    sysctl: Remove the sysctl system call · 61a47c1a

    This system call has been deprecated almost since it was introduced, and
    in a survey of the linux distributions I can no longer find any of them
    that enable CONFIG_SYSCTL_SYSCALL.  The only indication that I can find
    that anyone might care is that a few of the defconfigs in the kernel
    enable CONFIG_SYSCTL_SYSCALL.  However this appears in only 31 of 414
    defconfigs in the kernel, so I suspect this symbols presence is simply
    because it is harmless to include rather than because it is necessary.
    
    As there appear to be no users of the sysctl system call, remove the
    code.  As this removes one of the few uses of the internal kernel mount
    of proc I hope this allows for even more simplifications of the proc
    filesystem.
