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.

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.

ca80161f40 . Junk-filling gap+stack code on exec() if enabled (not enabled now)

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)

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.

f2e16763e7 Removed PM signon for INET. Now daemonized in /usr/etc/rc. 
SIGTRAP generated in PM (where it belongs / no longer in kernel).
Updated Makefiles: servers are now installed in /usr/sbin.

eba45510a9 New alarm(2) timers mechanism. 
Kernel no longer keeps track of user alarms on behalf of the PM.
Instead, the PM maintains its own list of watchdog timers, and
uses one synchronous alarm (at the kernel) to get notifications
for expired user timers.

42050e39f8 kernel and servers send diagnostic messages to IS; IS sends them to TTY 
and the new log driver if enabled.

new usyslogd is started from /usr/etc/rc. New device created by
MAKEDEV.sh. /var/log created by etc/mtree/minix.tree (on root for
now). Made select() slightly more generic, with less code duplication.

904cf1f84d A "fix" for bug no. 2 is to check if the process slot has disappeared. 
Not a really good solution (as it might not catch situations in which this
is caused by another bug), but the forrest of checks necessary might be worse
than this quick fix - because when looking for the cause, I found some other
cases in which the PM would panic as well. See info in bug 2 for details.

Another fix is to delay notification of PM by SYSTASK of signals delivered
internally until after the reply (e.g. of exec()), because the reply would
be messed up otherwise (receiving the notify instead of reply). This caused
SIGTRAP not to be delivered properly with traced processes.
