In the process of adding GEM support for OMAP DRM driver, I noticed that I was adding code for creating/freeing mmap offsets which was virtually identical to what was already duplicated in i915 and gma500 drivers.
Rather than duplicating the code a 3rd time, it seemed like a good idea to move it to the GEM core.
Note that I don't actually have a way to test psb or i915, but the changes seem straightforward enough.

For the curious, OMAP DRM driver is here: https://github.com/robclark/kernel-omap4/commits/linux-omap-3.0-drm
I'll send patches when it's dependencies are merged and it is slightly more than half baked ;-)
