Subject: [PATCH] x86: UV BAU interrupt vector duplicated

From: Cliff Wickman <cpw@....com>

Diffed against 2.6.32

Interrupt vector 0xec has been doubly defined in irq_vectors.h

It seems arbitrary whether LOCAL_PENDING_VECTOR or UV_BAU_MESSAGE is
the higher number.  As long as they are unique.
If they are not unique we'll hit a BUG in alloc_system_vector().
