This is the latest patches to be queued for 3.12.
A little late, but as Dave Jones has been stumbling over this for a
while, I thought it would be good to get it in now. It's not that
complex to resolve any issues that may pop up.
I'll keep it in linux-next for a while to make sure it really is clean.
Note, the checker will stumble over a few functions in irq and scheduler
code if enabled. This is because those patches have not received Acks
from Thomas Gleixner and Peter Zijlstra. When I get those acks, I'll
add the changes to silent those too.
Thanks to Paul McKenney for reviewing the patches.
Enjoy,
