is ultimately silly because no locks are held in user space while traversing
the list via kvm_reads... really, this should use the sysctl interface
which *is* protected by a lock in the kernel.
the magicness of 200. Cleaned up the remaining parts. Circularisation
of the list of malloc types was a kernel bug (now fixed). Interfering
with applications' definitions of pgtok is a system header bug (not
fixed).
changed from a simple list to a circular one. We compensate by only
looping until we see the first address again. Before, things would
terminate because it was limited to 200 iterations. This lead to
bogus statistics and repeating stats for memory types.
This should be merged into 3.2, as the same bug is there.
I'm not sure why we have `mvstat -z'. `sysctl vm.zone' gives more
information. OTOH, `sysctl vm.zone' shouldn't return ASCII data,
and reporting of memory use should be integrated, at least as an
option.
the display wrapped around.
This decreases the default maximum number of disks shown to 2, so things
don't wrap around so easily. Also, it fixes the header display issues.

peripheral drivers can determine where in the devstat(9) list they are
inserted.
This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and
any ports that depend on the devstat code, since the size of the devstat
structure has changed. The devstat version number has been incremented as
well to reflect the change.
This sorts devices in the devstat list in "more interesting" to "less
interesting" order. So, for instance, da devices are now more important
than floppy drives, and so will appear before floppy drives in the default
output from systat, iostat, vmstat, etc.
The order of devices is, for now, kept in a central table in devicestat.h.
If individual drivers were able to make a meaningful decision on what
priority they should be at attach time, we could consider splitting the
priority information out into the various drivers. For now, though, they
have no way of knowing that, so it's easier to put them in an easy to find
table.
Also, move the checkversion() call in vmstat(8) to a more logical place.
Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and
for putting up with the long time it has taken me to commit it. Bruce did
object somewhat to the central priority table (he would rather the
priorities be distributed in each driver), so his objection is duly noted
here.

generation was causing unaligned access faults on the Alpha.
I have incremented the devstat version number, since this is an interface
change. You'll need to recompile libdevstat, systat, iostat, vmstat and
rpc.rstatd along with your kernel.
