From b652c23cb0f7808bedb5442c416d91705a465c67 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 8 Dec 2006 17:46:29 +0900 Subject: [PATCH] sh: Fix get_wchan(). Some time ago the schedule frame size changed and we failed to reflect this in get_wchan() at the time. This first popped up as a problem on SH7751R where schedule_frame ended up being unaligned and generating an unaligned trap. This fixes it up again..
