Also, don't mark hugepages as all PageReserved any more.  That's preenting
callers from doing proper refcounting.  Any code which does a user pagetable
walk and hits part of a hugepage will now handle it transparently.

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.

OK...

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].

Well I'm thinking of renaming it to hugebugfs.  It should be settled down
shortly.
