91dd9aae1a 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);
}

cff548f0dd 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.

8a7ef10b71 - 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.

910826246c 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
filesystems it is asynchronous.

645f1f4ea3 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.

b61a9dcf3f 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.

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.

d78f78230d Don't over-commit the DMA. Use the passed in size of the transfer 
rather than a fixed 512...  This fixes the mount root problem on at91.
