Pull IPMI updates from Corey Minyard:
 "Bug fixes and enhancements for IPMI

  This fixes a number of small bugs, but has some more major changes:

   - Loongson-2K BMC support is added. This is an MFD device and is
     dependent on the changes coming from that tree.

     The way the driver handles BMCs that have become non-functional has
     been completely redone. A number of changes in the past have
     attempted to handle various issues around this, but nothing has
     been very good. After working with some people on this, the code
     has been reworked to disable the driver and fail all pending
     operations if the BMC becomes non functional. It will retry the BMC
     once a second to see if it's back up"
