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?)

52965b6f17 Various updates to support dynamically starting drivers.
Output during initialization should be suppressed. Unless an error occurs.
Note that main() can now be main(int argc, char **argv) and arguments can
be passed when bringing up the driver.

d62e515660 Small update to SYS_IRQCTL -> setting an interrupt policy now allows the caller
to provide an index (0 .. 31) that is passed in the HARD_INT message when an
interrupt occurs. The NOTIFY_ARG field contains a bitmap with all indexes for
which an interrupt occured.

fe0dcb5c00 AT driver is not modified (debugging only);
TTY: select and revive with new notify and FS call back;
kernel: removed old notify code; removed ugly prepare_shutdown timer
kputc: don't send to FS if PRINTF_PROC fails

a63d324caa Small update to shared driver code: SYS_EVENT (signal) is now known.
Fixed drivers. HARD_STOP message no longer exists.

8c024e28a1 Changed Makefiles: drivers are now installed in /usr/sbin.
TTY now gets SYS_EVENT message with sigset (e.g., SIGKMESS, SIGKSTOP).

ec24a0798c Updated function key mapping because of possible changes to NOTIFY.
The TTY driver now only notifies the IS server about function key event,
but does not tell which keys are pressed. The IS servers queries the TTY
driver to find out about this.

c2cd510adf Removed debug dumps from the PM and FS servers. The dumps are now done by the
IS servers, which obtains a copy of the data through the getsysinfo() system
call. CTRL-F1 now is a special TTY key to shows function key mappings.

c281867f46 Fixed bug relating to FS and MEMORY during startup;

f2a85e58d9 Various updates.
* Removed some variants of the SYS_GETINFO calls from the kernel;
  replaced them with new PM and utils libary functionality. Fixed
  bugs in utils library that used old get_kenv() variant.
* Implemented a buffer in the kernel to gather random data.
  Memory driver periodically checks this for /dev/random.
  A better random algorithm can now be implemented in the driver.
  Removed SYS_RANDOM; the SYS_GETINFO call is used instead.
* Remove SYS_KMALLOC from the kernel. Memory allocation can now
  be done at the process manager with new 'other' library functions.

6d23f072f3 Cleaned up src/lib/utils library. Renamed server_ functions to more logical
names. All system processes can now either use panic() or report() from
libutils, or redefine their own function. Assertions are done via the standard
<assert.h> functionality.

5a43b84e2d Fix for 'the kermit problem' (keyrepeats happening before the keyrepeat
timeout). A fix is to treat the alarm and interrupt cases differently and
only call the interrupt handler when an actual interrupt has been seen. No
apparent adverse effects.

0165662cd9 Replaced flagalrm() timers with another technique to check for timeouts.
This allowed removing the p_flagarlm timer from the kernel's process table.
Furthermore, I merged p_syncalrm and p_signalrm into p_alarm_timer to save
even more space. Note that processes can no longer have both a signal and
synchronous alarm timer outstanding as of now.

cd72f80639 Disabled clearing screen in tty driver, started console printing after an
initial 1-line scroll at last line. If clearing screen in trailer of boot
monitor is disabled, all previous boot monitor and console messages are
preserved on rebooting.

All that's needed now is a scrollback buffer to see all old messages..
(Even from the boot monitor, bios, previous boots...)

c2be104821 Improved NOTIFY system: fixed a minor error, ignore pending notifications
on SENDREC system calls. To be done: resource (buffer pool) management;
make it structurally impossible to run out of buffers.

77c3213948 Optimized scheduling code. Old code is still available withing DEAD_CODE
and NEW_SCHED_Q definitions. Some minor problems are being traced at the
moment. This commit is meant to backup my files.
