There are lots of code changes here for a single patch but as you have
mentioned shared KVM bits would have prevented splitting arm and arm64
changes into separate patches. Just curious, are you planning to respin
this patch sooner after fixing the reported build problems caused by
missing p4d_offset_kimg() and p4d_sect() definitions ?
