  SVN rev 211453 on 2010-08-18 12:52:21Z by jchandra
  
  MIPS n64 support - continued...
  
  1. On n64, use XKPHYS to map page table pages instead of KSEG0. Maintain
     just one freepages list on n64.
  
     The changes are mainly to introduce MIPS_PHYS_TO_DIRECT(pa),
     MIPS_DIRECT_TO_PHYS(), which will use KSEG0 in 32 bit compilation
     and XKPHYS in 64 bit compilation.
  
  2. Change macro based PMAP_LMEM_MAP1(), PMAP_LMEM_MAP2(), PMAP_LMEM_UNMAP()
    to inline functions.
  
  3. Introduce MIPS_DIRECT_MAPPABLE(pa), which will further reduce the cases
     in which we will need to have a special case for 64 bit compilation.
  
  4. Update CP0 hazard definitions for CPU_RMI - the cpu does not need any
     nops
