    [PATCH] get/put_cpu methods · 79eb6a12
    Robert Love authored
    This implements a get_cpu() and matching put_cpu() to safely hand out
    the current CPU to avoid preempt races.  Andrew and I have been bitching
    about the need for such a method.
    
    I also went ahead and replaced an example of current explicit
    preempt-off with the new methods, as a case in point.
