This patch set is to rearrange event notifier for memory hotplug, because the old notifier has some defects. For example, there is no information like new memory's pfn and # of pages for callback functions. Fortunately, nothing uses this notifier so far, there is no impact by this change. (SLUB will use this after this patch set to make kmem_cache_node structure). In addition, descriptions of notifer is added to memory hotplug document. This patch was a part of patch set to make kmem_cache_node of SLUB to avoid panic of memory online. But, I think this change becomes not only for SLUB but also for others. So, I extracted this from it. This patch set is for 2.6.23-mm1. I tested this patch on my ia64 box. Please apply. Bye. -- Yasunori Goto
