Subject[049/136] x86: SGI UV: Fix IPI macros
2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Jack Steiner <steiner@sgi.com>

commit d2374aecda3f6c9b0d13287027132a37311da300 upstream.

The UV BIOS has changed the way interrupt remapping is being done.
This affects the id used for sending IPIs. The upper id bits no
longer need to be masked off.
