sommerfeld 851de295eb Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

simonb 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.

kleink 1e9bb239a3 Off-by-one error in limiting the DMAC buffer size for Audio 2 to 64K (actually
64K - 1); from Dave Sainty in PR kern/9064.

kleink c88b5146dc Add support code to have the Hardware Volume Control interact with the
software mixer Master Volume state in a defined way by lazily updating the
latter if input from the former was processed.

augustss 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.

cgd c3703ecfdd don't print using string pointer one off the end of the eso_rev2model
array.  pointed out by Kouichi Hashikawa in PR#8601.

kleink bb54953b63 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.  :-)

Let the mpu device attach at the sb device, and then midi at the mpu.
Update the mpu at eso attachment.

augustss cbf1f6f1b9 Move the MPU driver isa/ to ic/.
(I didn't move it in the repository because the revision history
is very short and uninteresting. :)
