Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc_ppc64_defconfig)
failed like this:

mm/mmap.c: In function 'SYSC_mmap_pgoff':
mm/mmap.c:1271:15: error: 'MAP_HUGE_SHIFT' undeclared (first use in this function)
mm/mmap.c:1271:15: note: each undeclared identifier is reported only once for each function it appears in
mm/mmap.c:1271:33: error: 'MAP_HUGE_MASK' undeclared (first use in this function)

Caused by commit 160b36937ca2 ("mm: support more pagesizes for
MAP_HUGETLB/SHM_HUGETLB").

I have reverted that commit for today (along with the two fix patches).
