The Corrected Machine Check structure (CMC) in HEST has a flag which can be set by the firmware to indicate to the OS that it prefers to process the corrected error events first. In this scenario, the OS is expected to not monitor for corrected errors (through CMCI/polling). Instead, the firmware notifies the OS on corrected error events through GHES. Linux already has support for GHES. This patch adds support for parsing CMC structure and to disable CMCI/polling if the firmware first flag is set. Further, the list of machine check bank structures at the end of CMC is used to determine which MCA banks function in FF mode, so that we continue to monitor error events on the other banks.
