and instead add platform, firmware and EFI stubs to the loader.
The net effect of this change is that besides a special console and
disk driver, the kernel has no knowledge of the simulator. This has
the following advantages:
o Simulator support is much harder to break,
o It's easier to make use of more feature complete simulators.
This would only need a change in the simulator specific loader,
o Running SMP kernels within the simulator. Note that ski at this
time does not simulate IPIs, so there's no way to start APs.
The platform, firmware and EFI stubs describe the following hardware:
o 4 CPU Itanium,
o 128 MB RAM within the 4GB address space,
o 64 MB RAM above the 4GB address space.
NOTE: The stubs in the skiloader describe a machine that should in
parts be defined by the simulator. Things like processor interrupt
block and AP wakeup vector cannot be choosen at random because they
require interpretation by the simulator. Currently the simulator is
ignorant of this.
This change introduces an unofficial SSC call SSC_SAL_SET_VECTORS
which is ignored by the simulator.
Tested with: ski (version 0.943 for linux)
long time. Go ahead and commit the patch since a co-worker has been
working up a code patch in this area and wondered why it hasn't been
committed yet.

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
Approved by: benno
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>
