================================================================================

modify the OPAL_PAFFINITY_PROCESS_IS_BOUND macro to search the cpuset for
the maximum possible number of cpus rather than just the number of cpus
currently online.  This corrects a problem where mpi_paffinity_alone was
not working properly on systems in which there can be cpu namespaces with
holes, such as on ppc64 with smt off (as discussed in #2365).

This commit was SVN r22927.
