Subject[PATCH] [7/28] x86: MCE: Log corrected errors when panicing
Date

Impact: bugfix

Normally the machine check handler ignores corrected errors and leaves
them to machine_check_poll(). But when panicing mcp won't run, so
log all errors.

Note: this can still miss some cases until the "early no way out"
patch later is applied too.
