[PATCH] SCSI on non-ISA systems

[Geert Uytterhoeven]

Since 2.5.31, the compilation of kernel/dma.c is conditional on
CONFIG_GENERIC_ISA_DMA. However, drivers/scsi/hosts.c unconditionally calls
free_dma(), which breaks machines with SCSI that don't have ISA.

Please apply!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
