Pull kvm fixes from Paolo Bonzini: "x86: - Fixes for the new scalable MMU - Fixes for migration of nested hypervisors on AMD - Fix for clang integrated assembler - Fix for left shift by 64 (UBSAN) - Small cleanups - Straggler SEV-ES patch ARM: - VM init cleanups - PSCI relay cleanups - Kill CONFIG_KVM_ARM_PMU - Fixup __init annotations - Fixup reg_to_encoding() - Fix spurious PMCR_EL0 access Misc: - selftests cleanups" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (38 commits) KVM: x86: __kvm_vcpu_halt can be static KVM: SVM: Add support for booting APs in an SEV-ES guest KVM: nSVM: cancel KVM_REQ_GET_NESTED_STATE_PAGES on nested vmexit KVM: nSVM: mark vmcb as dirty when forcingly leaving the guest mode KVM: nSVM: correctly restore nested_run_pending on migration KVM: x86/mmu: Clarify TDP MMU page list invariants KVM: x86/mmu: Ensure TDP MMU roots are freed after yield kvm: check tlbs_dirty directly KVM: x86: change in pv_eoi_get_pending() to make code more readable MAINTAINERS: Really update email address for Sean Christopherson KVM: x86: fix shift out of bounds reported by UBSAN KVM: selftests: Implement perf_test_util more conventionally KVM: selftests: Use vm_create_with_vcpus in create_vm KVM: selftests: Factor out guest mode code KVM/SVM: Remove leftover __svm_vcpu_run prototype from svm.c KVM: SVM: Add register operand to vmsave call in sev_es_vcpu_load KVM: x86/mmu: Optimize not-present/MMIO SPTE check in get_mmio_spte() KVM: x86/mmu: Use raw level to index into MMIO walks' sptes array KVM: x86/mmu: Get root level from walkers when retrieving MMIO SPTE KVM: x86/mmu: Use -1 to flag an undefined spte in get_mmio_spte() ...
