Pull kvm fixes from Paolo Bonzini: "Tools: - kvm_stat: do not show halt_wait_ns since it is not a cumulative statistic x86: - clean ups and fixes for bus lock vmexit and lazy allocation of rmaps - two fixes for SEV-ES (one more coming as soon as I get reviews) - fix for static_key underflow ARM: - Properly refcount pages used as a concatenated stage-2 PGD - Fix missing unlock when detecting the use of MTE+VM_SHARED" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: SEV-ES: reduce ghcb_sa_len to 32 bits KVM: VMX: Remove redundant handling of bus lock vmexit KVM: kvm_stat: do not show halt_wait_ns KVM: x86: WARN if APIC HW/SW disable static keys are non-zero on unload Revert "KVM: x86: Open code necessary bits of kvm_lapic_set_base() at vCPU RESET" KVM: SEV-ES: Set guest_state_protected after VMSA update KVM: X86: fix lazy allocation of rmaps KVM: SEV-ES: fix length of string I/O KVM: arm64: Release mmap_lock when using VM_SHARED with MTE KVM: arm64: Report corrupted refcount at EL2 KVM: arm64: Fix host stage-2 PGD refcount KVM: s390: Function documentation fixes
