Subject: [PATCH v2 0/3] perf bench numa: make possible testing on uneven and/or overlapping CPU ranges

This series allows running the tool on some configurations
that do not conform to an assumption each node contains
nr_cpus/nr_nodes CPUs at most. Instead, the actual node-to-
CPU mapping is acquired dynamically.

patch 1 fixes the described issue
patches 2,3 are follow-up fixes

Changes since v1:
  - numa01* and numa02* test names left intact;
  - "2x3-convergence" fix moved out to separate patch

Alexander Gordeev (3):
  perf bench numa: use numa_node_to_cpus() to bind tasks to nodes
  perf bench numa: fix number of processes in "2x3-convergence" test
  perf bench numa: fix benchmark names
