Build and boot tested on a variety of arm32 and arm64 platforms using
kernelci.org.  The previous THUMB2_KERNEL=y build failures are gone.

Tested-by: Kevin Hilman <khilman@linaro.org>

kernelci.org results:

Build: http://kernelci.org/build/arm-soc/kernel/v4.4-rc3-4-gccfbab1c1ebd/
Boot: http://kernelci.org/boot/all/job/arm-soc/kernel/v4.4-rc3-4-gccfbab1c1ebd/

(NOTE: the boot failures there appear to be lab-related issues, not related tot his patch.)
