Title:
  Kernel security test test_022_aslr_hardy_vdso failed on Precise i386

Status in linux package in Ubuntu:
  Triaged

Bug description:
  This issue can be reproduced in 3.2.0-133 in proposed and 3.2.0-131.
  So it should not be considered as a regression.

  We didn't spot this issue before, until I'm testing 3.2 kernel on one
  of the laptop (CID 201307-13930) in Cert lab instead of using our
  regular regression-testing test pool from kernel team this cycle.
