Log:
Stop physical DMA for the non-auto case in isa_dmadone(). This fixes a
small part of a bug suite beginning in the SLICE probes but mostly in the
floppy driver. This is a quick fix: the auto case shouldn't be special;
DMA should also be stopped in isa_dma_release(); isa_dmastop() probably
shouldn't exist; common DMA registers should not be accessed without
locking.
