  Log:
  Add the superpage reservation system.  This is "part 2 of 2" of the
  machine-independent support for superpages.  (The earlier part was
  the rewrite of the physical memory allocator.)  The remainder of the
  code required for superpages support is machine-dependent and will
  be added to the various pmap implementations at a later date.
  
  Initially, I am only supporting one large page size per architecture.
  Moreover, I am only enabling the reservation system on amd64.  (In
  an emergency, it can be disabled by setting VM_NRESERVLEVELS to 0
  in amd64/include/vmparam.h or your kernel configuration file.)
