[PATCH] 32-bit compatibility HDIO IOCTLs 

A couple of HDIO IOCTLs are not yet handled and a few others are marked
as using a pointer rather than an unsigned long.  The formers include:

HDIO_GET_WCACHE, HDIO_GET_ACOUSTIC, HDIO_GET_ADDRESS and
HDIO_GET_BUSSTATE.  The latters are: HDIO_SET_MULTCOUNT,
HDIO_SET_UNMASKINTR, HDIO_SET_KEEPSETTINGS, HDIO_SET_32BIT,
HDIO_SET_NOWERR, HDIO_SET_DMA, HDIO_SET_PIO_MODE and HDIO_SET_NICE.

Additionally 0x330 used to be HDIO_GETGEO_BIG and may be issued by 32-bit
`hdparm' run on a 64-bit kernel making Linux complain loudly.

This is a fix for these issues.
