sh: __irq_entry annotate do_IRQ().
This adds an __irq_entry annotation for do_IRQ() so that the IRQ annotation in the function graph tracer works as advertized. We already have the IRQENTRY section wired up, so this is just a trivial addition to actually make use of it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
