Merge branch kvm-arm64/mops into kvmarm/next
* kvm-arm64/mops:
: KVM support for MOPS, courtesy of Kristina Martsenko
:
: MOPS adds new instructions for accelerating memcpy(), memset(), and
: memmove() operations in hardware. This series brings virtualization
: support for KVM guests, and allows VMs to run on asymmetrict systems
: that may have different MOPS implementations.
KVM: arm64: Expose MOPS instructions to guests
KVM: arm64: Add handler for MOPS exceptions
