Ingo,
Please pull the nohz/core branch (on top of tip:timers/core) that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git nohz/core
HEAD: 60d0b4dc36259029e4cc8d030d8f59b33a119814
--- Summary of changes:
* Fix rare crashes due to context tracking recursion when faulting on vmalloc'ed areas. * Simplify the TIF_NOHZ propagation (less context switch overhead) * Set nohz full CPUs as isolcpus. This way we enforce nohz CPUs to be undisturbed by globally affine tasks.
Thanks, Frederic ---
