I'm not convinced there is anything major wrong with the patch but
them's the rules..
I am using my "David's mentor" hat to revert this as he's
offline for a while.
- 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
failures occur. This appears to stem from earlier Giant/file
descriptor lock pushdown and restructuring.

. 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.

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