Cyrill Gorcunov 46661cf8b2 vdso: make -- Export VDSO and CONFIG_VDSO 
We will need it to figure out if architecture
needs vDSO handling code to be built. Note
currently only x86 is exporting vDSO simply
because ARM support is not yet ready.

README 

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
