Just send me a patch relative to today's linux-next (or merge
338eeb9b8318) and I will add it when I merge the kvm-arm tree on
Monday.  And don't forget to tell Linus :-)

Or you could merge commit 63afbe7a0ac1 ("kvm: arm64: vgic: fix hyp
panic with 64k pages on juno platform") from Linus' tree into the
kvm-arm tree (which is what Linus merged) and fix it up yourself - with
an appropriate comment explaining why it was done, of course.
