Let's not piggy-back on the existing lock and use a separate lock for the huge page list. Now that we use a separate lock, there is no need to disable interrupts, so use the non-irqsave variants. We only required the irqsave variants because of the balloon device lock. This is a preparation for changing the locking used to protect balloon_dev_info. While at it, talk about "page migration" instead of "page compaction". We'll change that in core code soon as well.
