Currently the slab allocators (ab)use the struct page 'lru' list_head. We have a list head for slab allocators to use, 'slab_list'. Clean up all three allocators by using the 'slab_list' list_head instead of overloading the 'lru' list_head. Initial patch makes no code changes, adds comments to #endif statements. Final 3 patches do changes as a patch per allocator, tested by building and booting (in Qemu) after configuring kernel to use appropriate allocator. Also build and boot with debug options enabled (for slab and slub). thanks, Tobin. Tobin C.
