Merge tag 'kvmarm-fixes-5.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into kvm-master (2021-11-12 16:01:55 -0500)
----------------------------------------------------------------
New x86 features:
* Guest API and guest kernel support for SEV live migration
* SEV and SEV-ES intra-host migration
Bugfixes and cleanups for x86:
* Fix misuse of gfn-to-pfn cache when recording guest steal time / preempted status
* Fix selftests on APICv machines
* Fix sparse warnings
* Fix detection of KVM features in CPUID
* Cleanups for bogus writes to MSR_KVM_PV_EOI_EN
* Fixes and cleanups for MSR bitmap handling
* Cleanups for INVPCID
* Make x86 KVM_SOFT_MAX_VCPUS consistent with other architectures
Bugfixes for ARM:
* Fix finalization of host stage2 mappings
* Tighten the return value of kvm_vcpu_preferred_target()
* Make sure the extraction of ESR_ELx.EC is limited to architected bits
