[GIT PULL] KVM/arm64 fixes for 7.1, take #1

[Marc Zyngier <maz@kernel.org>]

Paolo,

This is the first drop of KVM/arm64 fixes for 7.1. Nothing really
major so far, but a rather wide range of fixes for idreg handling,
long standing regressions, SMCCC compliance and more. Add a few
cleanups to the fix, and that's about it. As usual, gory details in
the tag below.

Please pull,

	M.

  KVM: arm64: Wake-up from WFI when iqrchip is in userspace (2026-04-24 12:03:57 +0100)

----------------------------------------------------------------
KVM/arm64 fixes for 7.1, take #1

- Allow tracing for non-pKVM, which was accidentally disabled when
  the series was merged

- Rationalise the way the pKVM hypercall ranges are defined by using
  the same mechanism as already used for the vcpu_sysreg enum

- Enforce that SMCCC function numbers relayed by the pKVM proxy are
  actually compliant with the specification

- Fix a couple of feature to idreg mappings which resulted in the
  wrong sanitisation being applied

- Fix the GICD_IIDR revision number field that could never been
  written correctly by userspace

- Make kvm_vcpu_initialized() correctly use its parameter instead
  of relying on the surrounding context

- Enforce correct ordering in __pkvm_init_vcpu(), plugging a
  potential pin leak at the same time

- Move __pkvm_init_finalise() to a less dangerous spot, avoiding
  future problems

- Restore functional userspace irqchip support after a four year
  breakage (last functional kernel was 5.18...). This is obviously
  ripe for garbage collection.

- ... and the usual lot of spelling fixes
