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 Signed-off-by: Oliver Upton <oliver.upton@linux.dev>
