Intel has published Control-flow Enforcement (CET) in the Architecture
Instruction Set Extensions Programming Reference:

  https://software.intel.com/en-us/download/intel-architecture-instruction-set-
  extensions-programming-reference

The previous version (v7) of CET Shadow Stack patches is here:

  https://lkml.org/lkml/2019/6/6/1003

Summary of changes from v7:

  Rewrite ELF GNU property parsing (Patch #22).  Look at PT_GNU_PROPERTY now.
  Rebase to v5.3-rc4.
  Small fixes in response to comments.
