- remove dead code and fix warnings in pmap_zero_page/zero_page_area
- implement
pmap_clear_reference
pmap_ts_referenced
pmap_page_exists_quick
pmap_remove_all
- align pmap_qenter/qremove closer with i386 code
- fix vm_page locking in pmap_new_thread (from benno)
- add new parameter to pmap_clear_bit to return original
pte value

using the Rhine's internal shift registers which are designed
for the job. This reduces the amount of time we wait around shifting
bits, and seems to work better with some chips.
Also, provide a workaround for some newer cards which report fake PHYs
at multiple addresses. (As more cards are ID'd, I'm sure this part
of the code will have to be expanded to cover more cases.)

backout_commit.rb. Tool can be used to automate the
process of backing out either small or large commits based off of
one or more commit messages. The result of the script is a shell
script which can be edited or run as needed. New and dead files
are taken into consideration. See the program's usage statement for
more configuration details. Here's an example usage:
<programlisting>
$ mutt
[find commit message, save to disk as cvsmsg.txt]
$ backout_commit.rb ~/cvsmsg.txt
Backout directory: /usr
Backout script: backout-2003-01-31-14-04.sh
Scanning through cvsmsg.txt...done.
Change to /usr and run this script. Please look through this script and
make changes as necessary. There are commented out commands available
in the script.
Example script usage:
mv backout-2003-01-31-14-04.sh /usr
cd /usr
less backout-2003-01-31-14-04.sh
/bin/sh backout-2003-01-31-14-04.sh
rm -f backout-2003-01-31-14-04.sh
</programlisting>
checks, including the "open directory" check or a MAC check fail,
after the working directory of the process has been changed, then
the cwd of the process will be left as the target directory rather
than the original directory.
At some point, this bug might be fixable by performing the directory
change only after permission is granted for the change. In the
mean time document it (it's been there for a while).
than having change_dir() release the vnode lock on success, hold the
lock so that we can use it later when invoking MAC checks and
VOP_ACCESS() in the chroot() code. Update the comment to reflect
this calling convention. Update callers to unlock the vnode
lock. Correct a typo regarding vnode naming in the MAC case that
crept in via the previous patch applied.
cases: we might multiply vrele() a vnode when certain classes of

. Print the column headers centered (except for the left-aligned
TYPE header) using a different header for architectures where
sizeof(uintptr_t) is not four.
. Consistently do not print a '0x' prefix for hexadecimal values.
. Separate columns by a single space character.
. Pad the columns presenting an address or offset enough to hold
their respective largest value.
. Do not restrict the output to unknown file types, inodes and
sockets; allow displaying of pipes, fifos, kqueues and crypto file
descriptors too.
- Shorten an overly long line by removing a cast of printf's return
value to void.

This doesn't break anything since using sendfile(2)
is triggered later by a separate S_ISREG conditional.

- The PAM kbdint device sometimes doesn't know authentication succeeded
until you re-query it. The ssh1 kbdint code would never re-query the
device, so authentication would always fail. This patch has been
submitted to the OpenSSH developers.
- The monitor code for PAM sometimes forgot to tell the monitor that
authentication had succeeded. This caused the monitor to veto the
privsep child's decision to allow the connection.
These patches have been tested with OpenSSH clients on -STABLE, NetBSD and
Linux, and with ssh.com's ssh1 on Solaris.

under load.
This patch has been tested by Thomas and other for more than a month now,
and all (known) hangs seem to be solved.
Thomas's explanation of the patch:
* Fix the problem with the printing of the RX-error.
* Code from if_fet do better deal with the RX-recovery including a
timeout of the RX-turnoff.
* The call to vr_rxeof before vr_rxeoc have been moved to a point
where the RX-part of the chip is turned off. Otherwise there is a
window where new data could have been written to the buffer chain
before the RX-part is turned off. If this happens the chip will see
a busy rx-buffer. I have no evidence that this have occured but
god knows what the chip will do in this case!
* I have added a timeout of the TX-turnoff. I have checked and in
my 900 MHz system the flags for turnoff (both RX & TX) is seen at
the first check in the loop.
* I could see that I got the VR_ISR_DROPPED interrupt sometimes and
started to thinking about this. I then realized that no recovery is
needed for this case and therefore I only count it as an rxerror
(which was not done before).
* Finally I have changed the FIFO RX threshhold to 128 bytes. When I
did this the VR_ISR_DROPPED interrupt went away. Theory: The chip
will receive a complete frame before it tries to write it out to
memory then the RX threshold is set to store'n'forward. IF the frame
is large AND the next rx frame also is large AND the bus is busy
transfering a TX frame to the TX fifo THEN the second received
frame wont fit in the FIFO and is then dropped. By having the RX
threshold set to 128 the RX fifo is emptied faster.

Make passing the methods in a cdevsw structure optional.
Move "CANFREE" and "NOGIANT" flags into struct disk instead of the
cdevsw which may or may not be there.
Rename CANFREE to CANDELETE to match BIO_DELETE operation.
Add "OPEN" flag so drivers don't have to provide open/close methods
just to maintain such a flag.
Add temporary stopgap include of <sys/conf.h> to <sys/disk.h> until
the files which have them in the other order are fixed.
Add KASSERTS to make sure we don't get fed too many NULL pointers.
Clear our geom's softc pointer before we wither.
