Hi.

Your patch isn't SMP-safe.
domVTi code assumes that the p2m table is build at the domain creation and
read-only after that.
However your patch breaks the assumption and opened the door
to SMP world.
Especially you must resolve the race between tlb insert and tlb purge.
Do you have any plan to fix it?

thanks.
