sh: Add die chain notifiers. Add the atomic die chains in, kprobes needs these. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: nmi_debug support. This implements support for NMI debugging that was shamelessly copied from the avr32 port. A bit of special magic is needed in the interrupt exception path given that the NMI exception handler is stubbed in to the regular exception handling table despite being reported in INTEVT. So we mangle the lookup and kick off an EXPEVT-style exception dispatch from the INTEVT path for exceptions that do_IRQ() has no chance of handling. As a result, we also drop the evt2irq() conversion from the do_IRQ() path and just do it in assembly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

DIE_NMI,
sh: Wire up oops reporting in the die notifier chain. Commit 3f5a54e371ca20b119b73704f6c01b71295c1714 ("ftrace: dump out ftrace buffers to console on panic") added an ftrace buffer dumper that hooks in to the die notifier chain and dumps out data in the oops path. Unfortunately SH supported ftrace but didn't support DIE_OOPS, so add that in and get it building again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

DIE_OOPS,
sh: hw-breakpoints: Add preliminary support for SH-4A UBC. This adds preliminary support for the SH-4A UBC to the hw-breakpoints API. Presently only a single channel is implemented, and the ptrace interface still needs to be converted. This is the first step to cleaning up the long-standing UBC mess, making the UBC more generally accessible, and finally making it SMP safe. An additional abstraction will be layered on top of this as with the perf events code to permit the various CPU families to wire up support for their own specific UBCs, as many variations exist.

sh: Tidy up and generalize page fault error paths. This follows the x86 changes for tidying up the page fault error paths. We'll build on top of this for _32/_64 unification. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
