Subject: [PATCH] x86: UV BAU interrupt vector duplicated
Date: Fri, 11 Dec 2009 11:36:18 -0600 [thread overview]
Message-ID: <E1NJ9Pe-0004P7-0Q@eag09.americas.sgi.com> (raw)
From: Cliff Wickman <cpw@sgi.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().
