Hi,

This patchkit:

- converts PIO code to use scatterlists instead of directly walking bios
- fixes longstanding 'data integrity on error' issue in non-taskfile PIO code
- unifies single/multiple PIO handling
- unifies taskfile/non-taskfile PIO handling

Changes:
- resync with -bk (first two patches are now merged)
- ide_sg_init() become generic init_sg_one() helper (linux/scatterlist.h)
  (thanks to Jeff and Jens for suggestions)
- use init_sg_one() in Etrax IDE driver
- bugfix: use sg->length instead of sg_dma_len(sg)
  (found thanks to rmk's concerns)
- uninline ide_pio_multi()
- make ide_pio_sector() and task_error() static
- drop removal of bio walking for now

Testing (esp. on non x86) and comments are welcomed.

BTW 'sanitize DMA' patchkit should be ready soon.

Bartlomiej
