Hi all,

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

drivers/gpu/drm/cirrus/cirrus.c: In function 'cirrus_fb_blit_rect':

Caused by commit

  ab3e023b1b4c ("drm/cirrus: rewrite and modernize driver.")

I have marked that driver BROKEN for today.
