    x86: Add NT_X86_CET note
    
    Define NT_X86_CET which is the proposed note for x86 CET state to support
    Intel CET in Linux kernel.  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.
