    Subject[GIT PULL] Introduce housekeeping subsystem v4
    Date
    Ingo,

    Please pull the core/isolation-v4 branch that can be found at:

    git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
    core/isolation-v4

    HEAD: cf4c55aad44251369c8507c3823f9f9c51d4dc77

    Summary of changes:

    * Move the housekeeping code that was tied to NO_HZ to its own subsystem.
    Currently NO_HZ governs the other isolation features which is not right
    as dynticks is just an isolation feature like the others. We want to
    centralize the CPU isolation decisions to a subsystem of its own instead.

    * Integrate isolcpus code to housekeeping and treat it as a CPU isolation
    feature.

    * Reuse the "isolcpus=" kernel parameter to control the CPU isolation.
    For now only tick and domains can be isolated after this patchset:

    isolcpus=1-7 # isolate domains on CPU range 1 to 7
    # "domain" flag is implicit by default to
    # keep the current behaviour

    isolcpus=domain,1-7 # do the same

    isolcpus=nohz,1-7 # apply nohz_full to CPU range 1 to 7

    isolcpus=nohz,domain,1-7 # apply nohz_full and isolate domains of
    # CPU range 1 to 7

    Thanks,
    Frederic

    housekeeping: Move housekeeping related code to its own file
    watchdog: Use housekeeping_cpumask() instead of ad-hoc version
    housekeeping: Provide a dynamic off-case to housekeeping_any_cpu()
    housekeeping: Make housekeeping cpumask private
    housekeeping: Use its own static key
    housekeeping: Rename is_housekeeping_cpu to housekeeping_cpu
    housekeeping: Move it under its own config, independant from NO_HZ
    housekeeping: Introduce housekeeping flags
    housekeeping: Handle nohz_full= parameter
    housekeeping: Move isolcpus to housekeeping
    housekeeping: Add basic isolcpus flags
    housekeeping: Document isolcpus flags
