Title:
  Xenial 32-bit: multipath exits with SIGSEGV

Status in multipath-tools package in Ubuntu:
  Fix Released
Status in multipath-tools source package in Xenial:
  Fix Released
Status in multipath-tools source package in Yakkety:
  Fix Committed

Bug description:
  [Impact]

   * The CLI for multipath segfaults when on 32-bit platforms.

   * As example, a simple 'sudo multipathd -k"show paths"' will blow up,
     assuming you have a multipath configured.  

   * The ultimate cause of the bug is the codebase not correctly dealing
  with bit flags that have exceeded the 32-bit natural word size on
  32-bit architectures.  The fix has been cherrypicked from upstream.

  
  [Test Case]

   * You'll need to setup a 32-bit (e.g. i386) multipath environment to
  test.  I used qemu/kvm.

   * See https://bugs.launchpad.net/ubuntu/+source/multipath-
  tools/+bug/1611360/comments/4

   * Once configured, type "sudo multipathd -k"show paths" and it will
  fail with a segfault on 32-bit architectures, but succeed on 64-bit architectures.  

  
  [Regression Potential] 

   * Limited potential as only affects flag bits > 32-bits.  In addition
  to testing commands affected by these bits on 32-bit platform (i386),
  I've regression tested that these commands work on 64-bit platform
  (amd64).
