1d8aed840c . no more HZ, but use sys_hz() to get that value 
. memory maps in physical memory (for /dev/mem) with new vm interface
 . pci complete_bars() seems to be buggy behaviour sometimes
 . startup script opens its own stdout, stderr and stdin so init doesn't
   have to do it

c078ec0331 Basic VM and other minor improvements. 
Not complete, probably not fully debugged or optimized.

8ea438ae93 Retired DEV_{READ,WRITE,GATHER,SCATTER,IOCTL} (safe versions *_S are to 
be used and drivers should never receieve these 'unsafe' variants
any more).

b01aff70d2 use servers/inet/mq.[ch] to queue messages using mq_queue() in 
libdriver.  at_wini now queues messages it can't handle it receives when
waiting for an interrupt. this way it can do receive(ANY) and timeouts
should be working again (were broken for VFS, as with the advent of VFS,
at_wini could get requests from a filesystem while it was waiting for an
interrupt - as a hack, the receive() was changed to receive(HARDWARE)).

Added mq.c to libdriver, and made libdriver an actual library that
drivers link with -L../libdriver -ldriver. (So adding files, if
necessary, is easier next time.)

e929676268 . made libdriver understand *_S variants 
. ioctl, transfer and 'other' functions get an extra parameter: 'safe', int
  is nonzero if function is called with *_S variant ('other' if ioctl)

f877da3aec endpoint migration for drivers. 
mostly renaming message field names to the new names.

tty stored process numbers in chars in tty and pty structs - now ints.

87dbfc7dda Added DEV_PING message type to drivers (but not ethernet drivers) so 
RS can monitor them.

7de7ca978d Security check on physical address to be < 16 MB (ISA DMA uses 24-bit 
addressing, which can address 16 MB max).
Floppy driver now dynamically loaded.

52965b6f17 Various updates to support dynamically starting drivers. 
Output during initialization should be suppressed. Unless an error occurs.
Note that main() can now be main(int argc, char **argv) and arguments can
be passed when bringing up the driver.

a63d324caa Small update to shared driver code: SYS_EVENT (signal) is now known. 
Fixed drivers. HARD_STOP message no longer exists.

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.

c389801a5f Made timeout and no. of errors in at_wini dynamically settable 
by ioctl; made catch-all function in driver table also called when
unrecognized ioctl called, so drivers can add their own ioctl codes.

640eb73ca2 New log driver; buffers messages and makes them available to userland. 
Added some fields in the generic device table to support this driver
using libdriver. Updated other drivers to fill these fields with nops
and NULLs.

c281867f46 Fixed bug relating to FS and MEMORY during startup; 
Relocated some syslib functions to utils library;
Changed location of 'Multiuser startup ..." echo in /etc/rc

6d23f072f3 Cleaned up src/lib/utils library. Renamed server_ functions to more logical 
names. All system processes can now either use panic() or report() from
libutils, or redefine their own function. Assertions are done via the standard
<assert.h> functionality.
