Ho hum, that's the second iteration and it broke the build first time
too.

__raw_spin_lock_irqsave() definitions don't exist anywhere in the
tree, I wonder what this was even build tested against?

I'm reverting, and I'll be hard pressed to add new versions without
solid proof that it doesn't break the build a third time :-)
