    Subject[PATCH 0/5] mm: Cleanup & allow modules to hotplug memory
    Date
    From: Alastair D'Silva <alastair@d-silva.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
