Commit Message

wreck: restrict topology before applying cpumask

Problem: the wreck cpu-affinity support doesn't restrict the topology
to the current process' cpuset before doing affinity binding, and
so expects the core ids assigned by the scheduler to be in "whole
system" logical order. Since the scheduler assigns cores indexed from
0 per-rank, this breaks the case where multiple brokers are run per
real physical node.

Fix this problem by first restricting the hwloc topology to the
current cpus allowed mask. The at least there is a change libhwloc
will use the same numbering scheme for cores as is being used by
the scheduler.
