With the COMPILE_TEST patch, but without the extra fix I get:

cc1: some warnings being treated as errors
This is with a freshly pulled tree from drm-exynos.git exynos-drm-next
The warning only appear if you build for alpha.
So the extra fix is indeed needed. But always good to double check -
thanks for asking.
Note:
My gcc version for alpha:
$ alpha-linux-gnu-gcc --version
alpha-linux-gnu-gcc (Ubuntu 8.3.0-6ubuntu1) 8.3.0
