Jeff,

The PIO fixes revised according to the previous reviews.

1/3 pio1.diff:
   - Modify the "if conditions" in __atapi_pio_bytes() to be more robust.

2/3 pio2.diff:
   - Add ATA_FLAG_IO_32BIT to libata.h for hosts with 32-bit data register.
   - Modify ata_mmio_data_xfer() and ata_pio_data_xfer() to handle buffer with length
     not aligned to 32-bit boundary.

3/3 pio3.diff:
   - Modify __atapi_pio_bytes() to handle the case when device returns/needs extra data.

(Patch diff'ed against 2.6.13-rc4 tree, 02459eaab98a6a57717bc0cacede148fc76af881)

Tested ok on x86 with Promise PDC20275 and LG DVD-Multi drive.

For your review and advice, thanks.

Albert
