Hi all,

Please, find couple of fixes to the tool. Note, I did not bother
fixing leaked memory allocated with numa_allocate_cpumask().

Alexander Gordeev (3):
  perf bench numa: fix incorrect NUMA toplogy assumption
  perf bench numa: fix benchmark names
  perf bench numa: fix wrong benchmark configuration

The current code assumes that CPUs are evenly spread among
NUMA nodes. That is generally incorrect and leads to failure
on systems that have different NUMA topology.

Several benchmarks have names that do not correspond to
their configuration. Fix that and also some whitespace
inconsistencies.

This update fixes a wrong number of processes for one
benchmark and consolidates two others in a unified way.

The current code assumes that CPUs are evenly spread among
NUMA nodes. That is generally incorrect and leads to failure
on systems that have different NUMA topology.
