ERST is a way provided by APEI to save and retrieve hardware error record to and from some simple persistent storage (such as flash). The Linux kernel support implementation is quite simple and workable in NMI context. So it can be used to save hardware error record into flash in hardware error exception or NMI handler, where other more complex persistent storage such as disk is not usable. After saving hardware error records via ERST in hardware error exception or NMI handler, the error records can be retrieved and logged into disk or network after a clean reboot. For more information about ERST, please refer to ACPI Specification version 4.0, section 17.4. This patch incorporate fixes from Jin Dongming.
