Subject: [RFC] MMU Notifier CL-pre-V4

Here is the full set for Andrea. This is the patchset that was posted for
internal SGI review (no additional fixes to mm_lock).


Changes vs. Andrea V12

- Comments to explain locking
- Merge missing EMM pieces
- Resequence patches
- Simplify mlock
- Deal with lock droppign in unmap_range
  (had to introduce rwsem_is_contended() for that)
- Update descriptions.

The most important piece that would be good to review is
the locking description in mmu_notifiers.h (the descriptions
are short they will not be included in the source).
