e3697d4040 Mark kern.ttys as MPSAFE. 
sysctl now allows Giantless calls, so make kern.ttys use this. If it
needs Giant, it locks the proper TTY anyway.

aaaff3620b Add explicit static DTrace tracing to the callout mechanism, capturing 
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);
}

855f844ab0 When "-b" is specified, one could easily create "smaller" files 
that are much larger than expected (given the default size).
Change "smaller files" to "split files" which is more in line
with what "-b" actually does.

a9601871c9 - Mark all standalone INT/LONG/QUAD sysctl's MPSAFE. This is done 
inside the SYSCTL() macros and thus does not need to be done for
  all of the nodes scattered across the source tree.
- Mark the name-cache related sysctl's (including debug.hashstat.*) MPSAFE.
- 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.

d7c8a44c0d Tweak the wording for vfs_mark_atime() since the I/O it is avoiding by not 
updating va_atime via VOP_SETATTR() isn't always synchronous.  For some

4efa7c83e1 Push down Giant in the vlnru kproc main loop so that it is only acquired 
around calls to vlrureclaim() on non-MPSAFE filesystems.  Specifically,
vnlru no longer needs Giant for the common case of waking up and deciding
there is nothing for it to do.

71d7b5671d Implement an idea from Sam Leffler: 
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.

that bs=2048 is required, but it still manages to cause a bit of
grief to those who haven't heard about it.
