	sys/dev/isa/isareg.h: revision 1.10
	sys/dev/isa/isadma.c: revision 1.67

fix off-by-one in the mapping of the ISA DMA page registers, they actually
start at 0x81; the code used bus_space_map() starting from 0x80 but
used +1 offset for actual I/O, now it maps starting 0x81 and does I/O
without offset

the reads and writes work exactly the same as before, but this frees
0x80 for being mapped independantly
patch provided in PR kern/52468 by Jonathan Chapman; checked against the spec
and also FreeBSD sys/x86/isa/isa_dma.c

isadma.c: #if 0 some diagnostic code that compares two bus_space_tag_t's.

pcdisplay.c: #if 0 some code that compares two bus_space_tag_t's
    in order to see if pcdisplay0 is console.  It does not seem to
    be helpful to compare the tags; maybe the author intended to
    compare some other bus property?

MI code should not compare an opaque type such as bus_space_tag_t!

Let us safely detach the ISA bus and devices attaching to the ISA
bus:

1 Add isadetach() for detaching the ISA bus, and add some helper
  routines that release resources held for ISA DMA.

2 In isachilddetached(), forget references to child devices.

While I am here, change ISA_DMA_DRQ_ISFREE(...) == 0 to the simpler
expression, !ISA_DMA_DRQ_ISFREE(...).

A few ISA sound drivers like to share dma channels, and hence deferred
isa_dmamap_create() calls to their open/close entrypoints. This worked
with some luck, but broke on i386 when _bus_dmamap_create started
to allocate bounce buffers upfront, since memory below 16M may well
not be available when the sound devices is opened for the Nth time.

To fix this, create a new simple interface, isa_drq_alloc/isa_drq_free,
wrappers around already existing bitmask macros. These are expected
to be used before an isa_dmamap_create call, and after an
isa_dmamap_destroy call, respectively. For the sb and ad1848 drivers,
they're deferred until open/close.

All isa_dmamap_create calls can now use BUS_DMA_ALLOCNOW and be done
at attach time.

Add extensible malloc types, adapted from FreeBSD.  This turns
malloc types into a structure, a pointer to which is passed around,
instead of an int constant.  Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.

Change the kernel mmap interface so that the offset to map is an

Audio: Remove the machine dependant code I put in audio.c by mistake.
This adds another method to audio_hw_if.  Also remove a field from
audio_hw_if that was not read-only.

Changes to the sudio system:
  - It is now possible to handle devices that want "looping" DMA,
    e.g. the SoundBlaster correctly.  The WSS and SB drivers use this.
    To do this several new methods were introduced in audio_hw_if.
  - Different silence handling (forced by previous change).
  - The audio driver can now be mmap()-ed, but due to problems in
    the VM system only for writing for now.
  - The OSS (Linux) audio emulation takes advantage of some of the
    new features.

Add isa_dmamem_*() functions, which are wrappers around bus_dmamem_*()
functions, but encapsulate the peculiar memory contraints of the
on-board ISA DMA controller.  Devices which use the isa_dma*() functions
should use these for DMA-safe memory manipulation.

Mostly-rewrite, converting the ISA DMA controller driver to be a user
