Subject[PATCH] initramfs + sysfs as root fix
Date
This is my first real patch, so please vet thoroughly

This patch allows a person to not require mounting a root device at startup.
This works idealy for people trying to use the initramfs/sysfs as the only
filesystem.

What happens is that when the root device is set to 0,0 mount_root is not
called. I have tested in VMWare extensively, and the patch is quite minimal.

Please let me know if I should send this somewhere else as well.

Also, please be adviased that I did not dream up the goto - I am just keeping
in line with the existing file structure.
