linux-next: manual merge of the mm tree with the efi tree

Hi all,

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

  mm/internal.h

between commit:

  902c2d91582c ("memblock: Disable mirror feature if kernelcore is not specified")

from the efi tree and commit:

  9a4722162210 ("mm/mprotect: fix soft-dirty check in can_change_pte_writable()")

from the mm tree.

I fixed it up (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.
