From 444d2921215ae6c21f90eb5fa5d03f784f84f1aa Mon Sep 17 00:00:00 2001 From: "Kai.Jiang" Date: Tue, 26 Jul 2011 16:08:49 -0700 Subject: drivers/edac/mpc85xx_edac.c: correct offset_in_page mask bits in edac_mc_handle_ce() Parameter offset_in_page in edac_mc_handle_ce() should mask the higher bits above the page size, not the lower bits. The original input sometimes causes a crash. Signed-off-by: Kai.Jiang Signed-off-by: Shaohui Xie Cc: Anton Vorontsov Cc: Grant Likely Cc: "David S.
