The cgrp_ancestor_storage has two drawbacks:
- it's not guaranteed that the member immediately follows struct cgrp in
cgroup_root (root cgroup's ancestors[0] might thus point to a padding
and not in cgrp_ancestor_storage proper),
- this idiom raises warnings with -Wflex-array-member-not-at-end.
Instead of relying on the auxiliary member in cgroup_root, define the
0-th level ancestor inside struct cgroup (needed for static allocation
of cgrp_dfl_root), deeper cgroups would allocate flexible
_low_ancestors[]. Unionized alias through ancestors[] will
transparently join the two ranges.
The above change would still leave the flexible array at the end of
struct cgroup inside cgroup_root, so move cgrp also towards the end of
cgroup_root to resolve the -Wflex-array-member-not-at-end.

A bug was reported about an infinite recursion caused by tracing the rcu
events with the kernel stack trace trigger enabled. The stack trace code
called back into RCU which then called the stack trace again.
Expand the ftrace recursion protection to add a set of bits to protect
events from recursion. Each bit represents the context that the event is
in (normal, softirq, interrupt and NMI).
Have the stack trace code use the interrupt context to protect against
recursion.
Note, the bug showed an issue in both the RCU code as well as the tracing
stacktrace code. This only handles the tracing stack trace side of the
bug. The RCU fix will be handled separately.

The code has integrity checks to make sure that depth never goes below
zero. But the depth field has recently been converted to unsigned long
from "int" (for alignment reasons). As unsigned long can never be less
than zero, the integrity checks no longer work.
Convert depth to long from unsigned long to allow the integrity checks to
work again.

Qualcomm GX(graphics) is a clock controller which has PLLs, clocks and
Power domains (GDSC), but the requirement from the SW driver is to use
the GDSC power domain from the clock controller to recover the GPU
firmware in case of any failure/hangs. The rest of the resources of the
clock controller are being used by the firmware of GPU. This module
exposes the GDSC power domains which helps the recovery of Graphics
subsystem.
Add bindings documentation for the Kaanapali Graphics Clock and Graphics
power domain Controller for Kaanapali SoC.

bio_may_need_split() uses bi_vcnt to determine if a bio has a single
segment, but bi_vcnt is unreliable for cloned bios. Cloned bios share
the parent's bi_io_vec array but iterate over a subset via bi_iter,
so bi_vcnt may not reflect the actual segment count being iterated.
Replace the bi_vcnt check with bvec iterator access via
__bvec_iter_bvec(), comparing bi_iter.bi_size against the current
bvec's length. This correctly handles both cloned and non-cloned bios.
Move bi_io_vec into the first cache line adjacent to bi_iter. This is
a sensible layout since bi_io_vec and bi_iter are commonly accessed
together throughout the block layer - every bvec iteration requires
both fields. This displaces bi_end_io to the second cache line, which
is acceptable since bi_end_io and bi_private are always fetched
together in bio_endio() anyway.
The struct layout change requires bio_reset() to preserve and restore
bi_io_vec across the memset, since it now falls within BIO_RESET_BYTES.
Nitesh verified that this patch doesn't regress NVMe 512-byte IO perf [1].

context, including:
- thread information
- CPU/IO priority
- lock information
- elapsed time
- total time
- running time (depend on CONFIG_64BIT)
- runnable time (depend on CONFIG_SCHED_INFO and CONFIG_SCHEDSTATS)
- io sleep time (depend on CONFIG_TASK_DELAY_ACCT and

Use DEFINE_RAW_FLEX() to avoid thousands of -Wflex-array-member-not-at-end
warnings.
Remove struct ip_options_data, and adjust the rest of the code so that
flexible-array member struct ip_options_rcu::opt.__data[] ends last
in struct icmp_bxm.
Compensate for this by using the DEFINE_RAW_FLEX() helper to define each
on-stack struct instance that contained struct ip_options_data as a member,
and to define struct ip_options_rcu with a fixed on-stack size for its
nested flexible-array member opt.__data[].
Also, add a couple of code comments to prevent people from adding members
to a struct after another member that contains a flexible array.

Move the struct phys_vec definition from block/blk-mq-dma.c to
include/linux/types.h to make it available for use across the kernel.
The phys_vec structure represents a physical address range with a
length, which is used by the new physical address-based DMA mapping
API. This structure is already used by the block layer and will be
needed for DMA phys API users.
Moving this definition to types.h provides a centralized location
for this common data structure and eliminates code duplication
across subsystems that need to work with physical address ranges.

Remove SYSCTL_INT_CONV_CUSTOM and replace it with proc_int_conv. This
converter function expects a negp argument as it can take on negative
values. Update all jiffies converters to use explicit function calls.
Remove SYSCTL_CONV_IDENTITY as it is no longer used.

Replace SYSCTL_USER_TO_KERN_INT_CONV and SYSCTL_KERN_TO_USER_INT_CONV
macros with function implementing the same logic.This makes debugging
easier and aligns with the functions preference described in
coding-style.rst. Update all jiffies converters to use explicit function
implementations instead of macro-generated versions.

The Mali C55 driver uses the v4l2-isp framework, which defines its own
versioning number which does not need to be defined again in each
platform-specific header.
Remove the definition of mali_c55_param_buffer_version enumeration from
the Mali C55 uAPI header.
