v1->v2:
  Patch 5 and 7 are added based on Paolo's suggestions.
  Patch 8-10 are new.

Patch 1/2/3/4: no change.
Patch 5: Needed a bit more work than I had expected.
Patch 6: Removed extra comment of v1 (patch 5 made it inappropriate).
Patch 7: As expected, many places needed to be converted.
Patch 8: This is new, but only a small change.

Patch 9: Kind of an RFC (though I have checked it to some extent).
  Following two places need to be carefully checked:
  - in kvm_mmu_get_page: "if (!direct)" block after kvm_mmu_alloc_page()
  - in FNAME(fetch): "if (FNAME(gpte_changed)(vcpu, gw, it.level - 1))" case
Patch 10: Trivial cleanup, assuming that patch 9 is correct.


In summary: patch 1-7 is the result of updating v1 based on the suggestions.
  Although patch 5 does not look so nice than expected, this is the most
  conservative approach, and patch 8-10 try to alleviate the sadness.
