Subject: [PATCH 0/5] mm: Cleanup & allow modules to hotplug memory

From: Alastair D'Silva <alastair@...ilva.org>

This series addresses some minor issues found when developing a
persistent memory driver.

As well as cleanup code, it also exports try_online_node so that
it can be called from driver modules that provide access to additional
physical memory.

Alastair D'Silva (5):
  mm: Trigger bug on if a section is not found in __section_nr
  mm: don't hide potentially null memmap pointer in
    sparse_remove_one_section
  mm: Don't manually decrement num_poisoned_pages
  mm/hotplug: Avoid RCU stalls when removing large amounts of memory
  mm/hotplug: export try_online_node
