From: Rik van Riel on
Andrew, here are the patches to always lock the root anon_vma,
ported to the latest -mm tree.

These patches implement Linus's idea of always locking the root
anon_vma and contain all the fixes and improvements suggested
by Andrea.

This should fix the last bits of the anon_vma locking.

v3 is identical to v2, except I gathered up the Acked-by:s that
were on list already.

Patches 4 and 5 still need some reviewing and acks...
