Subject: [PATCH] x86: Use helper in fault_64.c
Date: Tue, 18 Dec 2007 02:58:55 -0800 [thread overview]
Message-ID: <1197975535.7734.21.camel@brick> (raw)
Use the fixup_exception() helper in fault_64.c
Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com>

This is only appropriate if CONFIG_PNP_BIOS cannot be set on
X86_64, which looks to be the case, but needs confirmation.
