Hi Joey,

Should I just lock down sys_bpf() entirely for now?  We can always free it up
somewhat later.

OK~~ Please just remove my patch until we find out a way to
verify bpf code or protect sensitive data in memory.

I think that we don't need to lock down sys_bpf() now because
we didn't lock down other interfaces for reading arbitrary
address like /dev/mem and /dev/kmem.

Thanks a lot!
