    Yes please. And just to note it somewhere: landing the KCFI
    implementation on Clang depends on this series being accepted (i.e. if
    the arm64 and x86 maintainers are happy with this series, then that'll
    unblock landing it in Clang (no reason to land something that won't get
    used.)
