[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. Signed-off-by: Maciej W.
