Intel new CPU supports SMEP (Supervisor Mode Execution Protection). SMEP
prevents kernel from executing code in application. Updated Intel SDM describes
this CPU feature. The document will be published soon.

  x86, cpu: Add CPU flags for SMEP
  x86, cpu: Add SMEP CPU feature in CR4
  x86, cpu: Enable/disable SMEP
