Sorry, it seems I missed it. If you didn't merge them yet, I'll
merge it on my tree today, if you think it would be best to have
it together with the patch that enabled FB_OMAP builds with
COMPILE_TEST.

If you prefer, instead, feel free to merge via your tree, as this is
FB stuff anyway.

If you need/want:
