Be aware that as of v3.11-rc2 this doesn't cleanly apply, as the __cpuinit removal broke the final patch's context in a couple of places. It would be nice to get rid of the new cpuinit additions too... With that cleaned up locally, I've gave this a spin on tc2 and a Foundation model to test the cp15/system timers, hotplugging CPUs and running a basic test (`time sleep 5`). That all seems to work. Unfortunately I have no way of testing the memory-mapped timer support, but I trust you've tested that locally.
