Qualcomm driver updates for v6.15
Improve the client interface for the Qualcomm ICE driver to avoid
leaking references, including fixing the client drivers to call the new
function.
Adopt str_on_off() helper in AOSS driver and mark non-global servreg QMI
element info array in the PDR driver static.

* kvm-arm64/pv-cpuid:
: Paravirtualized implementation ID, courtesy of Shameer Kolothum
:
: Big-little has historically been a pain in the ass to virtualize. The
: implementation ID (MIDR, REVIDR, AIDR) of a vCPU can change at the whim
: of vCPU scheduling. This can be particularly annoying when the guest
: needs to know the underlying implementation to mitigate errata.
:
: "Hyperscalers" face a similar scheduling problem, where VMs may freely
: migrate between hosts in a pool of heterogenous hardware. And yes, our
: server-class friends are equally riddled with errata too.
:
: In absence of an architected solution to this wart on the ecosystem,
: introduce support for paravirtualizing the implementation exposed
: to a VM, allowing the VMM to describe the pool of implementations that a
: VM may be exposed to due to scheduling/migration.
:
: Userspace is expected to intercept and handle these hypercalls using the
: SMCCC filter UAPI, should it choose to do so.

For more than a decade, CONFIG_SCHED_DEBUG=y has been enabled
in all the major Linux distributions:
/boot/config-6.11.0-19-generic:CONFIG_SCHED_DEBUG=y
The reason is that while originally CONFIG_SCHED_DEBUG started
out as a debugging feature, over the years (decades ...) it has
grown various bits of statistics, instrumentation and
control knobs that are useful for sysadmin and general software
development purposes as well.
But within the kernel we still pretend that there's a choice,
and sometimes code that is seemingly 'debug only' creates overhead
that should be optimized in reality.
So make it all official and make CONFIG_SCHED_DEBUG unconditional.
Now that all uses of CONFIG_SCHED_DEBUG are removed from
the code by previous patches, remove the Kconfig option as well.

All the big Linux distros enable CONFIG_SCHED_DEBUG, because
the various features it provides help not just with kernel
development, but with system administration and user-space
software development as well.
Reflect this reality and enable this functionality
unconditionally.

The scheduler has this special SCHED_WARN() facility that
depends on CONFIG_SCHED_DEBUG.
Since CONFIG_SCHED_DEBUG is getting removed, convert
SCHED_WARN() to WARN_ON_ONCE().
Note that the warning output isn't 100% equivalent:
#define SCHED_WARN_ON(x) WARN_ONCE(x, #x)
Because SCHED_WARN_ON() would output the 'x' condition
as well, while WARN_ONCE() will only show a backtrace.
Hopefully these are rare enough to not really matter.
If it does, we should probably introduce a new WARN_ON()
variant that outputs the condition in stringified form,
or improve WARN_ON() itself.

Track whether pages were unmapped from any MM (even ones with a currently
empty mm_cpumask) by the reclaim code, to figure out whether or not
broadcast TLB flush should be done when reclaim finishes.
The reason any MM must be tracked, and not only ones contributing to the
tlbbatch cpumask, is that broadcast ASIDs are expected to be kept up to
date even on CPUs where the MM is not currently active.
This change allows reclaim to avoid doing TLB flushes when only clean page
cache pages and/or slab memory were reclaimed, which is fairly common.
( This is a simpler alternative to the code that was in my INVLPGB series
before, and it seems to capture most of the benefit due to how common
it is to reclaim only page cache. )

Architectural Perfmon was introduced on the Family 6 "Core" processors
starting with Yonah. Processors before Yonah need their own customized
PMU initialization.
p6_pmu_init() is expected to provide that initialization for early
Family 6 processors. But, currently, it could get called for any Family
6 processor if the architectural perfmon feature is disabled on that
processor. To simplify, restrict the P6 PMU initialization to early
Family 6 processors that do not have architectural perfmon support and
truly need the special handling.
As a result, the "unsupported" console print becomes practically
unreachable because all the released P6 processors are covered by the
switch cases. Move the console print to a common location where it can
cover all modern processors (including Family >15) that may not have
architectural perfmon support enumerated.
Also, use this opportunity to get rid of the unnecessary switch cases in
P6 initialization. Only the Pentium Pro processor needs a quirk, and the
rest of the processors do not need any special handling. The gaps in the
case numbers are only due to no processor with those model numbers being
released.
Use decimal numbers to represent Intel Family numbers. Also, convert one
of the last few Intel x86_model comparisons to a VFM-based one.

Intel made a late change to the AVX10 specification that removes support
for a 256-bit maximum vector length and enumeration of the maximum
vector length. AVX10 will imply a maximum vector length of 512 bits.
I.e. there won't be any such thing as AVX10/256 or AVX10/512; there will
just be AVX10, and it will essentially just consolidate AVX512 features.
As a result of this new development, my strategy of providing both
*_avx10_256 and *_avx10_512 functions didn't turn out to be that useful.
The only remaining motivation for the 256-bit AVX512 / AVX10 functions
is to avoid downclocking on older Intel CPUs. But I already wrote
*_avx2 code too (primarily to support CPUs without AVX512), which
performs almost as well as *_avx10_256. So we should just use that.
Therefore, remove the *_avx10_256 CRC functions, and rename the
*_avx10_512 CRC functions to *_avx512. Make Ice Lake and Tiger Lake use
the *_avx2 functions instead of *_avx10_256 which they previously used.
