Pull IPMI updates from Corey Minyard:
"Minor bug fixes for the IPMI driver

There was a bug in the SSIF driver where in certain conditions it
could stop working.

Outside of that: spelling fixes, removing some dead code, re-adding a
missing statistic increment, and removal of register_sysctl_table()"
