MPS issue job003993

TitleRestrictions on maximum pool alignment are not checked or documented
Assigned userRichard Brooksby
DescriptionThe MV, MVFF, and MVT pool classes offer the MPS_KEY_ALIGN keyword for setting "the alignment of addresses for allocation (and freeing)". MVT and MVFF document a minimum, but no maximum alignment. In fact, the MPS will not honour requests for alignment greater than the arena grain size, because there is no interface to allocate from the arena with an alignment.
AnalysisDocument the restriction and its relationship to MPS_KEY_ARENA_GRAIN_SIZE.
Check requested alignments.
