AD1845 on my AlphaStation 255 doesn't match the AD1845 doc.
...
Try to detect AD1845 (unfortunately this is not always correct)
and work around the problems.

Use separate interrupt handlers for play and record the chip has
...
support for it and we're configured for separate play and record
DRQs. This makes full-duplex audio work on the Windows Sound System
(found in many Alpha systems).

Change the kernel mmap interface so that the offset to map is an
...
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

of ISA DMA use this call to determine their maximum transfer size.
