KOSAKI Motohiro 4b6ddbf7ed pagewalk: fix walk_page_range() don't check find_vma() result properly 
The doc of find_vma() says,

    /* Look up the first VMA which satisfies  addr < vm_end,  NULL if none. */
    struct vm_area_struct *find_vma(struct mm_struct *mm, unsigned long addr)
    {
     (snip)

Thus, caller should confirm whether the returned vma matches a desired one.
