  Modified files:
    sys/conf             files.sparc64 
    sys/sparc64/include  cache.h pmap.h smp.h 
    sys/sparc64/sparc64  cache.c mp_exception.S 
  Added files:
    sys/sparc64/sparc64  cheetah.c spitfire.c 
  Log:
  - Remove unused cache flushing routines.  These will not necessary work
    on future UltraSPARC cpus for which the data cache is not direct mapped.
  - Move UltraSPARC I and II (spitfire, blackbird, sapphire, sabre) specific
    functions to spitfire.c, and add cheetah.c for UltraSPARC III specific
    functions.  Initially just cache flushing, but there are a few other
    functions that will need to move here.
  - Add an ipi handler for data cache flushing on UltraSPARC III.
  - Use function pointers to select the right cache flushing functions based
    on cpu_impl.
  
  With this it is possible to boot single user from an mfs root on UltraSPARC
  III systems, including spinning up secondary processors.  There is currently
  no support for the host to pci bridge, and no documentation for it is
  publically available.
  
  Thanks to Oleg Derevenetz for providing access to a system with UltraSPARC
  III+ cpus.
