  SVN rev 213383 on 2010-10-03 16:02:53Z by nwhitehorn
  
  Add a memory-range interface to /dev/mem on PowerPC using PAT attributes.
  Unlike actual MTRR, this only controls the mapping attributes for
  subsequent mmap() of /dev/mem. Nonetheless, the support is sufficiently
  MTRR-like that Xorg can use it, which translates into an enormous increase
  in graphics performance on PowerPC.
