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.

Thanks,

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
