Document parts of the case statements, which instruction is emulated.
Marked all dubious parts with ATS :-) for better searching. First round
of better documentation of the math emulator and of bugfixing it.

It would be much more convenient if "make world" didn't clobber my
UUCP configuration files in /etc/uucp. Perhaps the easiest fix would
be to change the names of the sample configuration files:

Description:
When calling remote uucp site dialing succeeds, but standard
login chat fails. Debug file shows that uucico does not see
any characters send from remote.
Repeat-By:
use sio drivers, 16450 base serial and standard taylor configuration
provided with the GAMMA release. Run uucico and observer.
Fix:
define HAVE_BSD_TTY instead of HAVE_POSIX_TTY in common_source/policy.h
and recompile.
Define new option, INACCURATE_MICROTIME_IS_OK. When this is defined,
the NTP kernel PLL is disabled, and acquire_timer0() is enabled, thus
opening the door for microtime() (and hence gettimeofday()) to return
bogus timestamps. This option is necessary for the `pca' driver to
work, but is implemented to underscore the fact that accurate timekeeping
and the `pca' driver are incompatible at present. If someone writes a version
of microtime() that works when the `pca' driver is being used, this can get
junked.
Tell the user that we didn't try to set the bus speed, in case they're
used to NetBSD or older versions of the code that did do it.
Will document TUNE_1542 also.
Enable kernelized NTP PLL support on the daemon side.
If your clocks suddenly start running backwards 500 hours per day,
let me know.
ifdef out some bogus declarations.

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.

As a result of the distribution crontab, /usr/libexec/atrun was being run
only once an hour instead of every five minutes. This was due to a minute
specification of 0/5 -- which should have been */5. This has been fixed.
Expect your /var/cron/log to grow much faster now.

Changes from John Dyson and myself:
1) Removed all instances of disable_intr()/enable_intr() and changed
them back to splimp/splx. The previous method was done to improve
the performance, but Bruces recent changes to inline spl* have
made this unnecessary.
2) Cleaned up vm_machdep.c considerably. Probably fixed a few bugs, too.
3) Added a new mechanism for collecting page statistics - now done by
a new system process "pagescan". Previously this was done by the
pageout daemon, but this proved to be impractical.
4) Improved the page usage statistics gathering mechanism - performance is
much improved in small memory machines.
5) Modified mbuf.h to enable the support for an external free routine when
using mbuf clusters. Added appropriate glue in various places to
allow this to work.
6) Adapted a suggested change to the NFS code from Yuval Yurom to take
advantage of #5.
7) Added fault/swap statistics support.

Change the private declarations from dlopen,dlclose,dlsym,dlctl
to public. These functions are also used in /usr/include/link.h,
so it looks, like they shouldn't be private.
I will ask Paul about that, if this is correct.
/dev/null was not a very good choice of shell for login-disabled users.
Used the canonical non-existent file (/nonexistent) instead This should
probably be documented somewhere, but it's unclear where the right
place is (passwd(5)? login(8)? hier(7)? all three?).

Fixed brokeness in the support of the 83C790/Elite Ultra (now that I
finally have the f**king documentation!):
1) Changed all the numeric register offsets to symbolic ones (it should
have been this way originally).
2) If 16 bit, disable the shared memory when not using it. Apparantly
switching between 8/16bit mode makes the Ultra unhappy unless
this is done (i.e. it trashes the bus).
Modify wdprobe() to correctly recognise some 2 drive systems,
on which it was failing. Modifications follow ATA, but also
allow some weird setups which seem to contradict ATA (aaarrrrgghhh!!)

from kimmel@varese.cs.umass.edu (Matt Kimmel):
"el" driver for 3COM 3C501. This driver has some serious performance
problems and drops packets on the floor like hot potatos.
Change default permission of /var/mail to 01777, because
MUA must have s-bit in other case (security hole).
This fix needed for procmail too, because procmail
uses NFS-locks in /var/mail directory
Changes to lpt driver:
- ansi prototypes in lpt.c
- a bit of tidying in lpt.c
- ioctl in lpt.c for switching between polling and using interrupts
- added lpt.h - needed for ioctl to allow switching between polling
and interrupt-driven modes.

First pass at adding locale support. This code only deals with the LC_CTYPE
class of locale data, but could be extended to handle other locale
classes, as well as message catalogues and other non-locale i18n
support.
I have left the old _ctype_ array in place, and moved the ctype.h
header to octype.h, so that existing shared binaries will still be
able to find and use it as they require.
See /usr/src/share/locale for information on how to create new locale
data files (eventually this procedure will be improved). I'd like to
have a family of locale files for various countries, languages, and
character sets, so please contribute some.
This code was originally written by Paul Borman and contributed to
4.4; I did the integration, and have somewhat tested it. crt0.c
probably ought to call setlocale() if it doesn't already, but I'd like
for people to create some locale files and try things manually first
before I make every program do this.
Upgraded to Delaware version 3.3p (yes, that's right, they're not increasing).
This version still doesn't talk to the kernel PLL code, but you should be
able to convince it to do so relatively easily. Also deleted some junk
files and fixed all compilation warnings.
