ca80161f40 . Junk-filling gap+stack code on exec() if enabled (not enabled now) 
. Allow 'boot monitor' variable changes and additions by svrctl call

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)

f0594a9e6d - Fixed comments in various system call handlers. Work in progress on new 
sys_privctl() call to dynamically start servers and drivers.

- Shutdown sequence slightly adjusted: called as watchdog timer to let the
  busy sys_abort() call from the PM return first.

- Changed umap_bios() to have more restrictive check: BIOS memory is now
  allowed in BIOS_MEM_BEGIN to END (interrupt vectors) and BASE_MEM_TOP
  to UPPER_MEM_END. Hopefully this keeps QEMU and Bochs happy.

8d3e390bda Added new BASE_MEM_TOP to restrict sys_vircopy() calls from BIOS. 
Updated comments at PRINTF_PROC --- it works again.

09830fc33e Allowed printing diagnostic messages (either from system processes or the 
kernel) to the log driver. The log driver forwards such output to the TTY.

Changed driver_task() not to send a reply if the return value is EDONTREPLY.

d2d975246d Kernel sends SIGKSTOP just before shutdown. Drivers do clean up and exit. 2005-07-20 15:28:05 +00:00

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.

- katoi, kstrncmp replaced by normal library procedure again;
- rm_irq_handler() interface changed (simply pass hook pointer);
