Bug description:
  This was reported in bug 1630000
  I think it's better it tear it down into pieces.

  From the error message, it looks like this test should be skipped on
  Trusty 3.13 kernel:

  dev/mem unreadable for kernel memory ... (using 0x4fab5a72c0)
  (skipped: only 3.16 and later for ARM64) (exit code 7) FAIL

   FAIL: test_072_strict_devmem (__main__.KernelSecurityTest)
