  Modified files:
    sys/powerpc/include  sr.h vmparam.h 
    sys/powerpc/powerpc  pmap.c 
  Log:
  Increase kernel VA from 256Mb to 512Mb by shifting the segment used
  for user copyinout down to 12, and keeping segments 13/14 for
  kernel VA.
  
  It would be nice to have more available, but segments lower than
  this are reserved for either memory or 1:1 mapped device i/o,
  and seg 15 is OpenFirmware ROM. Also, the effort to keep OpenFirmware
  available for callbacks limits the use of VA-mapped segments.
  Fortunately UMA_MD_SMALL_ALLOC takes away a lot of VM pressure.
