This is a nice cleanup.  The one minor comment I have is that since
power7_restore_hyp_resource has some unusual entry requirements (such
as requiring cr3 to be set a certain way), those requirements should
be documented in the comment just about the function entry point.  I
didn't see any unusual exit conditions, but if there are any they
should be documented too.
