Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull more kvm updates from Paolo Bonzini:
"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"
