I think this patch together with the second one could go through the kvm
tree. For the core arm64 part:

Suzuki Poulose posted a patch that adds generic support for ARMv8 KVM 
targets.  I want to drop my second patch, so can we pick up this first 
patch through the ARM tree?

So if the second patch is no longer needed, what's using this patch? I
would defer merging it until actually required in some part of the
kernel.

Fair enough.
