selected, as the compiler
option check runs before enabling -msoft-float, which causes
a problem when testing a target architecture level without an FPU:

cc1: error: '-mfloat-abi=hard': selected architecture lacks an FPU

Passing e.g. -march=armv6k+fp in place of -march=armv6k would avoid this
issue, but the fallback logic is already broken because all supported
compilers (gcc-5 and higher) are much more recent than these options,
and building with -march=armv5t as a fallback no longer works.

The best way forward that I see is to just remove all the checks, which
also has the nice side-effect of slightly improving the startup time for
'make'.

The -mtune=marvell-f option was apparently never supported by any mainline
compiler, and the custom Codesourcery gcc build that did support is
now too old to build kernels, so just use -mtune=xscale unconditionally
for those.

This should be safe to apply on all stable kernels, and will be required
in order to keep building them with gcc-11 and higher.

0d08e7bf0d ARM: 9155/1: fix early early_iounmap()
Currently __set_fixmap() bails out with a warning when called in early boot
from early_iounmap(). Fix it, and while at it, make the comment a bit easier
to understand.

==================================================================

Bio will be checked at beginning of submit_bio_noacct(). If bio needs
to be throttled, it will start the timer and stop submit bio directly.
Bio will submit in blk_throtl_dispatch_work_fn() when the timer expires.
But in the current process, if bio is throttled, it will still set bio
issue->value by blkcg_bio_issue_init(). This is redundant and may cause
the above use-after-free.

Use the same cleanup code independent of whether the cgroup to be
uncharged and unref'd is the source or the destination cgroup.  Use a
bool to track whether the destination cgroup has been charged, which also
fixes a bug in the error case: the destination cgroup must be uncharged
only if it does not match the source.

Commit 2d3de197a8 ("ARM: dts: arm: Update ICST clock nodes 'reg' and

to register multiple clocks with the same name. Fix this by including

68d16195b6 of: Support using 'mask' in making device bus id
Commit 25b892b583 ("ARM: dts: arm: Update register-bit-led nodes
'reg' and node names") added a 'reg' property to nodes. This change has
the side effect of changing how the kernel generates the device name.
The assumption was a translatable 'reg' address is unique. However, in
the case of the register-bit-led binding (and a few others) that is not
the case. The 'mask' property must also be used in this case to make a
unique device name.
