The CPER error record has a reset bit that indicates that the platform has reset the bus. The reset bit can be set for any severity error including recoverable. From the AER code path's perspective, any error is fatal if the bus has been reset. This patch upgrades the severity of the AER recovery to AER_FATAL whenever the CPER error record indicates that the bus has been reset. Changes since v1: Fixed a typo in comment. Changes since v2: Set the aer_severity to AER_FATAL rather than using cper_severity_to_aer(). Simplified the comment.
