	Someone suggested the PHYS(2) system call for accessing physical
						+
addresses from user processes. This is a Uniplus   'feature', not a System
V 'feature'. Don't expect to see it in a port done by someone other than
Unisoft. (Mind you it is a neat idea, just right for mapping in such things
as bit mapped graphics, device registers, floating point boards .....)
