You are welcome ... I'll wait until tomorrow to see if Al wants to send this
patch and the patch for the openrisc failure to Linus; if I don't hear back,
I'll do it myself.

Thanks, I have no other fixes for AVR32. But let me know if you want me to
push it through linux-avr32.

I have another related fix (for openrisc), so let me just send both.
I'll do that in an hour or so.
