[Patch] DRM support for addressing >32 bits on 32 bit cores (Radeon DRM driver+TTM)

[Andrej Krutak]

Hello,

I was advised to send this stuff here ( 
https://bugs.freedesktop.org/show_bug.cgi?id=18154 ).

The patches are tested with a P3041 board and a TURKS radeon card. It appears 
that the radeon driver is already generic enough (so no major changes were 
needed there), fortunately.

I think esp. the TTM patch is clearly needed, but it may be incomplete...
