. remove some unused variables
. declare worminit() right this time, it's actually extern (?)
. use wormminphys(), now that it's already there (hope i've got this right)
chipset. This does not attempt to do anything special with the timing
on the hope that the BIOS will have done the right thing already. The
actual interface from the wd driver to the new facility is not
implemented yet (this commit being an attempt at prodding someone else
to do it because looking at the wd driver always confuses the h*** out of me).
tape_umask=017 for all tapes. This has a significant effect only
for ft and st (they were created with the wrong umask 002 and then
chmod'ed to mode 640; now they are created with mode 660).
Chmod the st control devices (mode 3) to 600. These need to be
more secure than the st i/o devices, but were less secure.
Use the default umask of 077 for joy0. 002 gave mode 664, which
is insecure.
Use umask 037 for ch*. Cosmetic.
Removed redundant chmod's.
Sorted case lists for disks.
Also declared worminit() to avoid a compiler warning. Seems that the
other SCSI drivers don't declare XXinit() yet, so perhaps we'd also
create a typedef for these func's.
includes a hack in the probe code: the 82371FB is a multifuction
device, but doesn't properly set the configuration bit which
indicates this. So, we just hard-wire all 82371FBs as multifunction
devices.
This does not actually make the bus-master IDE stuff work, although
if anyone wants to work on that, I have the databooks that tell
how to use it.
The worm driver is alpha-usable! I've stuffed everything that is
needed into the kernel driver, including the logic to select
between different vendor's quirks.
Disclaimer: this has by now _only_ been tested on a heavily tweaked
2.0.5R system. I've done my best to retrofit it into -current, but
i don't have a chance yet to test it in a -current environment.
First attempt at creating devfs entries for sliced devices. Doesn't
quite work yet, so the heart of it is disabled.
Added bdev and cdev args to dsopen().
Create devfs entries in dsopen() and (unsuccessfully) attempt to make
them go away at the right times. DEVFS is #undefed at the start so
that this shouldn't cause problems.

drivers:
Fixed device names, links, minor numbers and modes.
wd.c:
Started actually supporting devfs.
diskslice.h:
Added devfs tokens to structs (currently 576 of them per disk! :-().
subr_diskslice.c:
Create devfs entries in dsopen() and (unsuccessfully) attempt to make
them go away at the right times. DEVFS is #undefed at the start so

fd and wt drivers need bounce buffers, so this normally saves 32K-1K
of kernel memory.
Keep track of which DMA channels are busy. isa_dmadone() must now be
called when DMA has finished or been aborted.
Panic for unallocated and too-small (required) bounce buffers.
fd.c:
There will be new warnings about isa_dmadone() not being called after
DMA has been aborted.
sound/dmabuf.c:
isa_dmadone() needs more parameters than are available, so temporarily
use a new interface isa_dmadone_nobounce() to avoid having to worry
about panics for fake parameters. Untested.
overrun by 2 pages.
Fixed the (unused) values returned from device attach functions.
Fixed checking of unit number in device open functions - don't load bad
pointers or print error messages about the contents of bad pointers.
Removed unused #includes.
asc.c:
Fixed premature setting of flags in ascopen() - copied the better order
in gscopen().
gsc.c:
Fixed conflict handling for drq:
- fail the probe if the configured drq doesn't match the actual drq.
- set the configured drq to match the actual drq in the autoconfig case.

way to avoid crossing a 64K DMA boundary was to specify an alignment
greater than the size even when the alignment didn't matter, and for
sizes larger than a page, this reduced the chance of finding enough
contiguous pages. E.g., allocations of 8K not crossing a 64K boundary
previously had to be allocated on 8K boundaries; now they can be
allocated on any 4K boundary except (64 * n + 60)K.
Fixed bugs in vm_alloc_page_contig():
- the last page wasn't allocated for sizes smaller than a page.
- failures of kmem_alloc_pageable() weren't handled.
Mutated vm_page_alloc_contig() to create a more convenient interface
named contigmalloc(). This is the same as the one in 1.1.5 except
it has `low' and `high' args, and the `alignment' and `boundary'
args are multipliers instead of masks.
of limited utility. In their place, add bunch of pointers
which will eventually be needed by the polled-interrupt scheme we're working
here. (It will probably be a while before the code is written and
committed here.) At the same time, a `void *if_softc' field
was added to the beginning of the structure to make certain driver
writers happier.
The practical upshot of all this is that you need to
recompile utilities such as netstat which manipulate struct ifnet.
