86e3333454 New error codes for IPC errors. 
Made VM code debug output disappear.

2bf8bfe126 Turn IPC warning messages off by default 
(because inet deadlocks are normal and will confuse our users).

ea75918df1 printf() by kernel and servers now send messages to an array of processes, 
OUTPUT_PROCS_ARRAY in <minix/config.h>, in that order, terminated by NONE.
log no longer forwards messages to tty itself. This leads to less funny
loops and more robust debug-message handling. Also the list of
processes receiving messages can easily be changed around or disabled by
editing the array (e.g. disable it by changing the array to { NONE }.).

c655d8b3ae Added shutdown_started global variable. If it's set, we're in the 
process of doing a shutdown.

Initial purpose is - suppress dead process diagnostic message.

b4d7de6ee1 New makefile (src/tools/Makefile) logic: 
- make fresh install: still builds new everything (libraries, services, image)
- make clean image: only builds new boot image (about 5 sec. now!)

872687ddfc Scheduling updates to the kernel. Sched() function now is single point for 
policy. Actual policy not yet implemented.

PM calculates nice values for processes in boot image.

IS debug dumps improved (Shift+F1-F4).

a01645b788 New scheduling code in kernel. Work in progress.

bfb7608412 various small fixes. 
. motd update (ast)
 . made /usr/local/man/man* and made them bin-owned (mtree)
   (to let bin install there)
 . made copyright notice in kernel 1987-2006 (ast)
 . added chown -R bin /usr/src so that bin can compile everything

b293e689a9 . Allow drivers to to physcopy() (table.c) 
. Also allow receive() to be done from kernel processes, not just
  sendrec(). This is because receive()s can't harm the kernel processes,
  but are done from the CLOCK task (without sendrec()).

74711a3b14 Check if kernel calls is allowed (from process' call mask) added. Not yet 
enforced. If a call is denied, this will be kprinted. Please report any such
errors, so that I can adjust the mask before returning errors instead of
warnings.

Wrote CMOS driver. All CMOS code from FS has been removed. Currently the
driver only supports get time calls. Set time is left out as an exercise
for the book readers ... startup scripts were updated because the CMOS driver
is needed early on. (IS got same treatment.) Don't forget to run MAKEDEV cmos
in /dev/, otherwise the driver cannot be loaded.

e561081545 Miscellaneous clean ups and fixes to the kernel. 
Support for FLOPPY in boot image. (Set controller=fd at boot monitor.)
Moved major device numbers to <minix/dmap.h> (maybe rename to dev.h?)

89cf745fe2 Single boot driver loaded, while multiple can be included in the boot image. 
The user needs to set label=... to choose the driver of his or her choice.
This driver will be mapped onto the controller that is set in controller=...

Minor cleanup of kernel source code (boot image table now is static).

b69ca94efb Fixed 'bug' in log driver that caused kernel messages not to be displayed. 
This was caused by a change in the shared driver code. Not log's fault.

Renamed #definitions of driver process numbers, e.g., TTY now is TTY_PROC_NR.
All known (special) processes now have consistent naming scheme. Kernel tasks
don't follow this scheme.
