[Devel] [PATCH 0/4] Compat C/R patches

[Dmitry Safonov]

  Those patches adds possibility to C/R compatible 32-bit application
with CRIU help. Tested with criu-dev branch with a couple of v3.10
specific patches (which are also good for v3.11, which CRIU supports),
I will sent them to criu shortly.
  3/4 first patches are backports of my upstream patches, which *arn't*
yet in vanilla, but lkml folks found them good [1].
The fourth patch is made from a scratch, as vDSO part of the kernel
has been changed from v3.10 quit greatly.

Now I'm working on upstream v3 version, any updates/API changes that
may happen, will be backported on top of this version.
Changes to v3 are to vdso part of patches set, which differs.

This patches set contains quite big changes, so please, review and
tell if you have some concerns.

Thanks,
             Dmitry
