[PATCH v2 0/3] mm: Cleanup & allow modules to hotplug memory

["Alastair D'Silva" <alastair@au1.ibm.com>]

From: Alastair D'Silva <alastair@d-silva.org>

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

Changelog:
V2:
  - Drop mm/hotplug: export try_online_node
        (not necessary)
  - Return errors from __section_nr
  - Remove errant whitespace change in
        mm: don't hide potentially null memmap pointer
  - Rework mm: don't hide potentially null memmap pointer
    to use a start & count
  - Drop mm/hotplug: Avoid RCU stalls when removing large amounts of memory
        (similar patch already went in)

Alastair D'Silva (3):
  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
