Thanks for your reply.
This patch can be used by both guests and hosts.
I have tested it on imx8qm platform(both guest and host are ARM64 architecture), and it works well.
So I guess Intel MIC won't meet big problems when both guest and host apply this patch. But it is best if it can be tested.

Best regards
Sherry
