    mmap04.c: Avoid vma merging
    
    We hit a scenario where new mapping was merged with existing mapping of
    same permission and the return address from the mmap was hidden in the
    merged mapping in /proc/self/maps, causing the test to fail.
    To avoid this, we first  create a 2-page mapping with the different
    permissions, and then remap the 2nd page with the perms being tested.

Title:
  mmap04 from ubuntu_ltp_syscalls failed with T-lts

Status in ubuntu-kernel-tests:
  New

Bug description:
  This issue pops up after updating to the latest tip of LTP test suite
  (commit 776b57984 "rwtest: Remove df symlink check")

  I think the failure is because of the API and test case change in
  https://github.com/linux-test-
  project/ltp/commit/dd7b485850d28fd5a0b54662f8f7958e677f6a0c

  It's only failing with T-lts (4.4.0-248.282~14.04.1), passed with
  Xenial and newer kernels.
