Good, thanks. This means that the xtensa ccount sched_clock patch 
(http://lists.linux-xtensa.org/pipermail/linux-xtensa/Week-of-Mon-20130617/001077.html) 
that depends on the third patch in this series, can go in for 3.11, if the 
xtensa maintainer acks it (added to Cc). How should we handle the dependency 
then?
