Subject: [PATCH V3 0/3] Refine numa_emulation

My previous patch "x86/mm/numa: Remove numa_nodemask_from_meminfo()" hits a
problem in numa_emulation. The reason is numa_nodes_parsed is not set
correctly after emulation.

This patch set tries to fix this and also with two code refine.

Detailed discussions are in this thread:

    https://lkml.org/lkml/2017/3/13/1230

and test result is posted :

    https://lkml.org/lkml/2017/4/10/641

V3:
    * remote the error branch and split the loop into a function
    * refine the comment

V2:
    * refresh the change log based on David comments
    * use nodes_clear()

Wei Yang (3):
  x86/numa_emulation: refine the calculation of max_emu_nid and
    dfl_phys_nid
  x86/numa_emulation: assign physnode_mask directly from
    numa_nodes_parsed
  x86/numa_emulation: restructures numa_nodes_parsed from emulated nodes
