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]

fs/hugetlbfs/inode.c:595:28: error: 'struct vm_area_struct' has no member named '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.
