Hi all,

After merging the drm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

arch/powerpc/platforms/embedded6xx/Kconfig:2:error: recursive dependency detected!
arch/powerpc/platforms/embedded6xx/Kconfig:2: symbol EMBEDDED6xx depends on BROKEN_ON_SMP
init/Kconfig:79: symbol BROKEN_ON_SMP depends on BROKEN
init/Kconfig:76: symbol BROKEN is selected by DRM_I915_DEBUG
drivers/gpu/drm/i915/Kconfig.debug:20: symbol DRM_I915_DEBUG depends on DRM_I915
drivers/gpu/drm/i915/Kconfig:2: symbol DRM_I915 depends on DRM
drivers/gpu/drm/Kconfig:8: symbol DRM depends on AGP
drivers/char/agp/Kconfig:2: symbol AGP depends on PCI
drivers/pci/Kconfig:16: symbol PCI depends on HAVE_PCI
drivers/pci/Kconfig:7: symbol HAVE_PCI is selected by FORCE_PCI
drivers/pci/Kconfig:11: symbol FORCE_PCI is selected by MVME5100
arch/powerpc/platforms/embedded6xx/Kconfig:51: symbol MVME5100 depends on EMBEDDED6xx
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"

Caused by commit

d9d54a530a70 ("drm/i915: Put future HW and their uAPIs under STAGING & BROKEN")

You really should not select BROKEN. It is assumed to always be false
so we can make actually broken code depend on it (and therefore not
be built).

I have used the drm tree from next-20191031 for today.
