Cover letter [PATCH 0/6] x86, UV2: BAU fixes for UV version 2

Following are 6 patches for using SGI's Altix UV2's Broadcast Assist Unit for TLB shootdown.

The first 3 patches are very necessary to using the BAU on this new hardware. Number 3 is a large one.

The last 3 are not so vital, but fairly trivial.
All have been fully tested.
