Hmm, patch 05/14 depends on the existence of the new word.  That's a non-issue
if you're planning on taking this for 5.11.  If it's destined for 5.12, maybe
get an ack from Paolo on patch 05 and take both through tip?  I can drop them
from this series when I send v3.  In hindsight, I should have split these two
patches into a separate mini-series from the get-go.

Thanks!
