    Subject[PATCH 0/7] nohz: Tick dependency mask v3
    Date
    This series changes the nohz full infrastructure to let subsystems notify
    when they have a tick dependency. Checking if we can stop the tick is thus
    perfomed in a push rather than a pull model, see previous iterations:
    http://lkml.kernel.org/r/1437669735-8786-1-git-send-email-fweisbec@gmail.com

    Changes here:

    * Reuse fetch_or()
    * Change posix cpu timers to a per thread and signal dependency (we may
    want to merge all that to thread level only) instead of global dependency.
    * Scheduler tick dependency now is evaluated at the CPU level instead
    of the task level. We don't anymore depend on the current task policy
    but on the whole tasks of the runqueue. That too can be further optimized.

    Only lightly tested, just checking for current state opinions.

    HEAD: ca9e998d0be7e6ef1ffab888436cbabf5446c865

    Thanks,
    Frederic
