Hi all-

Known issues:
 - tcp md5, virtio_net, and virtio_console will have issues.  Eric Dumazet
   has a patch for tcp md5, and Michael Tsirkin says he'll fix virtio_net
   and virtio_console.

 How about PTRACE_SETREGS, it's using the child stack's vmapped address to put regs?

--Mika

PTRACE_SETREGS is ok of course.
