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?)

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.

0946d128cd - Kernel call handlers cleaned up. More strict checking of input parameters.
- Moved generic_handler() from system.c to system/do_irqctl.c.
- Set privileges of system processes somewhat stricter.

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

8866b4d0ef Kernel changes:
- reinstalled priority changing, now in sched() and unready()
- reinstalled check on message buffer in sys_call()
- reinstalled check in send masks in sys_call()
- changed do_fork() to get new privilege structure for SYS_PROCs
- removed some processes from boot image---will be dynamically started later

198c976f7e System processes can be signaled; signals are transformed in SYS_EVENT message
that passes signal map along. This mechanisms is also used for nonuser signals
like SIGKMESS, SIGKSTOP, SIGKSIG.

Revised comments of many system call handlers. Renamed setpriority to nice.

42ab148155 Reorganized system call library; uses separate file per call now.
New configuration header file to include/ exclude functionality.
Extracted privileged features from struct proc and create new struct priv.
Renamed various system calls for readability.

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.

0e2a7a9730 Kernel cleanup.
Reduced kernel size by 512KB by moving private buffer into cstart() function.
Replaced assertions with erroneous return values. Removed assertions relating
to isuserp(rp), since all processes should become user processes; system
processes are now treated similar to other processes.

322ec9ef8b Moved stime, time, times POSIX calls from FS to PM. Removed child time
accounting from kernel (now in PM).  Large amount of files in this commit
is due to system time problems during development.

8d9c0886cd Created ECHO system call for testing purposes.
Furthermore, a quick way to get one's own process number.
