[CRIU] [PATCH 0/5] vdso: Handle new vvar zone

[Cyrill Gorcunov]

Hi, here is a first attempt to handle new vDSO format
for checkpoint/restore. Please take a look. It survives
on both old and new (3.16-merge) kernels. But I would
appreciate additional testing.

Also I didn't yet tested migration, it's in process but
I suppose this should not be a blocker, if it fail I fix
it on top (after all current criu won't be working with
3.16 family so noone can migrate there yet ;)

Cyrill Gorcunov (5):
  vdso: image -- Add VMA_AREA_VVAR flag
  vdso: dump -- Don't dump contents of vvar zone
  vdso: util -- Show 'vvar' abreviature when meet VMA_AREA_VVAR
  vdso: parasite -- Prepare new vdso mark structure.
  vdso: x86 -- Add handling of vvar zones
