Date: Wed, 11 Oct 2006 02:06:59 -0500 (CDT) From: Kumar Gala <galak@...nel.crashing.org> To: Linus Torvalds <torvalds@...l.org>, Paul Mackerras <paulus@...ba.org> cc: linux-kernel@...r.kernel.org, <linuxppc-dev@...abs.org> Subject: [PATCH] ppc: Add missing calls 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.
