Heh, that's helping me a lot and makes get_one_user_page very
simple again (and simplify the follow_huge_* stuff even more).
This could help futex slow-path and remove loads of code.
Once this hugetlb stuff settles down a bit, I'll rewrite the
page-walking again to accomodate this. No API changes, just
internal rewrites.
So please tell the linux-mm list, when it's finished and I'll have
sth. ready for -mm in the first week of March[1].

Ingo Oeser
