From ef23cdbefc3ab7f2ee9ee6dc6d4a94d7d6ec5e2b Mon Sep 17 00:00:00 2001 From: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Date: Mon, 17 Nov 2008 10:18:08 +0900 Subject: [PATCH] [IA64] use mprintk instead of printk, in ia64_mca_modify_original_stack Using printk from MCA/INIT context is unsafe since it can cause deadlock. The ia64_mca_modify_original_stack is called from both of mca handler and init handler, so it should use mprintk instead of printk.
