[PATCH 03/12] mce-severity: cleanup severity table

Hidetoshi Seto
2011-05-27T04:05:34Z

Current format of item in this table is:
condition(param, ..., level, message [, condition2 ...])

So we have to check both of head and tail of the item to know
conditions to match the item.

Make them in straight forward form:
item(level, message, condition [, condition2 ...])
