Hi Andrew,

After merging the akpm-current tree, today's linux-next build (i386
defconfig) failed like this:

fs/hugetlbfs/inode.c: In function 'hugetlbfs_fallocate':
fs/hugetlbfs/inode.c:578:13: error: 'struct vm_area_struct' has no member named 'vm_policy'
   pseudo_vma.vm_policy =
             ^
fs/hugetlbfs/inode.c:579:4: error: implicit declaration of function 'mpol_shared_policy_lookup' [-Werror=implicit-function-declaration]
    mpol_shared_policy_lookup(&HUGETLBFS_I(inode)->policy,
    ^
fs/hugetlbfs/inode.c:595:28: error: 'struct vm_area_struct' has no member named 'vm_policy'
    mpol_cond_put(pseudo_vma.vm_policy);
                            ^
fs/hugetlbfs/inode.c:601:27: error: 'struct vm_area_struct' has no member named 'vm_policy'

                           ^
Caused by commit

  6b2ac4455b3d ("hugetlbfs: add hugetlbfs_fallocate()")

vm_policy and mpol_shared_policy_lookup are only defined when CONFIG_NUMA
is set.

I have reverted that commit for today.
