    [PATCH] Increase SECTION_MAP_LAST_BIT to 5

    * Required for kernel 5.12

    Kernel commit 1f90a3477df3 ("mm: teach pfn_to_online_page() about
    ZONE_DEVICE section collisions") added a section flag
    (SECTION_TAINT_ZONE_DEVICE) and causes makedumpfile an error on
    some machines like this:

      __vtop4_x86_64: Can't get a valid pmd_pte.
      readmem: Can't convert a virtual address(ffffe2bdc2000000) to physical address.
      readmem: type_addr: 0, addr:ffffe2bdc2000000, size:32768
      __exclude_unnecessary_pages: Can't read the buffer of struct page.
      create_2nd_bitmap: Can't exclude unnecessary pages.

    Increase SECTION_MAP_LAST_BIT to 5 to fix this.  The bit had not
    been used until the change, so we can just increase the value.
