[PATCH 0/5] Add TLB invalidation abstraction

[stuartsummers]

This is a new collection of patches from Matt that has
been floating around internally and on the mailing list.
The goal here is to abstract the actual mechanism of
the invalidation from the higher level invalidation triggers
(like page table updates).

Most of these were brought in unmodified by Matt, but
I've done some minor rebase work here and there and
added my signoff where those rebases seemed a little
more extensive.

This is built on top of [1] and [2]. I've also brought
in [3] and [4] individually from a separate series
from Matt.
