Subject: [PATCH v4 0/4] Refactoring for remove_memory_section/unregister_mem_sect_under_nodes

v3 -> v4:
        - Make nodemask_t a stack variable
        - Added Reviewed-by from David and Pavel

v2 -> v3:
        - NODEMASK_FREE can deal with NULL pointers, so do not
          make it conditional (by David).
        - Split up node_online's check patch (David's suggestion)
        - Added Reviewed-by from Andrew and David
        - Fix checkpath.pl warnings

This patchset does some cleanups and refactoring in the memory-hotplug code.

The first and the second patch are pretty straightforward, as they
only remove unused arguments/checks.

The third patch refactors unregister_mem_sect_under_nodes a bit by re-defining
nodemask_t as a stack variable. (More details in Patch3's changelog)

The fourth patch removes a node_online check. (More details in Patch4's changelog)
Since this change has a patch for itself, we could quickly revert it
if we notice that something is wrong with it, or drop it if people
are concerned about it.

Oscar Salvador (4):
  mm/memory-hotplug: Drop unused args from remove_memory_section
  mm/memory_hotplug: Drop mem_blk check from
    unregister_mem_sect_under_nodes
  mm/memory_hotplug: Define nodemask_t as a stack variable
  mm/memory_hotplug: Drop node_online check in
    unregister_mem_sect_under_nodes
