From 26c3c283c5b08dd250279c06ba3ab5b094bbacc3 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 19 Jul 2012 13:59:39 -0400 Subject: x86: mce: Split timer init Split timer init function into the init and the start part, so the start part can replace the open coded version in CPU_DOWN_FAILED.
