From 7d2bd30f67e231920091d55d0fffc3a4bf43e68a Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 11 Oct 2006 02:06:59 -0500 Subject: [PATCH] [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.
