  Log:
  Define every architecture as either VM_PHYSSEG_DENSE or
  VM_PHYSSEG_SPARSE depending on whether the physical address space is
  densely or sparsely populated with memory.  The effect of this
  definition is to determine which of two implementations of
  vm_page_array and PHYS_TO_VM_PAGE() is used.  The legacy
  implementation is obtained by defining VM_PHYSSEG_DENSE, and a new
  implementation that trades off time for space is obtained by defining
  VM_PHYSSEG_SPARSE.  For now, all architectures except for ia64 and
  sparc64 define VM_PHYSSEG_DENSE.  Defining VM_PHYSSEG_SPARSE on ia64
  allows the entirety of my Itanium 2's memory to be used.  Previously,
  only the first 1 GB could be used.  Defining VM_PHYSSEG_SPARSE on
  sparc64 allows USIIIi-based systems to boot without crashing.
  
  This change is a combination of Nathan Whitehorn's patch and my own
  work in perforce.
