Subject: [PATCH v2 0/2] Add DIMM 2x refresh event and failure syndrome

Adds event_dimm_2x_refresh sysfs to report doubling of DIMM refresh
rate on high temperature condition and event_dimm[0-15]_syndrome sysfs
to report the DDR failure syndrome to BMC when DIMM training failed.

Discussion for v1:
