commit 33130d00dc1422c5a3071d771b90dafd77e22643

    Fix segfault in relocate_erratum_stub on aarch64.

    The fix for PR21868 (an internal error when --fix-cortex-a53-843419
    is applied) has a small mistake in it. When the stub_owner section
    needs an erratum fix an incorrect address for the stubs for the section
    is given to relocate_erratum_stub. If we are lucky we will get a segfault;
    if we aren't, an incorrect patch or data corruption is possible.
    The error is visible in PR21868, but the side-effects aren't fatal.

    gold/
        PR gold/22233
        * aarch64.cc (AArch64_relobj::fix_errata_and_relocate_erratum_stubs):
        Fix calculation of stub address.
