commit 5b0aa8b6425de10a6fdfe870a9fe517027a60dd9

    kernel: Add security.ptr_restrict sysctl.
    
    Allow to prevent leaking kernel addresses back to the userland
    (intentionally or not). We have quite a lot debug prints already and by
    default we allow unprivileged processes to read kernel message buffers.
