Subject: [patch 07/16] x86_64: Rename KDB_VECTOR to DEBUGGER_VECTOR
Date: Mon, 29 Aug 2005 09:10:18 -0700 [thread overview]
Message-ID: <resend.7.2982005.trini@kernel.crashing.org> (raw)
In-Reply-To: <resend.6.2982005.trini@kernel.crashing.org>
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 do_default_nmi().
