wait for those cpus, instead of all of them by using a count. Oops.
Make the pointer to the mask that the primary cpu spins on volatile, so
gcc doesn't optimize out an important load. Oops again.
Activate tlb shootdown ipi synchronization now that it works. We have
all involved cpus wait until all the others are done. This may not be
necessary, it is mostly for sanity.
Make the trigger level interrupt ipi handler work.

addition, take out the checks on the $dumpdev. dumpon(8) behaves well
if given a non-existent filename. It gives a nice error message which
is better rather than the current silent failure.

$ipfilter_active. $ipfilter_enable is set to "NO" if modules fail to
load, and $ipfilter_active can be "YES" when we are not using ipf(8).

For a detailed description look at the commit log for sysctl.c
rev.1.42 -- i do not think it is appropriate to put the full
description in this manpage, and the "boot" and "loader" manpages
where this description might go are also missing a description of
a number of similar variables, so i think this it is ok to limit
documentation to this now, and update it later when I (or someone
else) have a chance to revise "boot" and "loader".
very large package is exactly the kind of thing that users buy the
CDs for, so leaving it off of a 4 CD set is very bad.
* Properly quote the last security/sudo entry.
* Add a comment in the CDROM #2 section explaining that packages don't
typically go on this disc.
The stat() and open() calls have been changed to make use of this new functionality. Using shared locks in
these cases is sufficient and can significantly reduce their latency if IO is pending to these vnodes. Also,
this reduces the number of exclusive locks that are floating around in the system, which helps reduce the
number of deadlocks that occur.
A new kernel option "LOOKUP_SHARED" has been added. It defaults to off so this patch can be turned on for
testing, and should eventually go away once it is proven to be stable. I have personally been running this
patch for over a year now, so it is believed to be fully stable.
