May be some of the update_nohz_rq_clock() calls here could even apply to mainline for dynticks idle CPUs. There are still two known places I need to look into for which I had patches in my nohz tree but I need to have a deeper look into these (make the patch saner, check if the problem should be fixed in mainline instead, etc...): * http://git.kernel.org/cgit/linux/kernel/git/frederic/linux-dynticks.git/commit/?h=3.9-rc1-nohz1&id=36ca34d0d4ba0a9589cf3054a7df9f0879ddd6c5 * http://git.kernel.org/cgit/linux/kernel/git/frederic/linux-dynticks.git/commit/?h=3.9-rc1-nohz1&id=9c3af3b4104682217b1f602acb4efbab563ccf59 But otherwise this patchset handles the big bulk of rq clock handling.
