You cannot solve your 4k issues without getting the zerobased stuff in becaus otherwise the large pointer arrays in the core (page allocator and slab allocator etc) are not removable. Without getting zerobased sorted out you will produce a lot of hacks around subsystems that create pointer arrays that would go away easily if you had the percpu aallocator. I'd say getting the zero based stuff issues fixed is a prerequisie for further work on 4k making sense. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
