Hi, Len, This is used by APEI ERST and GEHS. But it is a generic hardware error reporting mechanism and can be used by other hardware error reporting mechanisms such as EDAC, PCIe AER, Machine Check, etc. The patchset is split from the original APEI patchset to make it explicit that this is a generic mechanism, not APEI specific bits.
