Log Message:
Pull up revision 1.10 (requested by thorpej in ticket #2072):
- When starting an ATA or ATAPI transfer, handle the case where
(*dma_init)()
returns EINVAL, indicating that DMA cannot be done for this
transfer.
Fall back to PIO in this case.
- Add a geodeide_dma_init() routine that checks to make sure that
transfers
start on a 16 byte boundary, returning EINVAL if not.  Works
around a chip
bug that causes a hard system hang.
Problem reported and patch tested by Erik Fair.
