So this actually broke emulators/qemu because <machine/pmap.h> now
requires <sys/param.h>.  I have a patch to fix the port available at
https://reviews.freebsd.org/D36362.  What I don't know is if there are
other ports broken by this that might change how to address this?  I
would mostly hope that <machine/pmap.h> wouldn't be a header that userland
would need to use and that adding <sys/param.h> in a few places would
be the end of it.  However, if there's wider-spread breakage then I
would hack on this to avoid the need for <sys/param.h>.
