b5e3e6d18c Two 'dynamic driver' features in FS:
.  When drivers disappear that have pending select()s, wake up
   those user processes with EAGAIN so that they can retry their
   select() and won't hang forever on it.
.  When drivers re-appear and are mapped into the dmap, run through
   the list of mounted filesystems and re-dev_open() every one (for
   partition tables and such). This can't happen before the driver
   has exec()ced itself, so processes that have fork()ed but not
   exec()ced yet are marked as DMAP_BABY in the dmap table if they
   are dmapped before they are execced. If that happens, the above
   procedure happens after the exec(). If the exec() happens before
   the dmapping, it (the dev_open()ing) happens right away.

86ed54ee94 FS:
. unmap device drivers from dmap when PM signals they are dead
	. new null-io function (no_dev_io) to fill in for io functions
	  of unmapped drivers
	. driver (process number) of unmapped drivers is NONE instead of
	  0 (a valid process number)

IS:
	. print mutable flag of dmap table too

FS changes require sync() to be done 'manually' (currently by
reboot/shutdown) at shutdown time; could be caught by SIGTERM in
the future.

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.

Support for FLOPPY in boot image. (Set controller=fd at boot monitor.)

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.

6e8f484b3b . added cd-probe logic; tries to find the right root filesystem
if the boot monitor parameter is set. it also sets a boot monitor
  parameter (by talking to the PM) so userland knows it.
. ramdisk copy code made slightly smarter
. various select() prettifications (work in progress)

f1153541c7 Fixed bug in PM that caused update program not to be scheduled, so that
sync was not periodically run. Chain of timers was accidentially broken.

Kernel sends SIGKSTOP signal on shutdown. FS calls sync to clean up.

42050e39f8 kernel and servers send diagnostic messages to IS; IS sends them to TTY
and the new log driver if enabled.

new usyslogd is started from /usr/etc/rc. New device created by
MAKEDEV.sh. /var/log created by etc/mtree/minix.tree (on root for
now). Made select() slightly more generic, with less code duplication.
