Ok, added the appropriate kbuild people: Machal - skb_dev_set() no
longer exists, there are no users of it, so it looks like something
doesn't get rebuilt correctly.

Paweł, can you please also send us the config file you're using, then
we can recreate the exact setup you have.

This make results in

ERROR: "handle_edge_irq" [drivers/gpio/gpio-pch.ko] undefined!
ERROR: "irq_to_desc" [drivers/gpio/gpio-pch.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

The second failure is simply GIGO.
