From bc09effabf0c5c6c7021e5ef9af15a23579b32a8 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 8 Dec 2009 11:21:37 +0900 Subject: x86/mce: Set up timer unconditionally mce_timer must be passed to setup_timer() in all cases, no matter whether it is going to be actually used. Otherwise, when the CPU gets brought down, its call to del_timer_sync() will never return, as the timer won't have a base associated, and hence lock_timer_base() will loop infinitely.
