Why doesn't this file define 29, 30, 31 bit DMA masks, required by many

your mail unfortunately was not in diff -u form ;)
I'm pretty sure that such constants are welcome


OK, I just wanted to see if there was a reason before posting it.

Anyone know of hardware that needs less than a 29 bit mask?


ALS2000 sound device, which is basically an ISA SB chip on a PCI board.

ALS4000, excuse me.
