Attached is a patch that adds a fallback polling mechanism for
retrieving CPE logs from firmware.  The code makes an attempt to
determine if CPEs are happening and adjust the polling interval
accordingly.  On a system that's not getting CPEs, it should
poll every 15 minutes, so should have no performance impact.

   HP zx1 systems do not support an interrupt driven CPE notifier,
so polling is required to get these logs.  Comments?  Thanks,

	Alex
