I forgot to add, this is a part of a series of patches which updates
the Exynos 5260
support, allowing use of the kernel on secure parts and adding suspend
Version 1 of the patches has been posted to the samsung-soc mailing list:

touches generic ARM files I though I'd better check the approach is acceptable
to a wider audience.
