    [PATCH] s390: cpu-idle notifier · 1ef8b835
    Martin Schwidefsky authored
    This patch introduces a notifier chain for cpu idle.  There are two events
    CPU_IDLE and CPU_NOT_IDLE that are called just before the cpu goes to sleep
    and right after the cpu woke up again.  The notifier is used to simplify the
    no-hz-timer-in-idle feature and the virtual cpu timers.  In addition the
    virtual cpu timer functions have been moved to arch/s390/kernel/vtime.c, which
    gives a nice separation between the timer functions related to real time and
    the timer functions related to virtual cpu time.
