Linus,

I sent this yesterday but I cannot find it in the archives (weird),
so I am resending it.

The following changes since commit 7c53f6b671f4aba70ff15e1b05148b10d58c2837:

  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

----------------------------------------------------------------

      KVM: arm64: Use the reg_to_encoding() macro instead of sys_reg()

      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):
