Change 23662 by marcel@marcel_nfs on 2003/01/12 20:48:51

	Add SPARSE_PHYSICAL_MEMORY.
	This option guards the code changes that deal with sparse memory
	systems. For the VM system this has an affect on the VM page
	array and the mapping from physical address to vm_page pointer.
	
	Also, machine dependent code that builds phys_avail can make
	use of this option to accept or reject memory regions if it
	would create a sparse physical address space.
