Merge branch kvm-arm64/dirty-log-ordered into kvmarm-master/next
* kvm-arm64/dirty-log-ordered:
: .
: Retrofit some ordering into the existing API dirty-ring by:
:
: - relying on acquire/release semantics which are the default on x86,
: but need to be explicit on arm64
:
: - adding a new capability that indicate which flavor is supported, either
: with explicit ordering (arm64) or both implicit and explicit (x86),
: as suggested by Paolo at KVM Forum
:
: - documenting the requirements for this new capability on weakly ordered
: architectures
:
: - updating the selftests to do the right thing
: .
KVM: selftests: dirty-log: Use KVM_CAP_DIRTY_LOG_RING_ACQ_REL if available
KVM: selftests: dirty-log: Upgrade flag accesses to acquire/release semantics
KVM: Document weakly ordered architecture requirements for dirty ring
KVM: x86: Select CONFIG_HAVE_KVM_DIRTY_RING_ACQ_REL
KVM: Add KVM_CAP_DIRTY_LOG_RING_ACQ_REL capability and config option
KVM: Use acquire/release semantics when accessing dirty ring GFN state
