Cover letter [PATCH 00/18] KVM: arm64: Prefix patches for NV support
As a bunch of the NV patches have had a decent amount of review, and given that they do very little on their own, I've put together a prefix series that gets the most mundane stuff out of the way.
Of course, nothing is functional, but nothing gets used either. In a way, this is pretty similar to the current state of pKVM! ;-)
Thanks,
M.
