Sending this out again after incorporating the feedback from Yanmin
Zhang and Dave Hansen. Are we ready to go for -mm yet? The only patch
which has seen any recent changes is #2 below so I assume people agree
with #1 and #3 now :)
The three patches:
1) Remove a get_user_pages() optimization that is no longer valid for
demand faulting
2) Move fault logic from hugetlb_prefault() to hugetlb_pte_fault()
3) Apply a simple overcommit check so demand fault accounting behaves
in a manner in line with how prefault worked
Diffed against 2.6.13-git6
