At present the MRC cache on ivybridge is disabled due to a bug which was unknown. This has now been located and a fix is included in this series. In addition, the RTC functions have a few problems which prevent the checksum from being read correctly. This series fixes these and adds a few other minor improvements.
Also included is a modified version of Bin's patch to enable the MRC cache on ivybridge.
