radeon: Fix CP byte order on big endian architectures with KMS.
agp/uninorth: Handle user memory types.
drm/ttm: Add some powerpc cache flush code.
radeon: Enable modesetting on non-x86.
drm/radeon: Respect AGP cant_use_aperture flag.
drm: EDID endianness fixes.
drm/radeon: this VRAM vs aperture test is wrong, just remove it.
