All of them are done through builtin functions: platform initialization, EEH device creation, and EEH subsystem enablement. All of them are done no later than ppc_md.setup_arch. That means that the slab/slub isn't ready yet, so we have to allocate memory chunks on basis of PAGE_SIZE for those dynamically created EEH devices. That's pretty expensive. In order to utilize slab/slub for memory allocation, we have to move the EEH initialization functions around, but all of them should be called after slab is ready.
