From 3afb209a43a4216ad4f1411922d47a44252926c6 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 14 Mar 2007 13:03:35 +0900 Subject: sh: Fix bogus regs pointer in do_IRQ(). SH-3 and SH-4 were trampling the register, and SH-2 wasn't even setting it in the first place. This ended up with some rather broken behaviour in the sysrq show_regs().
