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

Hi all,

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

  arch/powerpc/Kconfig

between commit:

  c6b05f4e233c ("powerpc/kconfig: Restore alphabetic order of the selects under CONFIG_PPC")

from the powerpc tree and commits:

  fd7d5c273c43 ("mm: generalize HUGETLB_PAGE_SIZE_VARIABLE")
  301ba77ae03c ("mm: generalize ARCH_ENABLE_MEMORY_[HOTPLUG|HOTREMOVE]")

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.
