Hi Greg,
Today's linux-next merge of the driver-core tree got a conflict in
arch/x86/kernel/traps.c, arch/x86/kernel/traps_32.c and
arch/x86/kernel/traps_64.c between various commits from Linus' tree and
commit 9f3c643d0d55424a469a28d463a2ae74a16ba721 ("sysfs: crash
debugging") from the driver-core tree.
The two traps_{64,32}.c files have been merged into the traps.c file but
the code modified by the driver-core patch has been moved to dumpstack_
{64,32}.c anyway.
I applied the following patch.
Time to update.
