Got it, sorry for the misunderstanding. I really appreciate your
reviewing, great comments and suggestions. Glad to see that now we
don't hesitate to shrink kernel modules area to 1G after discussion. I
will ping Ingo to ask if he has any suggestion since he has been taking
care of the KERNEL_IMAGE_SIZE value changing.
