[CRIU] [PATCH 0/6] cpuinfo: Introduce dump and validation of CPU features

[Cyrill Gorcunov]

It's been noted that when we migrate tasks from one machine
to another we might have destination cpu less capable than
source one. For this sake we

 - add cpuinfo image on dump, which carries all cpu feature
   bits we're interested in one place

 - validate this image on restore to make sure we can proceed
   without errors

Please take a look.

Cyrill Gorcunov (6):
  cpuinfo: x86 -- Add protobuf entry
  cpuinfo: Prepare protobuf and magic
  cpuinfo: x86 -- Add needed bits and abbreviatures
  cpuinfo: x86 -- Add local copy of CpuinfoEntry
  cpuinfo: x86 -- Rework cpuinfo parsing
  cpuinfo: x86 -- Add dump and validation
