Adding bindings to represent a virtual cpufreq device.
Virtual machines may expose MMIO regions for a virtual cpufreq device
for guests to read performance information or to request performance
selection. The virtual cpufreq device has an individual controller for
each performance domain. Performance points for a given domain can be
normalized across all domains for ease of allowing for virtual machines
to migrate between hosts.

Pedro Falcato's optimization [1] for checking sealed VMAs, which replaces
the can_modify_mm() function with an in-loop check, necessitates an update
to the mseal.rst documentation to reflect this change.
Furthermore, the document has received offline comments regarding the code
sample and suggestions for sentence clarification to enhance reader
comprehension.

The use of struct range in the CXL subsystem is growing. In particular,
the addition of Dynamic Capacity devices uses struct range in a number
of places which are reported in debug and error messages.
To wit requiring the printing of the start/end fields in each print
became cumbersome. Dan Williams mentions in [1] that it might be time
to have a print specifier for struct range similar to struct resource.
A few alternatives were considered including '%par', '%r', and '%pn'.
%pra follows that struct range is similar to struct resource (%p[rR])
but needs to be different. Based on discussions with Petr and Andy
'%pra' was chosen.[2]
Andy also suggested to keep the range prints similar to struct resource
though combined code. Add hex_range() to handle printing for both
pointer types.
Finally introduce DEFINE_RANGE() as a parallel to DEFINE_RES_*() and use
it in the tests.

PCI Express Interface PMU includes various performance counters
to monitor the data that is transmitted over the PCIe link. The
counters track various inbound and outbound transactions which
includes separate counters for posted/non-posted/completion TLPs.
Also, inbound and outbound memory read requests along with their
latencies can also be monitored. Address Translation Services(ATS)events
such as ATS Translation, ATS Page Request, ATS Invalidation along with
their corresponding latencies are also supported.
The performance counters are 64 bits wide.
For instance,
perf stat -e ib_tlp_pr <workload>
tracks the inbound posted TLPs for the workload.

Most of the callers of wbc_account_cgroup_owner() are converting a folio
to page before calling the function. wbc_account_cgroup_owner() is
converting the page back to a folio to call mem_cgroup_css_from_folio().
Convert wbc_account_cgroup_owner() to take a folio instead of a page,
and convert all callers to pass a folio directly except f2fs.
Convert the page to folio for all the callers from f2fs as they were the
only callers calling wbc_account_cgroup_owner() with a page. As f2fs is
already in the process of converting to folios, these call sites might
also soon be calling wbc_account_cgroup_owner() with a folio directly in
the future.
No functional changes. Only compile tested.

Merge tag 'sound-6.12-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"The majority of changes here are about ASoC.
There are two core changes in ASoC (the bump of minimal topology ABI
version and the fix for references of components in DAPM code), and
others are mostly various device-specific fixes for SoundWire, AMD,
Intel, SOF, Qualcomm and FSL, in addition to a few usual HD-audio
quirks and fixes"

Drop @atomic from the myriad "to_pfn" APIs now that all callers pass
"false", and remove a comment blurb about KVM running only the "GUP fast"
part in atomic context.
No functional change intended.

Now that KVM doesn't clobber Accessed bits of shadow-present SPTEs,
e.g. when prefetching, mark folios as accessed only when zapping leaf
SPTEs, which is a rough heuristic for "only in response to an mmu_notifier
invalidation". Page aging and LRUs are tolerant of false negatives, i.e.
KVM doesn't need to be precise for correctness, and re-marking folios as
accessed when zapping entire roots or when zapping collapsible SPTEs is
expensive and adds very little value.
E.g. when a VM is dying, all of its memory is being freed; marking folios
accessed at that time provides no known value. Similarly, because KVM
marks folios as accessed when creating SPTEs, marking all folios as
accessed when userspace happens to delete a memslot doesn't add value.
The folio was marked access when the old SPTE was created, and will be
marked accessed yet again if a vCPU accesses the pfn again after reloading
a new root. Zapping collapsible SPTEs is a similar story; marking folios
accessed just because userspace disable dirty logging is a side effect of
KVM behavior, not a deliberate goal.
As an intermediate step, a.k.a. bisection point, towards *never* marking
folios accessed when dropping SPTEs, mark folios accessed when the primary
MMU might be invalidating mappings, as such zappings are not KVM initiated,
i.e. might actually be related to page aging and LRU activity.
Note, x86 is the only KVM architecture that "double dips"; every other
arch marks pfns as accessed only when mapping into the guest, not when
mapping into the guest _and_ when removing from the guest.
