Use the newer RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros
instead of SET_RUNTIME_PM_OPS() and SET_SYSTEM_SLEEP_PM_OPS() together
with pm_ptr(), which allows us dropping ugly __maybe_unused
attributes.
This optimizes slightly when CONFIG_PM is disabled, too.

Currently, scmi_pd_power() explicitly verifies whether the requested
power state was applied by calling state_get(). While this check could
detect failures where the state was not properly updated, ensuring
correctness is the responsibility of the SCMI firmware.
Removing this redundant state_get() call eliminates an unnecessary
round-trip to the firmware, improving efficiency. Any mismatches
between the requested and actual states should be handled by the SCMI
firmware, which must return a failure if state_set() is unsuccessful.
Additionally, in some cases, checking the state after powering off a
domain may be unreliable or unsafe, depending on the firmware
implementation.
This patch removes the redundant verification, simplifying the function
without compromising correctness.

Since the firmware code can easily be enabled for compile testing, there
is no need to add stubs either, so just make it a hard dependency.

Initially in commit 6891c4509c79 memset() was required to clear a variable
allocated on stack. Commit 2482097c6c0f removed the on stack variable and
retained the memset() despite the fact that the memory is allocated via
kmem_cache_zalloc() and therefore zereoed already.
Drop the redundant memset().

it seems that if user sets pollfd with POLLRDNORM in userspace, perf_poll

Pinned performance events can enter an error state when they fail to be
scheduled in the context due to a failed constraint or some other conflict
or condition.
In error state these events won't generate any samples anymore and are
silently ignored until they are recovered by PERF_EVENT_IOC_ENABLE,
or the condition can also change so that they can be scheduled in.
Tooling should be allowed to know about the state change, but
currently there's no mechanism to notify tooling when events enter
an error state.
One way to do this is to issue a POLLHUP event to poll(2) to handle this.
Reading events in an error state would return 0 (EOF) and it matches to
the behavior of POLLHUP according to the man page.
Tooling should remove the fd of the event from pollfd after getting
POLLHUP, otherwise it'll be returned repeatedly.

In the past year, I've primarily focused on shmem and added several
features to it, such as support for mTHP, large folio swap-out and swap-in
support, mTHP collapse support, skipping swapcache, and tmpfs support for
large folios, and so on. Meanwhile I've also been helping with testing
and reviewing shmem related patches.
So I am willing to continue assisting with testing and reviewing shmem
related patches. Let me be Cc'd on patches related to shmem.

Similar to commit 255ff62d1586 ("docs: tmpfs: drop 'fadvise()' from the
documentation"), fadvise() has no HUGEPAGE advise currently. Remove the
confusing fadvise() comments.

zpool_malloc_support_movable() always returns true for zsmalloc, the only
remaining zpool driver. Remove it and set the gfp flags in
zswap_compress() accordingly. Opportunistically use GFP_NOWAIT instead of
__GFP_NOWARN | __GFP_KSWAPD_RECLAIM for conciseness as they are
equivalent.

zs_map_object() and zs_unmap_object() are no longer used, remove them.
Since these are the only users of per-CPU mapping_areas, remove them and
the associated CPU hotplug callbacks too.
