rcu: use irq-safe locks
Some earlier tip/core/rcu patches caused RCU to incorrectly enable irqs
too early in boot. This caused Yinghai's repeated-kexec testing to
hit oopses, presumably due to so that device interrupts left over from
the prior kernel instance (which would oops the newly booting kernel
before it got a chance to reset said devices). This patch therefore
converts all the local_irq_disable()s in rcuclassic.c to local_irq_save().
Besides, I never did like local_irq_disable() anyway. ;-)
