Subject: [GIT PULL] arm64 updates for 6.11
Hi Linus,
I'm about to go on holiday for two weeks, so here's an early pull
request for 6.11. The biggest part is the virtual CPU hotplug that
touches ACPI, irqchip. We also have some GICv3 optimisation for
pseudo-NMIs that has been queued via the arm64 tree. Otherwise the usual
perf updates, kselftest, various small cleanups. There's a minor
conflict currently in -next with the kvmarm tree but it's trivial (in
arch/arm64/include/asm/esr.h).
I'll check emails occasionally during the merging window but if there's
anything urgent, Will can take over.
Thanks.

Merge branch 'for-next/vcpu-hotplug' into for-next/core (2024-07-11 19:10:02 +0100)
----------------------------------------------------------------
arm64 updates for 6.11:
* Virtual CPU hotplug support for arm64 ACPI systems
* cpufeature infrastructure cleanups and making the FEAT_ECBHB ID bits
visible to guests
* CPU errata: expand the speculative SSBS workaround to more CPUs
* arm64 ACPI:
- acpi=nospcr option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
* GICv3, use compile-time PMR values: optimise the way regular IRQs are
masked/unmasked when GICv3 pseudo-NMIs are used, removing the need for
a static key in fast paths by using a priority value chosen
dynamically at boot time
* arm64 perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4
- Add missing PMU driver MODULE_DESCRIPTION() strings
- Hook up DT compatibles for recent CPU PMUs
* arm64 kselftest updates:
- Kernel mode NEON fp-stress
- Cleanups, spelling mistakes
* arm64 Documentation update with a minor clarification on TBI
* Miscellaneous:
- Fix missing IPI statistics
- Implement raw_smp_processor_id() using thread_info rather than a
per-CPU variable (better code generation)
- Make MTE checking of in-kernel asynchronous tag faults conditional
on KASAN being enabled
- Minor cleanups, typos
