So, just as I thought...

-rc6 has now been released, and YOU have done NOTHING to resolve any of
the issues you have with this patch set - which is precisely on track
with how you have behaved towards this set of changes on the past - where
you promised imformation/patches and never delivered.

Well, right now I'm just not going to *care* one bit about Prima2.  If
this patch set breaks it, tough.  You've had plenty of opportunity to
deal with this, but instead you've chosen to just whinge about it and
then do precisely nothing to assist.

So, Prima2 *is* going to get *broken*.  No platform or SoC is important
enough to stand in the way of core ARM changes beneficial to the rest of
the community.

We've lost around 4 weeks testing time in linux-next because of this...
frankly I don't give a damn right now, all I care about is getting these
patches out of my tree and into mainline during the next merge window.
Any issues that come up can be debugged and fixed afterwards - and the
debugging *has* to be done by the SoC people because I don't have any
way to test and debug it on individual SoCs.  (And Olof's test farm is
not sufficient for diagnosis.)
