    smp: Rename __smp_call_function_single() to smp_call_function_single_async() · c46fff2a
    Frederic Weisbecker authored
    The name __smp_call_function_single() doesn't tell much about the
    properties of this function, especially when compared to
    smp_call_function_single().
    
    The comments above the implementation are also misleading. The main
    point of this function is actually not to be able to embed the csd
    in an object. This is actually a requirement that result from the
    purpose of this function which is to raise an IPI asynchronously.
    
    As such it can be called with interrupts disabled. And this feature
    comes at the cost of the caller who then needs to serialize the
    IPIs on this csd.
    
    Lets rename the function and enhance the comments so that they reflect
    these properties.
