I've gone through the patch series and I think it is good to go with a 
couple of minor changes I've suggested in the reviews.  I've mostly 
deferred to Szabolcs' review for 5/6 and 6/6 since they're aarch64-specific.

The changes are small enough that you could commit with the changes. 
However, please post the series that you commit so that we know what 
went in finally.

Thanks,
