Merge branch kvm-arm64/ffa-1.2 into kvmarm-master/next
* kvm-arm64/ffa-1.2:
: .
: FFA 1.2 support for pKVM, courtesy of Per Larsen.
:
: From the cover letter at [1]:
:
: "The FF-A 1.2 specification introduces a new SEND_DIRECT2 ABI which
: allows registers x4-x17 to be used for the message payload. This patch
: set prevents the host from using a lower FF-A version than what has
: already been negotiated with the hypervisor. This is necessary because
: the hypervisor does not have the necessary compatibility paths to
: translate from the hypervisor FF-A version to a previous version."
