This patch is going to go in on the weekend unless someone has any
worthwhile nits about it. It was submitted by Hiten Pandya.
The patch basically removes random MIN/MAX implementations from
22 files in the kernel and modifies the one in sys/param.h (see the
last part of the patch) so it is present for all kernel builds.
