    Subject[RFC][PATCH 00/32] Nohz cpusets v2 (adaptive tickless kernel)
    Date
    *** BLURB HERE ***

    Frederic Weisbecker (32):
    nohz: Separate idle sleeping time accounting from nohz logic
    nohz: Make nohz API agnostic against idle ticks cputime accounting
    nohz: Rename ts->idle_tick to ts->last_tick
    nohz: Move nohz load balancer selection into idle logic
    nohz: Move ts->idle_calls incrementation into strict idle logic
    nohz: Move next idle expiry time record into idle logic area
    cpuset: Set up interface for nohz flag
    nohz: Try not to give the timekeeping duty to an adaptive tickless
    cpu
    x86: New cpuset nohz irq vector
    nohz: Adaptive tick stop and restart on nohz cpuset
    nohz/cpuset: Don't turn off the tick if rcu needs it
    nohz/cpuset: Wake up adaptive nohz CPU when a timer gets enqueued
    nohz/cpuset: Don't stop the tick if posix cpu timers are running
    nohz/cpuset: Restart tick when nohz flag is cleared on cpuset
    nohz/cpuset: Restart the tick if printk needs it
    rcu: Restart the tick on non-responding adaptive nohz CPUs
    rcu: Restart tick if we enqueue a callback in a nohz/cpuset CPU
    nohz: Generalize tickless cpu time accounting
    nohz/cpuset: Account user and system times in adaptive nohz mode
    nohz/cpuset: New API to flush cputimes on nohz cpusets
    nohz/cpuset: Flush cputime on threads in nohz cpusets when waiting
    leader
    nohz/cpuset: Flush cputimes on procfs stat file read
    nohz/cpuset: Flush cputimes for getrusage() and times() syscalls
    x86: Syscall hooks for nohz cpusets
    x86: Exception hooks for nohz cpusets
    x86: Add adaptive tickless hooks on do_notify_resume()
    nohz: Don't restart the tick before scheduling to idle
    rcu: New rcu_user_enter() and rcu_user_exit() APIs
    rcu: New rcu_user_enter_irq() and rcu_user_exit_irq() APIs
    rcu: Switch to extended quiescent state in userspace from nohz cpuset
    nohz: Exit RCU idle mode when we schedule before resuming userspace
    nohz/cpuset: Disable under some configs
