[PATCH] Correct printk %pF to work on all architectures

[Benjamin Herrenschmidt]

> Make dereference_function_descriptor() more accommodating by allowing
> architecture overrides.  I put the three overrides (for parisc64, ppc64
> and ia64) in arch/kernel/module.c because that's where the kernel
> internal linker which knows how to deal with function descriptors sits.
