[PATCH] [16/21] SCSI-ISA-DMA: Remove automatic block layer bouncing for unchecked_isa_dma

[Andi Kleen <andi@xxxxxxxxxxxxxx>]

All ISA drivers explicitely tell the block layer now that it needs
to bounce for them, so SCSI mid layer doesn't need to do that automatically
for unchecked_isa_dma anymore.
