# Commit 6a2c6a68423475cd89a8cc9978554880e5a21b7d # Date 2017-04-07 15:56:09 +0200 # Author Haozhong Zhang <haozhong.zhang@intel.com> # Committer Jan Beulich <jbeulich@suse.com> x86/mce: always re-initialize 'severity_cpu' in mcheck_cmn_handler() mcheck_cmn_handler() does not always set 'severity_cpu' to override its value taken from previous rounds of MC handling, which will interfere the current round of MC handling. Always re-initialize it to clear the historical value.
