[PATCH v2 0/4] mm, memory_hotplug: handle unitialized numa node gracefully

[Michal Hocko]

Hi,
this should be the full bundle for now. I have ended up with 4 patches.
The primary fix is patch 2 (should be reasonably easy to backport to
older kernels if there is any need for that). Patches 3 and 4 are mere
clean ups.

I will repost once this can get some testing from Alexey. Shouldn't be
too much different from http://lkml.kernel.org/r/YbHfBgPQMkjtuHYF@xxxxxxxxxxxxxx
with the follow up fix squashed in.

I would really appreciate to hear more about http://lkml.kernel.org/r/YbMZsczMGpChaWz0@xxxxxxxxxxxxxx
because I would like to add that information to the changelog as well.

Thanks for the review and testing.
