To use this: recompile src/gnu/usr.bin/cc, compile your kernel. The
files you want to profile should be compiled with '-a -g'. "strip -x"
the kernel and run. You don't need to profile all files in the kernel.
My next commit is the program to extract the data from the running kernel.

the only vnodes getting released these days are directories and things which
gets forced out of the VM/cache. The latter is not numerous enough to keep
the pool of vnodes needed for the namecache sufficiently big.
2. Purge invalid entries in the namecache as soon as we notice them. This
avoids a stale entry pushing out a valid entry on the LRU list.
3. Speed up the lookup in the namecache by avoid a special case branch.
4. Make the cache purge routines do the thing they're supposed to, and in
a decently efficient manner.
5. Make the size of the namecache follow the number of vnodes, so that we
can always point to all the vnodes we have in core.
6. Readability has gone way up.
7. Added a "options NCH_STATISTICS" feature that will gather more
detailed statistics on the performance of the namecache.

object has fallen off the end of the cached list - this is likely the
last reference to the vnode and it should be reused before non file
vnodes that are already on the free list (VDIR mostly).
Fix it so that calls to extend_get won't dereference 0 when "swap
on sd.." calls sdsize() on systems with no SCSI devices.
This probably really fixes Poul's "boot with no SCSI" problem.

o local.h: reverse option logic from EXCLUDE_* to AUDIO_*
o pas2_mixer.c: small addition
o ad1848.c: minor change with macro names
o sequencer.c: minor change with note check
o many spelling corrections in comments in about every other file

Feb. 10th snapshot. The keyboard probe in the bootblock seems to
have been singled out as the cause of these problems, so I've beefed it
up alittle. This pushes us right up to the edge of the size limit:
the second stage boot is now 7152 bytes in size, just 8 bytes under
the wire. On the other hand, the new probe now does almost exactly
what syscons does, so hopefully this will do the trick. It seems
to work properly on my hardware, but then so did the old probe.

Be carefull about over usage of volatile, it really killed performance
in a few areas and there was a better place to make things volatile in
almost all cases. The driver can now receive at full speed without RNR
