this patch is modeled after 3.14's linux-vserver patch where vshelper is
patched in between uevent_helper and sg-big-buff entires in kern_table[].
sorry for the delay, but i had to work out the initrd error about no
permission to write to /sys/kernel/uevent_helper (ie wheezy's udev still
requires CONFIG_UEVENT_HELPER=y, though turned-off in debian's 3.18 config in
experimental).
