    all arch: remove system call sys_sysctl · 88db0aa2
    Xiaoming Ni authored
    Since commit 61a47c1a ("sysctl: Remove the sysctl system call"),
    sys_sysctl is actually unavailable: any input can only return an error.
    
    We have been warning about people using the sysctl system call for years
    and believe there are no more users.  Even if there are users of this
    interface if they have not complained or fixed their code by now they
    probably are not going to, so there is no point in warning them any
    longer.
    
    So completely remove sys_sysctl on all architectures.
