Subject: [patch 1/1] x86_64: Rename KDB_VECTOR to DEBUGGER_VECTOR
Date: Mon, 08 Aug 2005 12:27:10 -0700 [thread overview]
Message-ID: <resend.1.882005.trini@kernel.crashing.org> (raw)
CC: Andi Kleen <ak@suse.de>, Keith Owens <kaos@sgi.com>
The existing hook from KDB in the IPI code is really just a hook for the
NMI vector. We rename the vector thusly and then it's up to the
debugger to handle things from default_do_nmi().
