Mmm. But if we're both putting hooks in the same places...

The CPU save and restore, yes. But I use a different format for recording the image metadata (I use bitmaps to record the locations of pages). Perhaps I should hasten to mention the bitmaps are discontiguous - single pages connected by a kmalloc'd list. The copyback itself will need to stay distinct.
