The following commit has been merged in the linux branch: commit ba93483f8c997f1a3fc0a6677f41e8556ae3eba6 Author: Paul Mundt lethal@linux-sh.org Date: Mon Oct 26 09:58:31 2009 +0900
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.
