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

Hi Andrew,

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

  arch/powerpc/include/asm/pgtable.h

between commit:

  ee4889c7bc2a ("powerpc/mm: Don't have generic headers introduce functions touching pte bits")

from the powerpc tree and commit:

  e0e8474c0d55 ("mm, dax, gpu: convert vm_insert_mixed to pfn_t")

from the akpm-current tree.

I fixed it up (the code being changed was moved from this file - I added
the fix up patch below) and can carry the fix as necessary (no action
is required).
