    kernel - Enhance CPUMASK and atomic ops
    
    * Add atomic_testandset_long()
      Add atomic_testandclear_long()
    
    * Add atomic_cmpxchg_long_test().  This is for debugging only, it uses the
      'z' flag instead of comparing old-vs-result.  But they should have the
      same effect.
    
    * Add macros for atomic_store_rel_cpumask() and atomic_load_acq_cpumask().
    
    * Add ATOMIC_CPUMASK_TESTANDSET()
      Add ATOMIC_CPUMASK_TESTANDCLR()
      Add ATOMIC_CPUMASK_COPY()
