Merge tag 'for-linus-4.8' of git://git.code.sf.net/p/openipmi/linux-ipmi

Pull IPMI updates from Corey Minyard:
 "Remove some old cruft that was disabled by default a long time ago.

  No modern hardware should need this, and anybody who really doesn't
  have something to automatically detect IPMI can add the device by hand
  on the module commandline or hot add it"

  ipmi: remove trydefaults parameter and default init

Currently, only KCS and SMIC are supported. If
you are using IPMI, you should probably say "y" here.

Modern systems will usually expose IPMI interfaces via a discoverable
firmware mechanism such as ACPI or DMI. Older systems do not, and so
the driver is forced to probe hardware manually. This may cause boot
delays. Say "n" here to disable this manual probing. IPMI will then
only be available on older systems if the "ipmi_si_intf.trydefaults=1"
boot argument is passed.
