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.

software mixer Master Volume state in a defined way by lazily updating the
latter if input from the former was processed.

Since the Audio 1 DMA controller implements the 24 low address bits only,
...
add the gross hack originally implemented by Charles Hannum in the SonicVibes
driver to force allocation of DMA memory for that channel through the Scatter-
Gather Map to get an address range that fits in.
The eso driver now works on Alphas except for DWLPX-based systems, whose owners
are not likely to desire audio or likely can afford slightly less cheap audio
hardware. :-)
