Kees Cook - May 24, 2011, 9:04 p.m.
The following changes since commit 1e9ed812fef72843c4cbd4a1dd5c248aff332184:

  UBUNTU: Ubuntu-2.6.39-3.9 (2011-05-20 09:53:38 +0100)

are available in the git repository at:
  git://kernel.ubuntu.com/kees/ubuntu-oneiric.git master

Ingo Molnar (2):
      UBUNTU: ubuntu: nx-emu - i386: NX emulation
      UBUNTU: ubuntu: nx-emu - i386: mmap randomization for executable mappings

Kees Cook (8):
      Revert "UBUNTU: SAUCE: nx-emu: further clarify dmesg reporting"
      Revert "nx-emu: fix inverted report of disable_nx"
      Revert "UBUNTU: SAUCE: nx-emu: use upstream ASLR when possible"
      Revert "exec-randomization: brk away from exec rand area"
      Revert "mmap randomization for executable mappings on 32-bit"
      Revert "nx-emu: standardize boottime message prefix"
      Revert "nx-emu: drop exec-shield sysctl, merge with disable_nx"
      Revert "i386: NX emulation"

 mm/mmap.c                 |    6 +++---
 2 files changed, 6 insertions(+), 6 deletions(-)

(The above delta between reverts and commits are comment clean-ups and one
minor code position change for general clarification. Also, I made Ingo the
author, since the bulk of the code is his work. Hopefully this won't
complicate the delta review too badly.)

Thanks!

Applied to Oneiric master-next.

Thanks,

Leann - I think you should just rebase the reverts out of existence 
since they don't really have any historical relevance for Oneiric, 
especially now that we'll never rebase against Natty again.

I was actually going to drop them when we rebased to 2.6.40-rc1.  But
I'm cool to do it now too.  I'll push in a bit.
