To pick the changes from:

  2cde51f1 ("KVM: arm64: Hide KVM_REG_ARM_*_BMAP_BIT_COUNT from userspace")
  b22216e1 ("KVM: arm64: Add vendor hypervisor firmware register")
  428fd678 ("KVM: arm64: Add standard hypervisor firmware register")
  05714cab ("KVM: arm64: Setup a framework for hypercall bitmap firmware registers")
  18f3976f ("KVM: arm64: uapi: Add kvm_debug_exit_arch.hsr_high")
  a5905d6a ("KVM: arm64: Allow SMCCC_ARCH_WORKAROUND_3 to be discovered and migrated")

That don't causes any changes in tooling (when built on x86), only
addresses this perf build warning:

  Warning: Kernel ABI header at 'tools/arch/arm64/include/uapi/asm/kvm.h' differs from latest version at 'arch/arm64/include/uapi/asm/kvm.h'
  diff -u tools/arch/arm64/include/uapi/asm/kvm.h arch/arm64/include/uapi/asm/kvm.h
