7051efc07d dt-bindings: apple,aic: Fix required item "apple,fiq-index" in affinity description
commit da3b1c294d upstream.

The required list used "fiq-index" instead of "apple,fiq-index"
described as property and used in the dts. Add the missing "apple,"
prefix.

65d9835668 dt-bindings: iio: gyroscope: bosch,bmg160: correct number of pins
[ Upstream commit 767470209c ]

BMG160 has two interrupt pins to which interrupts can be freely mapped.
Correct the schema to express such case and fix warnings like:

  qcom/msm8916-alcatel-idol347.dtb: gyroscope@68: interrupts: [[97, 1], [98, 1]] is too long

However the basic issue still persists - the interrupts should come in a

31e75db892 arm64: errata: add detection for AMEVCNTR01 incrementing incorrectly
[ Upstream commit e89d120c4b ]

The AMU counter AMEVCNTR01 (constant counter) should increment at the same
rate as the system counter. On affected Cortex-A510 cores, AMEVCNTR01
increments incorrectly giving a significantly higher output value. This
results in inaccurate task scheduler utilization tracking and incorrect
feedback on CPU frequency.

Work around this problem by returning 0 when reading the affected counter
in key locations that results in disabling all users of this counter from
using it either for frequency invariance or as FFH reference counter. This
effect is the same to firmware disabling affected counters.

Details on how the two features are affected by this erratum:

 - AMU counters will not be used for frequency invariance for affected
   CPUs and CPUs in the same cpufreq policy. AMUs can still be used for
   frequency invariance for unaffected CPUs in the system. Although
   unlikely, if no alternative method can be found to support frequency
   invariance for affected CPUs (cpufreq based or solution based on
   platform counters) frequency invariance will be disabled. Please check
   the chapter on frequency invariance at
   Documentation/scheduler/sched-capacity.rst for details of its effect.

 - Given that FFH can be used to fetch either the core or constant counter
   values, restrictions are lifted regarding any of these counters
   returning a valid (!0) value. Therefore FFH is considered supported
   if there is a least one CPU that support AMUs, independent of any
   counters being disabled or affected by this erratum. Clarifying
   comments are now added to the cpc_ffh_supported(), cpu_read_constcnt()
   and cpu_read_corecnt() functions.

The above is achieved through adding a new erratum: ARM64_ERRATUM_2457168.

d3916da4bc arm64: errata: Add Cortex-A510 to the repeat tlbi list
commit 39fdb65f52 upstream.

Cortex-A510 is affected by an erratum where in rare circumstances the
CPUs may not handle a race between a break-before-make sequence on one
CPU, and another CPU accessing the same page. This could allow a store
to a page that has been unmapped.

Work around this by adding the affected CPUs to the list that needs
TLB sequences to be done twice.

a8ba16e9f1 docs: kerneldoc-preamble: Test xeCJK.sty before loading
commit cee7db1b02 upstream.

On distros whose texlive packaging is fine-grained, texlive-xecjk
can be installed/removed independently of other texlive packages.
Conditionally loading xeCJK depending only on the existence of the
"Noto Sans CJK SC" font might end up in xelatex error of
"xeCJK.sty not found!".

Improve the situation by testing existence of xeCJK.sty before
loading it.

This is useful on RHEL 9 and its clone distros where texlive-xecjk
doesn't work at the moment due to a missing dependency [1].
"make pdfdocs" for non-CJK contents should work after removing
texlive-xecjk.

f83cbd14c7 arm64: fix rodata=full
commit 2e8cff0a0e upstream.

On arm64, "rodata=full" has been suppored (but not documented) since
commit:

  c55191e96c ("arm64: mm: apply r/o permissions of VM areas to its linear alias as well")

As it's necessary to determine the rodata configuration early during
boot, arm64 has an early_param() handler for this, whereas init/main.c
has a __setup() handler which is run later.

Unfortunately, this split meant that since commit:

  f9a40b0890 ("init/main.c: return 1 from handled __setup() functions")

... passing "rodata=full" would result in a spurious warning from the
__setup() handler (though RO permissions would be configured
appropriately).

Further, "rodata=full" has been broken since commit:

  0d6ea3ac94 ("lib/kstrtox.c: add "false"/"true" support to kstrtobool()")

... which caused strtobool() to parse "full" as false (in addition to
many other values not documented for the "rodata=" kernel parameter.

This patch fixes this breakage by:

* Moving the core parameter parser to an __early_param(), such that it
  is available early.

* Adding an (optional) arch hook which arm64 can use to parse "full".

* Updating the documentation to mention that "full" is valid for arm64.

* Having the core parameter parser handle "on" and "off" explicitly,
  such that any undocumented values (e.g. typos such as "ful") are
  reported as errors rather than being silently accepted.

Note that __setup() and early_param() have opposite conventions for
their return values, where __setup() uses 1 to indicate a parameter was
handled and early_param() uses 0 to indicate a parameter was handled.

Fixes: f9a40b0890 ("init/main.c: return 1 from handled __setup() functions")
Fixes: 0d6ea3ac94 ("lib/kstrtox.c: add "false"/"true" support to kstrtobool()")

c2f242d958 powerpc/pseries/mobility: set NMI watchdog factor during an LPM
[ Upstream commit 118b136693 ]

During an LPM, while the memory transfer is in progress on the arrival
side, some latencies are generated when accessing not yet transferred
pages on the arrival side. Thus, the NMI watchdog may be triggered too
frequently, which increases the risk to hit an NMI interrupt in a bad
place in the kernel, leading to a kernel panic.

Disabling the Hard Lockup Watchdog until the memory transfer could be a
too strong work around, some users would want this timeout to be
eventually triggered if the system is hanging even during an LPM.

Introduce a new sysctl variable nmi_watchdog_factor. It allows to apply
a factor to the NMI watchdog timeout during an LPM. Just before the CPUs
are stopped for the switchover sequence, the NMI watchdog timer is set
to watchdog_thresh + factor%

A value of 0 has no effect. The default value is 200, meaning that the
NMI watchdog is set to 30s during LPM (based on a 10s watchdog_thresh
value). Once the memory transfer is achieved, the factor is reset to 0.

Setting this value to a high number is like disabling the NMI watchdog
during an LPM.

cc4ac4cc41 dt-bindings: pinctrl: mt8192: Use generic bias instead of pull-*-adv
commit 353d2ef77f upstream.

Commit cafe19db77 ("pinctrl: mediatek: Backward compatible to previous
Mediatek's bias-pull usage") allowed the bias-pull-up and bias-pull-down
properties to be used for setting PUPD/R1/R0 type bias on mtk-paris
based SoC's, which was previously only supported by the custom
mediatek,pull-up-adv and mediatek,pull-down-adv properties.

Since the bias-pull-{up,down} properties already have defines associated
thus being more descriptive and is more universal on MediaTek platforms,
and given that there are no mediatek,pull-{up,down}-adv users on mt8192
yet, remove the custom adv properties in favor of the generic ones.

Note that only mediatek,pull-up-adv was merged in the binding, but not
its down counterpart.

1e60eaa884 locking/atomic: Make test_and_*_bit() ordered on failure
commit 415d832497 upstream.

These operations are documented as always ordered in
include/asm-generic/bitops/instrumented-atomic.h, and producer-consumer
type use cases where one side needs to ensure a flag is left pending
after some shared data was updated rely on this ordering, even in the
failure case.

This is the case with the workqueue code, which currently suffers from a
reproducible ordering violation on Apple M1 platforms (which are
notoriously out-of-order) that ends up causing the TTY layer to fail to
deliver data to userspace properly under the right conditions.  This
change fixes that bug.

Change the documentation to restrict the "no order on failure" story to
the _lock() variant (for which it makes sense), and remove the
early-exit from the generic implementation, which is what causes the
missing barrier semantics in that case.  Without this, the remaining
atomic op is fully ordered (including on ARM64 LSE, as of recent
versions of the architecture spec).

8acd0e8d03 xen-blkfront: Apply 'feature_persistent' parameter when connect
commit 402c43ea6b upstream.

In some use cases[1], the backend is created while the frontend doesn't
support the persistent grants feature, but later the frontend can be
changed to support the feature and reconnect.  In the past, 'blkback'
enabled the persistent grants feature since it unconditionally checked
if frontend supports the persistent grants feature for every connect
('connect_ring()') and decided whether it should use persistent grans or
not.

However, commit aac8a70db2 ("xen-blkback: add a parameter for
disabling of persistent grants") has mistakenly changed the behavior.
It made the frontend feature support check to not be repeated once it
shown the 'feature_persistent' as 'false', or the frontend doesn't
support persistent grants.

Similar behavioral change has made on 'blkfront' by commit 74a852479c
("xen-blkfront: add a parameter for disabling of persistent grants").
This commit changes the behavior of the parameter to make effect for
every connect, so that the previous behavior of 'blkfront' can be
restored.

AMD's "Technical Guidance for Mitigating Branch Type Confusion,
Rev. 1.0 2022-07-12" whitepaper, under section 6.1.2 "IBPB On
Privileged Mode Entry / SMT Safety" says:

  Similar to the Jmp2Ret mitigation, if the code on the sibling thread
  cannot be trusted, software should set STIBP to 1 or disable SMT to
  ensure SMT safety when using this mitigation.

So, like already being done for retbleed=unret, and now also for
retbleed=ibpb, force STIBP on machines that have it, and report its SMT
vulnerability status accordingly.

[ Upstream commit c4a179c716 ]

The HEVC specification describes the following:
"PicOrderCntVal is derived as follows:
PicOrderCntVal = PicOrderCntMsb + slice_pic_order_cnt_lsb
The value of PicOrderCntVal shall be in the range of
−2^31 to 2^31 − 1, inclusive."

To match with these definitions change __u16 pic_order_cnt[2]
into __s32 pic_order_cnt_val.
Change v4l2_ctrl_hevc_slice_params->slice_pic_order_cnt to __s32 too.

8cd41a4f28 dm writecache: count number of blocks discarded, not number of discard bios
[ Upstream commit 2ee73ef60d ]

Change dm-writecache, so that it counts the number of blocks discarded
instead of the number of discard bios. Make it consistent with the
read and write statistics counters that were changed to count the
number of blocks instead of bios.

[ Upstream commit b2676e1482 ]

Change dm-writecache, so that it counts the number of blocks written
instead of the number of write bios. Bios can be split and requeued
using the dm_accept_partial_bio function, so counting bios caused
inaccurate results.

019aa3dd4e arm64: errata: Remove AES hwcap for COMPAT tasks
[ Upstream commit 44b3834b2e ]

Cortex-A57 and Cortex-A72 have an erratum where an interrupt that
occurs between a pair of AES instructions in aarch32 mode may corrupt
the ELR. The task will subsequently produce the wrong AES result.

The AES instructions are part of the cryptographic extensions, which are
optional. User-space software will detect the support for these
instructions from the hwcaps. If the platform doesn't support these
instructions a software implementation should be used.

Remove the hwcap bits on affected parts to indicate user-space should
not use the AES instructions.
