Andre,

We spoke a while back about a GET/SET BUSSTATE API for IDE.  Attached is my
(very simple) patch adding 2 ioctls, and obsoleting 1.  I will send the
implementation of this for the HPT370 in a different message.  Please let
me know if there are any problems with this preventing general inclusion.

This patch also includes support for a configurable 'max failures'
parameter, and one change for better DMA error reporting.
