[PATCH 3/7] IPMI: documentation fixes

[Corey Minyard]

From: Corey Minyard <cminyard@xxxxxxxxxx>

Clean up IPMI documentation to remove references to high-res timers
and add info about the polling thread.  Also fix an doc error for a
parameter.

Not needed for the stable kernel.

+If your IPMI interface does not support interrupts and is a KCS or

 these interfaces suck.
 
 The driver supports a hot add and remove of interfaces.  This way,
 interfaces can be added or removed after the kernel is up and running.
