Subject: [GIT PULL] drm-vc4-next-2016-07-15 (loops)

Thanks for pulling the other changes.  Here's my last set of new code
for 4.8, my series for enabling real loops in GLSL.  This is pretty
exciting, as it's a major hardware feature that the closed source
driver never supported.

The commits are quite fresh, as kbuild test robot caught a stray ';'
that I cleaned up.  I booted it and touch-tested loops after fixing.

The following changes since commit deb4765db386db67626ffd075d8b5eb5fdf9c4f6:
