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
