Thanks. I've squashed that into the patch in target-arm.next.

I plan to send this as part of a pullreq for rc1 tomorrow probably
midday-ish UK time, unless somebody speaks up now to say they'd
rather have more time for review/testing/whatever. (That wouldn't
mean it missed 6.1, as a bugfix-of-sorts this can go in rc2 if
necessary.)
