1a7f7d6333 at_wini: removed RO_BIT misfeature, not used any more
pm: fixed rebooting by making a copy of the monitor code from the user
    process. this is necessary because that process is dead by the time
    sys_abort() is called.

    also added more info to the "can't reply" panic.

d0cd846ae8 Added some more debug statements that are enablable by atapi_debug in the
boot monitor.

Added SCSI_SENSE command that asks the drive, with request sense, about
diagnostics for the previous error. This command is called and the results
printed when atapi_debug is enabled and atapi errors occur.

Debug output also prints actual commands sent to the drive.

Suddenly, Andy's problem has vanished. Don't know why, minor changes
(e.g. moving the atapi packet data from stack to static) shouldn't have
fixed this.. But with the debug info, we stand a better chance of
finding out what it was if it occurs again.

647e179038 . release fixes
. added OPENCT ioctl to at driver, which returns the number of times
  a device is opened. if it's not opened exactly once, new partition info
  will not be read in (at the next open after this close). included
  this check in autopart.

b993f51980 at bugfix - openct only increased on opens when 0, openct always decreased
on closes..

this causes partition tables not to be re-read sometimes..

this causes mayhem..

f902df5c5a Give AT driver 8k stack instead of 1k.. probably not necessary, but 1k
is a little meager, so let's be on the safe side

1d3fb6ea2e ata_std_timeout boot monitor variable to override short timeouts on

f3500010b7 Moved open-ATAPI-as-RW check to before open-first-time check.. otherwise
you can open an ATAPI device as RW if it's already opened for read.

74711a3b14 Check if kernel calls is allowed (from process' call mask) added. Not yet
enforced. If a call is denied, this will be kprinted. Please report any such
errors, so that I can adjust the mask before returning errors instead of
warnings.

Wrote CMOS driver. All CMOS code from FS has been removed. Currently the
driver only supports get time calls. Set time is left out as an exercise
for the book readers ... startup scripts were updated because the CMOS driver
is needed early on. (IS got same treatment.) Don't forget to run MAKEDEV cmos
in /dev/, otherwise the driver cannot be loaded.

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.

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

435dd377ed Added an IDENTIFIED flag that is set on successfully identified drives.
This avoids the bug scenario where DEAF but not-w_identify()d drives are
never properly identified, but are seen as real devices.

a63d324caa Small update to shared driver code: SYS_EVENT (signal) is now known.

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.

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.

0165662cd9 Replaced flagalrm() timers with another technique to check for timeouts.
This allowed removing the p_flagarlm timer from the kernel's process table.
Furthermore, I merged p_syncalrm and p_signalrm into p_alarm_timer to save
even more space. Note that processes can no longer have both a signal and
synchronous alarm timer outstanding as of now.

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.
