After discussion, it was decided that, because the addtional entry in
the features directory will cause apparmor on the next boot to recompile
all policy unnecessarily (because there won't be any actual policy
changes) which can be a problem for low power devices, this patch will
not be brought back to the 4.4.x kernel series.

Title:
  apparmor fs does not reflect 4.4 backport of mmap perms change

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:
  Won't Fix

Bug description:
  The upstream commit 9f834ec18defc369d73ccf9e87a2790bfa05bf46 was
  backported to the 4.4.x xenial kernel series to address
  CVE-2019-11190. However, the change introduces subtle changes to
  apparmor policy, including in the apparmor regression tests. A sysfs
  entry was added in later kernels to indicate this;
  34c426acb75cc21bdf84685e106db0c1a3565057 upstream; this should be
  backported to the 4.4 kernels.
