pointers to the callout handler just before and just after the callout
it invoked. I attempted to do this in a manner congruent to tracing in
Solaris's callout mechanism, but couldn't quite use the same names due
to convention and syntax differences.
Example DTrace script to generate a distribution graph of callout
execution times:
callout_execute:::callout_start
{
self->cstart = timestamp;
}
callout_execute:::callout_end
{
@length = quantize(timestamp - self->cstart);
}

Change "smaller files" to "split files" which is more in line
with what "-b" actually does.

- Mark vm.loadavg MPSAFE.
- Remove GIANT_REQUIRED from vmtotal() (everything in this routine already
has sufficient locking) and mark vm.vmtotal MPSAFE.
- Mark the vm.stats.(sys|vm).* sysctls MPSAFE.

there is nothing for it to do.

make KERNFAST=blah buildkernel
is now a short cut for
make KERNCONF=blah -DKERNFAST buildkernel
This change works for all kernel config files not named "1". I did
that to make sure that
make -DKERNFAST buildkernel
remains the same as
make -DKERNFAST KERNCONF=GENERIC buildkernel
rather than trying to build and configure "1". I've never seen a
kernel config file named "1," so I think this is a good compromise.
This should be a bit useful for users who look at the manpage and
then try to copy data CD-ROM disks using dd. A lot of us know
that bs=2048 is required, but it still manages to cause a bit of
grief to those who haven't heard about it.

have a good outcome).
