As the name implies these use mutex xsemantics, just remove the
defines and use mutex_lock/mutex_unlock and mutex_trylock directly
(the latter only if mutex_trylock has the same return value as
spin_trylock, not the broken down_trylock version)
not sure what to do about mutex_init, do you have one in your patches?
mutex_destroy should be a simple no-op.
