647e179038 . release fixes 
. added OPENCT ioctl to at driver, which returns the number of times
  a device is opened. if it's not opened exactly once, new partition info
  will not be read in (at the next open after this close). included
  this check in autopart.

94ed5c2a4c Separated one-time keyboard initialization from per-console keyboard 
initialization. One-time init is called from tty.

Side effect is that the one-time init is done after the sys_getmachine()
call, which makes set_leds() work, which makes numlock go off at booting.

c392c177b5 Boot environment option 'bios_remap_first'. Thios option remaps the first

b993f51980 at bugfix - openct only increased on opens when 0, openct always decreased 
on closes..

this causes partition tables not to be re-read sometimes..

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.

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.

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.

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.

ccd17ecfed New NOTIFY system call! Queued at kernel. Duplicate messages (with same source
