[PATCH v2 01/13] powerpc/eeh: Add eeh_max_freezes to initial EEH log line
From: Sam Bobroff <hidden>

The current failure message includes the number of failures that have occurred in the last hour (for a device) but it does not indicate how many failures will be tolerated before the device is permanently disabled. Include the limit (eeh_max_freezes) to make this less surprising when it happens. Also remove the embedded newline from the existing message to make it easier to grep for.
