    Subject[PATCH v2 12/48] kcsan: clang: retire CONFIG_KCSAN_KCOV_BROKEN
    From
    kcov used to be broken prior to Clang 11, but right now that version is
    already the minimum required to build with KCSAN, because no prior
    compiler has "-tsan-distinguish-volatile=1".

    Therefore KCSAN_KCOV_BROKEN is not needed anymore.
