Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm fixes from Paolo Bonzini: - x86 bugfixes - Documentation fixes - Avoid performance regression due to SEV-ES patches - ARM: - Don't allow tagged pointers to point to memslots - Filter out ARMv8.1+ PMU events on v8.0 hardware - Hide PMU registers from userspace when no PMU is configured - More PMU cleanups - Don't try to handle broken PSCI firmware - More sys_reg() to reg_to_encoding() conversions * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: KVM: x86: allow KVM_REQ_GET_NESTED_STATE_PAGES outside guest mode for VMX KVM: x86: Revert "KVM: x86: Mark GPRs dirty when written" KVM: SVM: Unconditionally sync GPRs to GHCB on VMRUN of SEV-ES guest KVM: nVMX: Sync unsync'd vmcs02 state to vmcs12 on migration kvm: tracing: Fix unmatched kvm_entry and kvm_exit events KVM: Documentation: Update description of KVM_{GET,CLEAR}_DIRTY_LOG KVM: x86: get smi pending status correctly KVM: x86/pmu: Fix HW_REF_CPU_CYCLES event pseudo-encoding in intel_arch_events[] KVM: x86/pmu: Fix UBSAN shift-out-of-bounds warning in intel_pmu_refresh() KVM: x86: Add more protection against undefined behavior in rsvd_bits() KVM: Documentation: Fix spec for KVM_CAP_ENABLE_CAP_VM KVM: Forbid the use of tagged userspace addresses for memslots KVM: arm64: Filter out v8.1+ events on v8.0 HW KVM: arm64: Compute TPIDR_EL2 ignoring MTE tag KVM: arm64: Use the reg_to_encoding() macro instead of sys_reg() KVM: arm64: Allow PSCI SYSTEM_OFF/RESET to return KVM: arm64: Simplify handling of absent PMU system registers KVM: arm64: Hide PMU registers from userspace when not available
