fwnode_for_each_child_node() bumps a reference counting of a returned variable.
We have to balance it whenever we return to the caller.
OTOH, the successful iteration will drop reference count under the hood, no need
to do it twice.

warns about it:

- Prevent PSI state corruption when schedule() races with cgroup move. A
recent commit combined two PSI callbacks to reduce the number of cgroup
tree updates, but missed that schedule() can drop rq::lock for load
balancing, which opens the race window for cgroup_move_task() which then
observes half updated state. The fix is to solely use task::ps_flags
instead of looking at the potentially mismatching scheduler state
- Prevent an out-of-bounds access in uclamp caused bu a rounding division
which can lead to an off-by-one error exceeding the buckets array size.
- Prevent unfairness caused by missing load decay when a task is attached
to a cfs runqueue. The old load of the task is attached to the runqueue
and never removed. Fix it by enforcing the load update through the
hierarchy for unthrottled run queue instances.
- A documentation fix fot the 'sched_verbose' command line option

Pull scheduler fixes from Thomas Gleixner:
"A set of scheduler updates:
- Prevent PSI state corruption when schedule() races with cgroup
move.
A recent commit combined two PSI callbacks to reduce the number of
cgroup tree updates, but missed that schedule() can drop rq::lock
for load balancing, which opens the race window for
cgroup_move_task() which then observes half updated state.
The fix is to solely use task::ps_flags instead of looking at the
potentially mismatching scheduler state
- Prevent an out-of-bounds access in uclamp caused bu a rounding
division which can lead to an off-by-one error exceeding the
buckets array size.
- Prevent unfairness caused by missing load decay when a task is
attached to a cfs runqueue.
The old load of the task was attached to the runqueue and never
removed. Fix it by enforcing the load update through the hierarchy
for unthrottled run queue instances.
- A documentation fix fot the 'sched_verbose' command line option"

- Two fixes for the futex syscall related to the timeout handling.
FUTEX_LOCK_PI does not support the FUTEX_CLOCK_REALTIME bit and because
it's not set the time namespace adjustment for clock MONOTONIC is
applied wrongly.
FUTEX_WAIT cannot support the FUTEX_CLOCK_REALTIME bit because its
always a relative timeout.
- Cleanups in the futex syscall entry points which became obvious when
the two timeout handling bugs were fixed.
- Cleanup of queued_write_lock_slowpath() as suggested by Linus
- Fixup of the smp_call_function_single_async() prototype

intel_dp_check_mst_status() uses a 14-byte array to read the DPRX Event
Status Indicator data, but then passes that buffer at offset 10 off as
an argument to drm_dp_channel_eq_ok().
End result: there are only 4 bytes remaining of the buffer, yet
drm_dp_channel_eq_ok() wants a 6-byte buffer. gcc-11 correctly warns
about this case:

This commit just extends the original array by 2 zero-initialized bytes,
avoiding the warning.
There may be some underlying bug in here that caused this confusion, but
this is at least no worse than the existing situation that could use

Mounting with "multichannel" is obviously implied if user requested
more than one channel on mount (ie mount parm max_channels>1).
Currently both have to be specified. Fix that so that if max_channels
is greater than 1 on mount, enable multichannel rather than silently
falling back to non-multichannel.

Pull powerpc updates and fixes from Michael Ellerman:
"A bit of a mixture of things, tying up some loose ends.
There's the removal of the nvlink code, which dependend on a commit in
the vfio tree. Then the enablement of huge vmalloc which was in next
for a few weeks but got dropped due to conflicts. And there's also a
few fixes.
Summary:
- Remove the nvlink support now that it's only user has been removed.
- Enable huge vmalloc mappings for Radix MMU (P9).
- Fix KVM conversion to gfn-based MMU notifier callbacks.
- Fix a kexec/kdump crash with hot plugged CPUs.
- Fix boot failure on 32-bit with CONFIG_STACKPROTECTOR.
- Restore alphabetic order of the selects under CONFIG_PPC.
Thanks to: Christophe Leroy, Christoph Hellwig, Nicholas Piggin,
Sandipan Das, and Sourabh Jain"

In the SMB3/SMB3.1.1 negotiate protocol request, we are supposed to
advertise CAP_MULTICHANNEL capability when establishing multiple
channels has been requested by the user doing the mount. See MS-SMB2
sections 2.2.3 and 3.2.5.2
Without setting it there is some risk that multichannel could fail
if the server interpreted the field strictly.

<linux/kconfig.h> is included from all the kernel-space source files,
including C, assembly, linker scripts. It is intended to contain a
minimal set of macros to evaluate CONFIG options.
IF_ENABLED() is an intruder here because (x ? y : z) is C code, which
should not be included from assembly files or linker scripts.
Also, <linux/kconfig.h> is no longer self-contained because NULL is
defined in <linux/stddef.h>.
Move IF_ENABLED() out to <linux/kernel.h> as PTR_IF(). PTF_IF()
takes the general boolean expression instead of a CONFIG option
so that it fits better in <linux/kernel.h>.

Merge master back into next, this allows us to resolve some conflicts in
arch/powerpc/Kconfig, and also re-sort the symbols under config PPC so
that they are in alphabetical order again.
