but on a single processor machine (i.e. #undef CONFIG_SMP) there is no
chance that there will be reads/writes from other processors so i dont
need any locking OR protection from interrupts.  so the degenerate case
of spin_lock_irqsave() isnt quite as dengerate as i would like for this
particular spin lock.
