889c658b5b 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.

860ebb7a92 Make little endian and big endian version of all functions
that deal with 16 bit samples.  Let the drivers decide which ones
to use.

2422638ad5 Fix a buglet in the driver's DMA buffer list ipmlementation, causing the next-
in-list (wrong) descriptor structure of the buffer in question to be freed.

bd4cd051b9 This is an utterly revolting hack to work around the previously mentioned
lossage.  On the Alpha, we force the buffers to be allocated through the SGMAP
so that the PCI bus addresses are low enough.
At least it's only one line of code...

699a815751 Pass the correct address (PCI bus address, not PA) to the card.
Also fix some typos and add more debugging printf()s.
This would work on the Alpha, but the card I have appears to have the upper
address bits chopped off, and the ring buffer gets mapped using the DGMAP,
which uses the upper bits.  Boom.

f1e84a4ec5 A few things:
* Use the trigger interface.
* Permit different encodings for record and playback.
* Set AUDIO_PROP_INDEPENDENT.
* Fix the mmap(2) hole again.
* Use 16-bit mode for a-law and u-law playback.

e5f5e628d2 Pass the direction to the allocm and round_buffersize methods.
Some drivers need this to properly allocate DMAable memory.

b94cb7b768 Add a driver for the S3 SonicVibes chip. From OpenBSD and
Constantine Paul Sapuntzakis (csapuntz@cvs.openbsd.org) with
some changes by me.
XXX The driver still needs work.
