Subject: [Patch v4 0/8] bugfix for memory hotplug

The last version is here:
    https://lkml.org/lkml/2012/10/19/56

Note: patch 1-3 are in -mm tree and I don't touch them. The other patches
except patch6 are also in mm tree. Patch 6 is not touched.

Changes from v3 to v4:
  Patch4: use dynamically allocated memory instead of static array.
  Patch5: merge [patchv3 2-3] into a single patch, and update it as we use
          dynamically allocated memory
  Patch7: merge [patchv3 5-6] into a single patch
  Patch8: merge [patchv3 9] and its fix into a patch

Changes from v2 to v3:
  Merge the bug fix from ishimatsu to this patchset(Patch 1-3)
  Patch 3: split it from patch as it fixes another bug.
  Patch 4: new patch, and fix bad-page state when hotadding a memory
           device after hotremoving it. I forgot to post this patch in v2.
  Patch 6: update it according to Dave Hansen's comment.

Changes from v1 to v2:
  Patch 1: updated according to kosaki's suggestion

  Patch 2: new patch, and update mce_bad_pages when removing memory.

  Patch 4: new patch, and fix a NR_FREE_PAGES mismatch, and this bug
           cause oom in my test.

  Patch 5: new patch, and fix a new bug. When repeating to online/offline
           pages, the free pages will continue to decrease. 

Wen Congyang (6):
  memory-hotplug: auto offline page_cgroup when onlining memory block
    failed
  memory-hotplug: fix NR_FREE_PAGES mismatch
  numa: convert static memory to dynamically allocated memory for per
    node device
  clear the memory to store struct page
  memory-hotplug: current hwpoison doesn't support memory offline
  memory-hotplug: allocate zone's pcp before onlining pages

Yasuaki Ishimatsu (2):
  memory hotplug: suppress "Device memoryX does not have a release()
    function" warning
  suppress "Device nodeX does not have a release() function" warning
