Jorrit Herder e0a98a4d65 * Fixed bug relating to nested locking in interrupt handlers. The nested lock
caused interrupts to be reenabled (due to unlock), which caused a race. The
problems were especially visible on slower machines.
* Relocated free memory parsing to process manager. This saved quite some
code at the kernel level. Text size was reduced by about 650 bytes.
* Removed locks for updating the realtime in the clock's main loop and the
get_uptime function. Interrupts are no longer reentrant, so realtime is
immediately updated.

Jorrit Herder 0899f82ab2 Fixed some minor issues with the NOTIFY call. 2005-05-24 14:35:58 +00:00
Jorrit Herder ccd17ecfed New NOTIFY system call! Queued at kernel. Duplicate messages (with same source
and type) are overwritten with newer flags/ arguments. The interface from
within the kernel is lock_notify(). User processes can make a system call with
notify(). NOTIFY fully replaces the old notification mechanism.
