I am on some Samsung's proprietary hardware which suffers from this problem. Actually it has "weird GIC", similar to Exynos-4 (every CPU accesses GIC at its own base), thus hardware vGIC is unusable. I learned about RPi-2 when i was discussing some related things earlier with Andre over private mail and we suggested that it could be useful there.
