Add a new optional method, dev_ioctl, to the audio hardware driver interface.
...
It is called when an unrecognized ioctl() is performed on a device,
thus allowing ioctl()s that frob the hardware driver (like loading
microcode).

Back out previous. It is no longer needed, as both the Alpha
...
and DECstation IOASIC drivers clear the appropriate interrupts
in the dispatch routine.

Clear the DMA pointer reload interrupt bits in the IOASIC_INTR

register to prevent interrups from looping on the Alpha.

- Write the registers 7930 registers properly on the Alpha (it's
...
different than on the DECstation).
- Use IOASIC_DMA_BLOCKSIZE instead of PAGE_SIZE.
Should make this work on the Alpha. From discussion with
Izumi Tsutsui, Gregory McGarry, and Chris Demetriou, and
much reading of EK-D3SYS-PM.

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.
