Remove the unnecessary inclusion of disklabel.h in cd9660_vfsops.c so
that I don't have to worry about the latter when changing disklabel.h.
Supply prototypes for some functions that were implicitly declared and
fix the resulting warnings and errors (timevals were punned to timespecs).
Removed inb function since it's more correctly in pio.h
Copied write_eflags and read_eflags over from npx.c
(Some changes to the macros suggested by Bruce were not made at this
time since his suggestions probably apply to all the macros and
these inlined/macro definitions need a lot of cleaning up at some

Fix from Bruce Evans. There were missing sets of parantheses:
1. The checks for the standard data selectors were botched, so %ss == 0
and probably %cs == 0 were allowed. A fix is enclosed. The checks
for the standard selectors could be omitted without losing anything
since the standard selectors pass the valid_ldt_sel() tests.

you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support. This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.
To get this functionality, you must define DSI_SOFT_MODEM.
The program to actually employ the ioctl is not included, but the entire
source looks like this:
#include <sys/ioctl.h>
#include <stdio.h>
main()
{
unsigned char buffer[100000];
int i;
read(0,buffer,100000);
if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
perror("ioctl");
return i;
}
And you use it like this:
smload < data144b.dsi > /dev/ttyid3
You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

This puppy is in good shape now.
It is a fully blown SCSI-driver, but it isn't a high performance one. It is
implemented entirely with polled I/O, and is intended to drive CD-ROM's, not
disks and tapes. It will run disks and tapes if asked to, but it isn't a
very good idea to do so. Transfer-rates max out at 600-700 kbyte/sec.
There is one problem: when write-requests get over 8192 bytes, the pseudo-DMA
stalls. This is only a problem if you dd(1) to a raw-device of some kind,
for mounting a disk it is ok. I have circumvented this by disabling the
pseudo-DMA in those cases.
It's very unlikely that I will spend more time on improving the performance
of this driver, it can do what I want it to now: install from a CD-ROM, and I
don't see any benefit in actually adding interrupts to the driver, considering
that performance never will be better than 700 kbyte/sec anyway.
You can install it under 1.1.5 too, by adding the lines to files.i386, your
config-file and copying pas.c and ic/ncr_5380.h over.
I will fix any bugs I can get a handle on.

to something more recent than the ancient 1.2 release contained in
4.4. This code has the following advantages as compared to
previous versions (culled from the README file for the SunOS release):
- True multicast delivery
- Configurable rate-limiting of forwarded multicast traffic on each
physical interface or tunnel, using a token-bucket limiter.
- Simplistic classification of packets for prioritized dropping.
- Administrative scoping of multicast address ranges.
- Faster detection of hosts leaving groups.
- Support for multicast traceroute (code not yet available).
- Support for RSVP, the Resource Reservation Protocol.
What still needs to be done:
- The multicast forwarder needs testing.
- The multicast routing daemon needs to be ported.
- Network interface drivers need to have the `#ifdef MULTICAST' goop ripped
out of them.
- The IGMP code should probably be bogon-tested.
Some notes about the porting process:
In some cases, the Berkeley people decided to incorporate functionality from
later releases of the multicast code, but then had to do things differently.
As a result, if you look at Deering's patches, and then look at
our code, it is not always obvious whether the patch even applies. Let
the reader beware.
I ran ip_mroute.c through several passes of `unifdef' to get rid of
useless grot, and to permanently enable the RSVP support, which we will
include as standard.

opened with this flag set, the printer is
not primed, and no check is made to see that
the printer is online. This can only be used

All routines now detects media change correctly.
DELAY_GETREPLAY increased for long time access from first track

mcd_waitrdy() now use MIN_DELAY=15 as minimal delay which independs

mcd_doread() now uses real status (old code uses obsoleted soft copy of it).

mcd_statrt(): add missing splx(s), cause dead hang with unmatched slpbio()
optimize mcd_doread(), don't set CD mode each time, keep soft copy of mode.
call getdisklabel() _after_ mcdsize() for proper sizes
mcdopen(): old code forget to set MCDREADRAW in flags when open RAW
partition, doread check it for setting RAW CD mode.

Remove stale dependencies for the above now-normal objects and for

generate lists of assembler source files so the lists to be mkdep'ed

so the dependencies for gnu/fpemul/*.s are incomplete. *.S files

Moving around the dependencies exposed a bug in make. It doesn't
