Merge branch kvm-arm64/misc into kvmarm/next

* kvm-arm64/misc:
  : Miscellaneous updates
  :
  :  - Convert CPACR_EL1_TTA to the new, generated system register
  :    definitions.
  :
  :  - Serialize toggling CPACR_EL1.SMEN to avoid unexpected exceptions when
  :    accessing SVCR in the host.
  :
  :  - Avoid quiescing the guest if a vCPU accesses its own redistributor's
  :    SGIs/PPIs, eliminating the need to IPI. Largely an optimization for
  :    nested virtualization, as the L1 accesses the affected registers
  :    rather often.
  :
  :  - Conversion to kstrtobool()
  :
  :  - Common definition of INVALID_GPA across architectures
  :
  :  - Enable CONFIG_USERFAULTFD for CI runs of KVM selftests
  KVM: arm64: Fix non-kerneldoc comments
  KVM: selftests: Enable USERFAULTFD
  KVM: selftests: Remove redundant setbuf()
  arm64/sysreg: clean up some inconsistent indenting
  KVM: MMU: Make the definition of 'INVALID_GPA' common
  KVM: arm64: vgic-v3: Use kstrtobool() instead of strtobool()
  KVM: arm64: vgic-v3: Limit IPI-ing when accessing GICR_{C,S}ACTIVER0
  KVM: arm64: Synchronize SMEN on vcpu schedule out
  KVM: arm64: Kill CPACR_EL1_TTA definition
