Calculation of 'cd->cmdscount' now as in 'sd.c' (required for ncr scsi).
CDOUTSTANDING defined as '1' (as the comment says), was '2' in fact ...
Debugger takes an (char*) argument, changed macro definition accordingly.

a9a9ceeae2 Rather than exclude bounce buffers support with NOBOUNCE, include it
with BOUNCE_BUFFERS. This is more intuitive, and is better for future
multiplatform support. Added BOUNCE_BUFFERS option to the GENERIC and
LINT kernel config files.

4d4250da00 1) Changed ddb into a option rather than a pseudo-device (use options DDB
in your kernel config now).
2) Added ps ddb function from 1.1.5. Cleaned it up a bit and moved into its
   own file.
3) Added \r handing in db_printf.
4) Added missing memory usage stats to statclock().
5) Added dummy function to pseudo_set so it will be emitted if there
   are no other pseudo declarations.

c97639b923 1) cleaned up after Garrett - fixed more redundant declarations, changed
use of timeout_t -> timeout_func_t in aha1542 and aha1742 drivers.
2) fix a bug in the portalfs that was uncovered by better prototyping -
   specifically, the time must be converted from timeval to timespec
   before storing in va_atime.
3) fixed/added some miscellaneous prototypes

07e1c7f69d Change all #includes to follow the current Berkeley style. Some of these
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.

This also includes support for second-directory compiles.  This is not
quite complete yet, as `config' doesn't yet do the right thing.  You can
still make it work trivially, however, by doing the following:

rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend

239ae571f1 Bug fixes and performance improvements from John Dyson and myself:
1) check va before clearing the page clean flag. Not doing so was
	causing the vnode pager error 5 messages when paging from
	NFS. (pmap.c)
2) put back interrupt protection in idle_loop. Bruce didn't think
	it was necessary, John insists that it is (and I agree). (swtch.s)
3) various improvements to the clustering code (vm_machdep.c). It's
	now enabled/used by default.
4) bad disk blocks are now handled properly when doing clustered IOs.
	(wd.c, vm_machdep.c)
5) bogus bad block handling fixed in wd.c.
6) algorithm improvements to the pageout/pagescan daemons. It's amazing
	how well 4MB machines work now.

71b67e5a56 Make everything compile with -Wtraditional. Make it easier to distribute
a binary link-kit.  Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.

NB: -Wtraditional will henceforth be forgotten.  This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax.  These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.

1d18814c41 Patch from Julian Elischer:
Here is the fix for the 'hanging' bug.

This bug happenned whenever two operations were already underway on the
disk and a third (non-IO) command was requested..
in this case the process submitting the NON-IO command was requested to wait,
and a flag set so that on completion of the IO commands, the Non-io command
was given priority over any pending IO commands. (the queue is not
allowed to drain while there are pending "special" ops).

The flag that indicated this was not being reset, so further IO commands
were prohibited from that moment on.

Subject: Re: Error reading from DAT (fwd)
Date: Mon, 11 Oct 1993 03:02:39 -40962758 (WST)

Some tapes won't do anything until you tell them to load.
Other tapes think that being asked to load is a great excuse to
make the next command return a "unit attention" (media changed) error.
Since we need to do the load, throw in a dummy instruction to cop the
error.

specifically for DEC DAT drives.

1/ fix bug where cd0a was unusable because it was compared against
the number of 2k blocks not the number of 512byte blocks.. gave
an error for all reads past 1/4 way through the disk (cd0d was ok).

2/ fix open code so that it now notices if a disk has been changed
and updates the disklabel.

3/ use the new error handling code from st.c

4/ start adding stuff to get ready for using cd_scsi_cmd from
cd_start (like is done in st and sd)

5/ more general cleanups including making dmesg report
sector size of disk.. (believe it or not SUN drives use 512 byte)

9c6b6f0846 The scsi cd.c driver is now fully dynamic. You can change the lines
in your config file from:
device          cd0
device          cd1
...
device          cdn
to either
device          cd0
or
psuedo-device   cd0

The driver now dynamically allocates all per unit dependent structs, so it
will never run out of units (okay, so now we need 32 bit device major/minor
numbers!).  It will allocate unit numbers as it needs them.
