  KVM: x86: allow KVM_REQ_GET_NESTED_STATE_PAGES outside guest mode for VMX (2021-01-25 18:54:09 -0500)

----------------------------------------------------------------
* 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

----------------------------------------------------------------
Alexandru Elisei (1):
      KVM: arm64: Use the reg_to_encoding() macro instead of sys_reg()

David Brazdil (1):
      KVM: arm64: Allow PSCI SYSTEM_OFF/RESET to return

Jay Zhou (1):
      KVM: x86: get smi pending status correctly

Like Xu (2):
      KVM: x86/pmu: Fix UBSAN shift-out-of-bounds warning in intel_pmu_refresh()
      KVM: x86/pmu: Fix HW_REF_CPU_CYCLES event pseudo-encoding in intel_arch_events[]

Lorenzo Brescia (1):
      kvm: tracing: Fix unmatched kvm_entry and kvm_exit events

Marc Zyngier (4):
      KVM: arm64: Hide PMU registers from userspace when not available
      KVM: arm64: Simplify handling of absent PMU system registers
      KVM: arm64: Filter out v8.1+ events on v8.0 HW
      KVM: Forbid the use of tagged userspace addresses for memslots

Maxim Levitsky (1):
      KVM: nVMX: Sync unsync'd vmcs02 state to vmcs12 on migration

Paolo Bonzini (2):
      Merge tag 'kvmarm-fixes-5.11-2' of git://git.kernel.org/.../kvmarm/kvmarm into HEAD
      KVM: x86: allow KVM_REQ_GET_NESTED_STATE_PAGES outside guest mode for VMX

Quentin Perret (1):
      KVM: Documentation: Fix spec for KVM_CAP_ENABLE_CAP_VM

Sean Christopherson (3):
      KVM: x86: Add more protection against undefined behavior in rsvd_bits()
      KVM: SVM: Unconditionally sync GPRs to GHCB on VMRUN of SEV-ES guest
      KVM: x86: Revert "KVM: x86: Mark GPRs dirty when written"
