Alright, thanks!

I will re-spin the series and post a new version once 4.19 rc1 is out.
Hopefully we can queue it up early in next cycle to get it tested in
next for a while.

Actually, patch 10 and patch11 is ready to go as well. I ping Daniel
on patch 12.

In regards to the rest of the series, some of the PSCI/ARM changes
have been reviewed by Mark Rutland, however several changes have not
been acked.

On the other hand, one can also interpret the long silence in regards
to PSCI/ARM changes as they are good to go. :-)

Kind regards
