Subject: linux-next: manual merge of the akpm-current tree with the hmm tree

Hi all,

Today's linux-next merge of the akpm-current tree got a conflict in:

  mm/memory_hotplug.c

between commit:

  514caf23a70f ("memremap: replace the altmap_valid field with a PGMAP_ALTMAP_VALID flag")

from the hmm tree and commit:

  db30f881e2d7 ("mm/hotplug: kill is_dev_zone() usage in __remove_pages()")

from the akpm-current tree.

I fixed it up (I think - see below) and can carry the fix as
necessary. This is now fixed as far as linux-next is concerned, but any
non trivial conflicts should be mentioned to your upstream maintainer
when your tree is submitted for merging.  You may also want to consider
cooperating with the maintainer of the conflicting tree to minimise any
particularly complex conflicts.
