Subject[GIT PULL] nohz: A few improvements v4
Date
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
