If object A contains B + I/O as children, we can "ignore" I/Os and still try to merge A and B. We now do the same for Misc objects without cpusets instead of I/Os. This fixes a corner case when export/reimport to XML creates a slightly different topology (making hwloc_insert_misc fail inside a Linux cgroup). Thanks to Dave Love for reporting the problem. Fixes #118 (cherry picked from commit open-mpi/hwloc@650371e115) Signed-off-by: Jeff Squyres <jsquyres@cisco.com>
