Merge branch 'ipmi' (emailed ipmi fixes)

Merge ipmi fixes from Corey Minyard:
 "Things collected since last kernel release.

  Some of these are pretty important.  The first three are bug fixes.
  The next two are to hopefully make everyone happy about allowing
  ACPI to be on all the time and not have IPMI have an effect on the
  system when not in use.  The last is a little cleanup"
