Cyrill Gorcunov de770e023a cpuinfo: x86 -- Rework cpuinfo features fetching 
Instead of parsing procfs lets use native cpuid(), it's a way faster.
The dark side is that the kernel may disable some of features via
bootline options even if they are present on hardware but for us
it's fine -- we will be testing hardware cpu for features anyway.

The X86_FEATURE_ bits are gathered from two sources: linux kernel
and cpu specifications.

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
