[PATCH] new radeon memory map fixes

[Michel Dänzer]

Hi Ben,

haven't got around to testing the patches, but they basically look good
to me. Some comments:

There should be no need to check for info->cursor_offset == 0 in the
cursor functions. Longer term, I think we should just reserve a static
FB region for the cursor upfront instead of going through all these
hoops with EXA.

Also, unless I'm missing something, you're removing the code that forces
the display priority to high for Radeon 7200.

The way you handle backwards compatibility here is brilliant, thanks.
The only minor issue I see is that the setparam ioctl can be called by
unprivileged clients, but that applies to the existing colour tiling
part as well, and it may not be a problem thanks to the offset fixups.
