The patches apply cleanly back to v3.6.

Joseph Lo had 2 minor comments on patch 2 (changing Tegra3 to Tegra20
in the commit message, replacing cpuidle_coupled_poke_pending with
cpuidle_coupled_poked in the comment above cpuidle_coupled_poked), do
you want to fix those up locally or should I resend the series?
