[LTP] [PATCH 0/2] numa_helper: get nodes with mem/cpu/both

[Jan Stancek <jstancek@redhat.com>]

numa_helper has been used for syscalls testcases, which
care about nodes with memory. Based on discussion here:
http://article.gmane.org/gmane.linux.ltp/16325
it was deemed, that 'flag' extension would be useful,
to allow tests to ask for nodes with memory/cpu/both.

This patch series is introducing flag to get_allowed_nodes().

For example, a config like this one:
  # numactl -H
  available: 3 nodes (2,4-5)
  node 2 cpus: 0
  node 2 size: 511 MB
  node 2 free: 88 MB
  node 4 cpus:
  node 4 size: 256 MB
  node 4 free: 34 MB
  node 5 cpus:
  node 5 size: 255 MB
  node 5 free: 59 MB

would return:
  nodes (flag=0): 2 4 5 (any)
  nodes (flag=1): 2 4 5 (mem)
  nodes (flag=2): 2     (cpus)
  nodes (flag=3): 2     (mem and cpus)

Tested with:
numactl-devel-0.9.8-7.el5
numactl-devel-2.0.3-9.el6
numactl-devel-2.0.7-6.el7

numa_node_to_cpus() is broken in older libnuma < 1, so cpumap
is used instead.

Next step (not part of this series) is to move it outside
syscalls area, so it can be used by other testcases.
