git: kernel - Use atomic op for usched_global_cpumask
commit cb31dff3c5e12b338b6832cfde4445d76ea2b317

kernel - Use atomic op for usched_global_cpumask
* Use atomic op for usched_global_cpumask in the cpu init code. This
code is serialized anyway, I think, but it is best to be safe.
* Add cpu_ccfence() to ensure that the compiler does not reorder the
clearing of the mask in the cpusync code.
