Subject: linux-next: build failure after merge of the akpm-current tree

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

In file included from mm/shmem.c:61:0:
include/linux/swapops.h: In function 'is_swap_pte':
include/linux/swapops.h:57:2: error: implicit declaration of function 'pte_present_nonuma' [-Werror=implicit-function-declaration]

And a couple more similar.

Caused by commit 851fe3337768 ("x86: define _PAGE_NUMA by reusing
software bits on the PMD and PTE levels").

I have reverted this commit (and 7cb1c1eb682e "x86: define _PAGE_NUMA by
reusing software bits on the PMD and PTE levels -fix") for today and
wonder how many other architectures would be broken by this?  Everything
else with CONFIG_MMU set?
