Hi Naoya,

[also build test ERROR on next-20160303]
[cannot apply to tip/x86/core asm-generic/master]
[if your patch is applied to the wrong git tree, please drop us a note to help improving the system]

url: https://github.com/0day-ci/linux/commits/Naoya-Horiguchi/mm-page-migration-enhancement-for-thp/20160303-154610

Note: the linux-review/Naoya-Horiguchi/mm-page-migration-enhancement-for-thp/20160303-154610 HEAD a0e4b096d1324d23aed454a230d4d31b99b92ae7 builds fine.
It only hurts bisectibility.

All errors (new ones prefixed by >>):

mm/mempolicy.c: In function 'new_node_page':
>> mm/mempolicy.c:1020:3: error: implicit declaration of function 'prep_transhuge_page' [-Werror=implicit-function-declaration]
prep_transhuge_page(thp);

cc1: some warnings being treated as errors

1015 thp = alloc_pages_node(node,
1016 (GFP_TRANSHUGE | __GFP_THISNODE) & ~__GFP_RECLAIM,

1018 if (!thp)
1019 return NULL;
