Linus Torvalds c89d780cc1 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

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:
 "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.

  Core:

   - 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

   - 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

  ACPI:

   - 'acpi=nospcr' option to disable SPCR as default console for arm64

   - Move some ACPI code (cpuidle, FFH) to drivers/acpi/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

  Kselftest updates:

   - Kernel mode NEON fp-stress

   - Cleanups, spelling mistakes

  Miscellaneous:

   - arm64 Documentation update with a minor clarification on TBI

   - 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"
