    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.
