Looks good, I'm just uncertain about role.invalid handling. What's the
reasoning here?
Avi,
Thanks for your reply.
We no need worry about 'role.invalid' here, since we only allow the PTE shadow
pages(role.level == 1) become unsync, and in current code, 'role.invalid' is
only
used for root shadow pages.
Right, the invlpg change is not it yet. But I think it should be in
this patch; I don't like subtle dependencies, and it will make the
invplg patch simpler.
