-Subject: [PATCH] x86-64: Enable Intel CET
-
-Intel Control-flow Enforcement Technology (CET):
-
-https://en.wikipedia.org/wiki/Control-flow_integrity#Intel_Control-flow_Enforcement_Technology
-
-requires that on Linux, all linker input files are marked as CET enabled
-in .note.gnu.property section.  For high-level language source codes,
-.note.gnu.property section is added by compiler with the -fcf-protection
-option.  For assembly sources, include <cet.h> to add .note.gnu.property
-section.
