Pull cgroup fixes from Tejun Heo:
 "During the v6.2 cycle, there were a series of changes to task cpu
  affinity handling which fixed cpuset inadvertently clobbering
  user-configured affinity masks. Unfortunately, they broke the affinity
  handling on hybrid heterogeneous CPUs which have cores that can
  execute both 64 and 32bit along with cores that can only execute 32bit
  code.

  This contains two fix patches for the above issue. While reverting the
  changes that caused the regression is definitely an option, the
  origial patches do improve how cpuset behave signficantly in some
  cases and the fixes seem fairly safe, so I think it'd be better to try
  to fix them first"

set_cpus_allowed_ptr() will fail with -EINVAL if the requested
affinity mask is not a subset of the task_cpu_possible_mask() for the
task being updated. Consequently, on a heterogeneous system with cpusets
spanning the different CPU types, updates to the cgroup hierarchy can
silently fail to update task affinities when the effective affinity
mask for the cpuset is expanded.

For example, consider an arm64 system with 4 CPUs, where CPUs 2-3 are
the only cores capable of executing 32-bit tasks. Attaching a 32-bit
task to a cpuset containing CPUs 0-2 will correctly affine the task to
CPU 2. Extending the cpuset to CPUs 0-3, however, will fail to extend
the affinity mask of the 32-bit task because update_tasks_cpumask() will
pass the full 0-3 mask to set_cpus_allowed_ptr().

Extend update_tasks_cpumask() to take a temporary 'cpumask' paramater
and use it to mask the 'effective_cpus' mask with the possible mask for
each task being updated.

Since commit 8f9ea86f ("sched: Always preserve the user
requested cpumask"), relax_compatible_cpus_allowed_ptr() is calling
__sched_setaffinity() unconditionally. This helps to expose a bug in
the current cpuset hotplug code where the cpumasks of the tasks in
the top cpuset are not updated at all when some CPUs become online or
offline. It is likely caused by the fact that some of the tasks in the
top cpuset, like percpu kthreads, cannot have their cpu affinity changed.

One way to reproduce this as suggested by Peter is:
 - boot machine
 - offline all CPUs except one
 - taskset -p ffffffff $$
 - online all CPUs

Fix this by allowing cpuset_cpus_allowed() to return a wider mask that
includes offline CPUs for those tasks that are in the top cpuset. For
tasks not in the top cpuset, the old rule applies and only online CPUs
will be returned in the mask since hotplug events will update their
cpumasks accordingly.

It was reported that commit b300667b ("HID: amd_sfh: Disable the
interrupt for all command") had caused increased resume time on HP Envy
x360.

Before this commit 3 sensors were reported, but they were not actually
functional.  After this commit the sensors are no longer reported, but
also the resume time increased.

To avoid this problem explicitly look for the number of disabled sensors.
If all the sensors are disabled, clean everything up.

On some Logitech mice, such as the G903, and possibly the G403, the HID
events are generated on a different interface to the HID++ one.

If we enable hi-res through the HID++ interface, the HID interface
wouldn't know anything about it, and handle the events as if they were
regular scroll events, making the mouse unusable.

Disable hi-res scrolling on those devices until we implement scroll
events through HID++.

 "A bit bigger than I'd like at this point, but mostly a bunch of little
  fixes. In detail:

   - NVMe pull request via Christoph:
       - Fix a missing queue put in nvmet_fc_ls_create_association
         (Amit Engel)

Pull ceph fix from Ilya Dryomov:
 "A safeguard to prevent the kernel client from further damaging the
  filesystem after running into a case of an invalid snap trace.

  The root cause of this metadata corruption is still being investigated
  but it appears to be stemming from the MDS. As such, this is the best
  we can do for now"

 - handle potential mremap() failure gracefully

 - don't reject EFI memory attributes table version 2

Pull RISC-V fixes from Palmer Dabbelt:

 - A build fix to avoid static branches in cpu_relax(), which greatly
   inflates the jump tables and breaks at least
   CONFIG_CC_OPTIMIZE_FOR_SIZE=y.

 - A fix for a kernel panic when probing impossible instruction
   positions.

 - A fix to disable unwind tables, which are enabled by default for
   GCC-13 and result in unhandled relocations in modules.

When iterating on a linked list, a result of memremap is dereferenced
without checking it for NULL.

This patch adds a check that falls back on allocating a new page in
case memremap doesn't succeed.

[ardb: return -ENOMEM instead of breaking out of the loop]
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time.  To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic
at once.
