Well, the current direction is about as far away from that as you can
get, unless we basically call those system calls from inside our new
sys_restart() one.  As of now, we're as much work in the kernel as
possible, and doing the bare minimum in userspace.  That's what both
Oren and our OpenVZ colleagues have advocated.
