/*
 * mkfspm device
 *	Get the size of the Priam disk "device" and make a root
 *	filesystem in partition 0.  This makes a filesystem using the
 *	entire disk except for the boot and swap areas.
 *
 *	The raw device is specified, but both the block and character
 *	devices are expected to be available (created).  The filesystem
 *	is made on /dev/pm?a where /dev/rpm?a is the argument.
