    mm, page_vma_mapped: Drop faulty pointer arithmetics in check_pte()
    
    Tetsuo reported random crashes under memory pressure on 32-bit x86
    system and tracked down to change that introduced
    page_vma_mapped_walk().
    
    The root cause of the issue is the faulty pointer math in check_pte().
    As ->pte may point to an arbitrary page we have to check that they are
    belong to the section before doing math. Otherwise it may lead to weird
    results.
    
    It wasn't noticed until now as mem_map[] is virtually contiguous on
    flatmem or vmemmap sparsemem. Pointer arithmetic just works against all
    'struct page' pointers. But with classic sparsemem, it doesn't because
    each section memap is allocated separately and so consecutive pfns
    crossing two sections might have struct pages at completely unrelated
    addresses.
    
    Let's restructure code a bit and replace pointer arithmetic with
    operations on pfns.
