Thanks, Simon, it's much appreciated.

Arnd, Olof, are you happy to pick this up for v3.20? I believe all the
patches have now been appropriately acked.

If it makes things any easier I've placed the series (with new acks) on
my arm/perf/platform-updates branch [2], based atop of v3.19-rc4.

Thanks,
Mark.
