the above build error came from a bisection run, the fix i sent was for
this build error:

mm/hugetlb.c: In function âhugetlb_acct_memory': mm/hugetlb.c:1507:
error: implicit declaration of function âcpuset_mems_nr'

but i also get a second hugetlb build failure on 64-bit x86:

arch/x86/mm/built-in.o: In function `setup_hugepagesz':
hugetlbpage.c:(.init.text+0xb49): undefined reference to `hugetlb_add_hstate'

fixed by the patch below.
