    vtime: Make vtime_account_system() irqsafe · 11113334
    Frederic Weisbecker 提交于
    vtime_account_system() currently has only one caller with
    vtime_account() which is irq safe.
    
    Now we are going to call it from other places like kvm where
    irqs are not always disabled by the time we account the cputime.
    
    So let's make it irqsafe. The arch implementation part is now
    prefixed with "__".
    
    vtime_account_idle() arch implementation is prefixed accordingly
    to stay consistent.
