Subject: linux-next: manual merge of the akpm-current tree with the
 powerpc-fixes and powerpc trees

Hi all,

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

  arch/powerpc/platforms/Kconfig.cputype

between commit:

  8adddf349fda ("powerpc/mm/radix: Make Radix require HUGETLB_PAGE")

from the powerpc-fixes tree and commits:

  1bb2bae2e6c7 ("powerpc/mm/radix: Use KUEP API for Radix MMU")
  890274c2dc4c ("powerpc/64s: Implement KUAP for Radix MMU")

from the powerpc tree and commits:

  80d5ae3cf456 ("mm: simplify MEMORY_ISOLATION && COMPACTION || CMA into CONTIG_ALLOC")
  3653abf7cded ("hugetlb: allow to free gigantic pages regardless of the configuration")

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.
