I don't recall exactly but it probably was 4k remapping everything into vmalloc area and didn't need large contiguous area. The problem with the former approach was that it added a lot of extra TLB pressure. The current allocator avoids that by overlaying the static percpu areas onto the linear address space which requires punching holes in an contiguous area.
