Mapping virtual addresses to physical

["Alan Casey" <alan.casey5@xxxxxxxxxxx>]

Hi,

  I have used code similar to the devmem2.c example at
  www.simtec.co.uk/appnotes/AN0014/ to map physical
  addresses to virtual addresses (i.e. user space pointers) 
  but am just wondering how do you do the reverse - i.e.
  map virtual addresses to physical addresses in a user
  space program without writing a device driver??

  Any info. appreciated,
  Regards,
  Alan.
