  leaking_addresses: add 32-bit support (2018-01-31 08:18:51 +1100)

----------------------------------------------------------------
leaking_addresses patches for 4.16-rc1

Here is the patch set for changes to scripts/leaking_addresses.pl for
the 4.16-rc1 merge window.  The first 4 patches are clean up.  Then we
add the following functionality:

  - check addresses against the vsyscall memory range instead of just
    the first and last address (x86_64)
  - add support for getting config options from the kernel config file
  - add support for 5 page table levels (x86_64)
  - add support for scanning 32 bit kernels (based on the page offset)

Along the way we add some helper sub routines and use `uname -m` instead
of Perl for doing architecture detection.  All these patches, except the
trivial clean up ones, were posted to LKML.  The script with this set
applied has been tested on x86_64 (kernel 4.4 and 4.15), ppc64 (kernel
4.4) and ARM 32-bit (kernel 4.9).
