clock_attach() time (for now).
This removes our dependance on the DraCo ROM access timing and frees
the second CIA on Amigas.
b) support for DraCo rev. >= 4 native timer chips.
* When we are transferring in DATA (in asc_dma_in) and the target
is an async device, there is sometimes an extra byte in the FIFO.
If so, we need to drain that byte out of the fifo, but if and only
if the target is async. See also the comments in asc_dma_in()
in the related Mach mk84 asc driver (scsi_53C94_hdw.c), which
has an identical fix but applied in more restrictive conditions
than we need, with async *disk* targets, as well as async tapes.
* Add a watchdog and timeout active SCSI requests, to eliminate any
potential for deadlock due to applying the fix above on newer
silicon versions of the 53c94 which may not have the above problem.
Should use the MI scsi per-target timeout instead, when available.
for a level 6 interrupt. An interrupt only occurs if IR is set, and IR is
only set if the individual mask bits are set. The individual interrupt
status bits can be set without causing an interrupt if the corresponding
enable bits are not set.

to our version of gdb. I had to do it by hand, but every thing
works fine now. I changed ns32k-pinsn.c to use the xxx_filtered
functions.
* Added functions to ns32k-nat.c to support gdb -k with crash dumps.
* Made stacktracebacks work better with execs not compiled with -g.
NOTE: THESE FILES ARE NOW IDENTICAL TO THEIR ALPHA COUNTERPARTS.
The C preprocessor does the Right Thing when these files are built
on a SPARC. This makes it significantly easier to diff the two
versions (until a real MI 53c9x driver is done, hint hint).
ELF64. On other architectures only include a.out support, since we don't
know whether or not they'll have the headers necessary for ECOFF and/or
ELF, and since they only want a.out for now (execpt the mips archs, but
they do Special things). There should be a better way to select which
bits of nlist code get compiled in, but currently there is not.

- Change checkfstab so that the checkit function takes the name of the
mount point too (needed by quotacheck).
- Remove globals debug, verbose and preen
(1) split nlist() into multiple files, for clarity and to make
ELF 32/64 support easier,
(2) support multiple executable types at the same time, and
(3) add support for 32- and 64-bit ELF (32-bit ELF support
originally from OpenBSD, but with several bug fixes so
that it actually handles symbols types more correctly
(and therefore _works_ for some of the more tricky uses
of the nlist routines) and changes for 64-bit ELF support).
* Handle message retransmissions and partially sent messages correctly.
* Make sure we clear ATN after the last message is sent.
* Do the right thing if the target initiates negotiation for async mode
after having negotiated sync mode.
* Fix some cases where we set ATN with no message queued, or schedule a
message without setting ATN.
* Issue a REQUEST SENSE after an unexpected disconnect, per SCSI spec.
* Fix abort handling in a number of cases.
* Recognize selection timeouts better (to speed up probing).
ELF-outputting version of the assembler. (It was dying when it saw
some CPP line number markers.) This is temporary. (Workaround suggested
by Matt Thomas.)
would generate two interrupts, one real and one spurious. The solution
is to force a drain of the SBus->MBus write buffers after writing to the
lance to clear the interrupt. Thanks to Chris Torek for pointing out a much
easier way to do this than I had planned...
