The mpool/memkind component was using a deprecated "partitions" API. This commit refactors the memkind component to make use of the supported public API. The public API uses 3 parameters to specify a mpool "kind": - a memkind type (which for now is just default or HBM) - a memkind policy - a memkind_bits (partly to specify pagesize) The MCA parameters were changed to reflect these memkind parameters. Add a make check test for sanity checking of the memkind component. Signed-off-by: Howard Pritchard <howardp@lanl.gov>
