Again this is exactly what I argued back in 2000. I have long held
that the kernel link order is over defined where it should be fuzzy.
Defining an order between groups but not within groups is exactly what
I wanted but I was told that the initialization order must be
explicitly and fully specified for the entire kernel. Nice to see that
I have been proved right, pity it took this long. C'est la vie.

The Makefiles still control order within the .text.init section
(__init, module_init). Many drivers depend on the Makefile getting
that order correct, otherwise probes stuff up. But which entries are
order sensitive and which ones are from a developer picking a random
place to insert obj-$(CONFIG) is anyone's guess.
