[GIT PULL] KVM/arm64 fixes for 6.11, round #1

[Oliver Upton <oliver.upton@linux.dev>]

Hi Paolo,

Decent bit of fixes this time around. The most noteworthy among these
is probably Marc's vgic fix that closes a race which can precipitate a
UAF, as seen w/ syskaller.

Please pull.

  KVM: arm64: vgic: Hold config_lock while tearing down a CPU interface (2024-08-08 16:58:22 +0000)

----------------------------------------------------------------
KVM/arm64 fixes for 6.11, round #1

 - Use kvfree() for the kvmalloc'd nested MMUs array

 - Set of fixes to address warnings in W=1 builds

 - Make KVM depend on assembler support for ARMv8.4

 - Fix for vgic-debug interface for VMs without LPIs

 - Actually check ID_AA64MMFR3_EL1.S1PIE in get-reg-list selftest

 - Minor code / comment cleanups for configuring PAuth traps

 - Take kvm->arch.config_lock to prevent destruction / initialization
   race for a vCPU's CPUIF which may lead to a UAF
