Very good! I have queued these and pushed them to -rcu on github (https://github.com/paulmckrcu/linux) branch rcu/dynticks.
Some of the Power boxes are now back in the land of the living, and will hopefully work their way through their testing backlogs some time soon. ;-) At which point, I will restart PowerPC testing.
Thanx, Paul
