It looks like all but the last two (msm specific) patches have at
least a-b or r-b.. I'll try and get someone to look at those last two

Any thoughts about preferred way to land this.  I currently have a few
of the msm patches which don't depend on core patches in
msm-next-staging, but I can drop those before it gets pushed to
msm-next.  Maybe we want a topic branch that both msm and i915 can
pull into their -next branches?

BR,
-R
