Sorry for the delay.  I thought RPi world was exceptionally quiet, but
in fact I had issues with my newly setup mailbox and filters.  All
rectified now in any case.

It might be worth noting that this will not likely land in v3.19, as
we are one step removed from Linus (i.e. via ARM SoC) and they usually
like to have pull-requests in by -rc5.  Unless anyone stamps their
feet, I'll be sending this no sooner than v3.20.

Patch applied, thanks.
