Subject: linux-next: manual merge of the bitmap tree with the arm64 tree

Hi all,

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

  include/linux/gfp.h

between commit:

  70c248aca9e7 ("mm: kasan: Skip unpoisoning of user pages")

from the arm64 tree and commit:

  34973181c728 ("headers/deps: mm: Split <linux/gfp_types.h> out of <linux/gfp.h>")

from the bitmap tree.

I fixed it up (I used the latter version of this files and applied the
following merge resolution patch) 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.
