Title:
  move_pages04 from ubuntu_ltp_syscalls starts to fail (properly) on
  O/N/J/F/B/X

Status in ubuntu-kernel-tests:
  New

Bug description:
  Upstream LTP has fixed move_pages04 [1], and the commits are already
  included in sru/sru-xenial as of today. Therefore, move_pages04 should
  start to fail on all older kernels except Plucky, unless an unlikely
  tricky backport happens in the future. This bug is opened for hinting
  it.

  e0dfe8e8ccbb move_pages04: check for "invalid area", "no page mapped" and "shared zero page mapped"

  7685390eb18f move_pages04: convert to new test API
