2008-09-08sh: kprobes: Default to NOTIFY_DONE for unhandled debug traps.Paul Mundt1-1/+1
Presently this is doing a force_sig() SIGTRAP, which is already taken care of in the generic code if no one asserts NOTIFY_STOP. Switch the default return to NOTIFY_DONE in the case of unhandled traps, so that the same trap may pass through to other users on the same die chain. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Not all parts support trapa #0xff, so use something within the debug trap range that's accessible on all parts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
