| |
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
From: Cliff Wickman <cpw@sgi.com>
commit 1d865fb728bd6bbcdfbd6ec1e2b8ade3b4805641 upstream.
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().
