Subject: [PATCH] x86: Add NT_X86_CET note
Define NT_X86_CET which is the proposed note for CET state to support
Intel CET in Linux kernel. Will double check it after Intel CET patches
have been merged into Linux kernel.
binutils/
* readelf.c (get_note_type): Support NT_X86_CET.
include/
* elf/common.h (NT_X86_CET): New.
