I'm not sure what's happened to the drm code in linux-next - it's exploding all over the place. Did someone turn on -Werror without doing anywhere near enough testing?
Anyway, I don't know how to fix this i386 build error:
drivers/gpu/drm/i915/i915_gem_gtt.c: In function 'gen8_ppgtt_init': drivers/gpu/drm/i915/i915_gem_gtt.c:954:2: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
ppgtt->base.total = 1ULL << 32;
i915_address_space.total is a ulong: 32-bit.

Seems like you have CONFIG_DRM_I915_WERROR set?
We explicitely made sure to not enable -Werror by default, because different versions of gcc will generate different set of warnings making it roughly impossible to use -Werror by default (say, newer versions of gcc with more clever warnings trying to compile old commits while bisecting)

Yes.
We explicitely made sure to not enable -Werror by default,
`make allmodconfig' enables CONFIG_DRM_I915_WERROR.
I'm not sure what is the approved way of fixing this. Perhaps disabling CONFIG_DRM_I915_WERROR when CONFIG_COMPILE_TEST=y.

Right.

Maybe the answer right now is to just drop that config. Daniel?
BR, Jani.

Agreed, that little experiment doesn't seem to be worth the trouble. I've pushed/sent-out the revert.
Thanks, Daniel
