Title:
  arm64 kernel has READ_IMPLIES_EXEC in personality, makes data areas
  executable

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  $ uname -p
  aarch64
  $ cat /proc/version_signature
  Ubuntu 3.13.0-63.103-generic 3.13.11-ckt25
  $ cat /proc/self/personality
  00400000

  include/uapi/linux/personality.h in the linux source tree defines
  "READ_IMPLIES_EXEC =     0x0400000,"

  A patch to start to address this was submitted upstream at
  https://lkml.org/lkml/2014/5/14/520 but did not get taken.

  This was noticed by the nx portiong of the qrt test-kernel-security
  tests on arm64 that indicate that the data sections are allowed to
  execute code.
