[PATCH] memory hotplug prep: fixup bad_range()
When doing memory hotplug operations, the size of existing zones can obviously change. This means that zone->zone_{start_pfn,spanned_pages} can change. There are currently no locks that protect these structure members. However, they are rarely accessed at runtime. Outside of swsusp, the only place that I can find is bad_range(). So, split bad_range() up into two pieces: one that needs to be locked and anther that doesn't.
