[CRIU] [PATCH 0/3] vdso proxy, v3

[Cyrill Gorcunov]

Hi guys, here is vdso proxy series. The main change from
previous series are

 - runtime vdso is not longer copied but rather remapped at
   new place

 - parasite now can detect the new runtime vdso on dumping and
   skip it from writting to image

Please take a look, thanks! At moment I'm thinking on how to
test it automatically with zdtm help...

  vdso: Introduce vdso engine
  vdso: Proxify vDSO code on restore
  dump: Escape double dumping of mangled vDSO
