* compute mmap-file size more wisely and pass requested size to allocator * change MCA parameters: - get rid of mpool_sm_per_peer_size - get rid of mpool_sm_max_size - set default mpool_sm_min_size to 0 * no longer pad sm allocations to page boundaries * have sm_btl_first_time_init check return codes on free-list creations Have mca_btl_sm_prepare_src() check to see if it can allocate an EAGER fragment rather than a MAX fragment if the smaller size works. Remove ompi/class/ompi_[circular_buffer_]fifo.h and references thereto. Remove opal/util/pow2.[c|h] and references thereto. This commit was SVN r20614.
