Hmm, are they really just paired? The description in arch/sparc64/mm/extable.c
looked differently to me. Anyways - given all these complexities
doing the sort in arch code is probably better. It wasn't my idea anyways
to move it into generic code ;-) 

It's probably not very critical for the other architectures anyways
because they likely don't depend on exception tables working in __init
functions (and if they do they likely already have an own sort function)
