Cyrill Gorcunov 18fe357563 vdso: Implement vDSO proxification of any vvar/vdso order 
In latest linux-next the vdso zone is placed _after_ vvar
zone so eventually we need to handle any combination of
the following cases

 - no vvar zone
 - vvar before vdso
 - vvar after vdso

Here we address all them.

criu
====

An utility to checkpoint/restore tasks. Using this tool, you can
freeze a running application (or part of it) and checkpoint it to
a hard drive as a collection of files. You can then use the files
to restore and run the application from the point it was frozen
at. The distinctive feature of the CRIU project is that it is
mainly implemented in user space.

The project home is at http://criu.org

Pages worth starting with are
* Kernel configuration, compilation, etc: http://criu.org/Installation
* A simple example of usage: http://criu.org/Simple_loop
* More sophisticated example with graphical app: http://criu.org/VNC
