#     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
