I am getting the following compilation error with sparc32
allmodconfig. I didn't check more closely yet.

mm/hmm.c: In function 'hmm_vma_walk_pmd':
mm/hmm.c:370:53: error: macro "pte_index" requires 2 arguments, but only 1 given
    unsigned long pfn = pmd_pfn(pmd) + pte_index(addr);

    unsigned long pfn = pmd_pfn(pmd) + pte_index(addr);
                                       ^
mm/hmm.c:370:39: note: each undeclared identifier is reported only once for each function it appears in
