       These  functions  provide hints about the usage of resources that are shared with other processors on the
       Power architecture.  They can be used, for example, if a program waiting on a lock intends to divert  the
       shared resources to be used by other processors.

       __ppc_yield() provides a hint that performance will probably be improved if shared resources dedicated to
       the executing processor are released for use by other processors.

       __ppc_mdoio() provides a hint that performance will probably be improved if shared resources dedicated to
       the  executing processor are released until all outstanding storage accesses to caching-inhibited storage
       have been completed.

       __ppc_mdoom() provides a hint that performance will probably be improved if shared resources dedicated to
       the executing processor are released until all outstanding storage  accesses  to  cacheable  storage  for
       which the data is not in the cache have been completed.
