    [PATCH] Avoid false-positive mem_section validation with vmlinux

    Currently get_mem_section() validates if SYMBOL(mem_section) is the address
    of the mem_section array first.  But there was a report that the first
    validation wrongly returned TRUE with -x vmlinux and SPARSEMEM_EXTREME
    (4.15+) on s390x.  This leads to crash failing statup with the following
    seek error:

      crash: seek error: kernel virtual address: 67fffc2800  type: "memory section root table"

    Skip the first validation when satisfying the conditions.
