[POWERPC] ppc: Add missing calls to set_irq_regs
In the timer_interrupt we were not calling set_irq_regs() and if we are profiling we will end up calling get_irq_regs(). This causes bad things to happen. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
