Full build log

I'm using OBS service for building Linux kernel. There is a repository:
https://build.opensuse.org/package/show/home:linux4humans:pf-kernel/kernel-pf
You can see building success with openSUSE 42 and SLES 12 build farms, hovewer
it fail with SLES 11 build farm.

../drivers/gpu/drm/i915/i915_gem_gtt.c:2438: error: 'gtt_entry' may be used
uninitialized in this function

../drivers/gpu/drm/i915/i915_gem_gtt.c:2341: error: 'gtt_entry' may be used
uninitialized in this function
make[6]: *** [drivers/gpu/drm/i915/i915_gem_gtt.o] Error 1

I hope that you didn't dropped GCC 4.3. Anyway, I have a suspicion that an
error will be present on newer GCC versions with harder build requirements.
