I will fix on v3 if agree with me this one.

There will be a redundancy always. You told me earlier of this patch it is for performance,
however my patch makes consistent by replacing the upper context check to checking work bit.
We can't do anything about audit_syscall_entry() because it is used in multiple places.

Is there a problem if we just replace the upper context check with work bit as i did in this patch.
