  Handle the fictitious pages created by the device pager.  For fictitious
  pages which represent actual physical memory we must strip off the fake
  page in order to allow illegal aliases to be detected.  Otherwise we map
  uncacheable in the virtual and physical caches and set the side effect bit,
  as is required for mapping device memory.
  This fixes gstat on sparc64, which wants to mmap kernel memory through a
  character device.
