[ Upstream commit ccf09357ffef2ab472369ab9cdf470c9bc9b821a ]
The smp_call_function_many() kerneldoc comment got out of sync with the function definition (bool parameter "wait" is incorrectly described as a bitmask in it), so fix it up by copying the "wait" description from the smp_call_function() kerneldoc and add information regarding the handling of the local CPU to it.
