    mesa: add support for CET to x86/x86-64 asm files. · abfcc11e
    Dave Airlie authored
    Control-flow enforcement technology is a new instructions on x86
    processors to denote where indirect jumps can land. Gcc auto adds
    the instruction (which encodes as a NOP on older CPUs) to entrypoints
    but assembler files need manual adding. This adds it to all the
    entry points in the mesa x86/x86-64 assembler files.
    
    This will only happen if mesa is built with the -fcf-protection flag
    to gcc as some distros are wanting to do.
