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

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

Hi all,

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

  arch/x86/Kconfig

between commits:

  9e2b4be377f0 ("ima: add a new CONFIG for loading arch-specific policies")

from the integrity tree and commit:

  faaa52178603 ("userfaultfd: wp: add WP pagetable tracking to x86")

from the akpm-current 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.

Note that I put the selects in their correct alphabetical position as
asked by the comment higher up in the file.  If that had been done in
the patches, then there would have been no conflicts ...

Cheers,
Stephen Rothwell

True.  Thanks, Stephan.  Before moving it to "its proper location",
I'm wondering if there should be a separate section for "imply".
