[CRIU] [PATCH 04/15] cpuinfo: x86 -- Add local copy of CpuinfoEntry

[Cyrill Gorcunov]

We assume that all cpus in the system are same
family and stepping (it might be not true for
big systems but they are qute rare and not
guaranteed to work).

So we will use own local copy of protobuf entry
to fill it on startup and write into dump. On
restore we will need it to check caps with one
fetched from image file.
