29 * This file contains special code dealing with the DMA interface
32 * The DMA circuitry requires some special treatment for the peripheral
33 * devices which make use of the ST's DMA feature (the hard disk and the
35 * All devices using DMA need mutually exclusive access and can follow some
40 * st_dmagrab: ensure exclusive access to the DMA circuitry
41 * st_dmafree: free exclusive access to the DMA circuitry
42 * st_dmawanted: somebody is queued waiting for DMA-access
43 * dmaint: DMA interrupt routine, switches to the current driver
45 * st_dmaaddr_get: get address of last DMA-o
