Thats another area where we would need some cleanup in the future. The
slab_is_available() has become a check for the end of the use of bootmem.

What would be clearer is to have something like

allocator_bootstrap_complete()

to tell us that all memory allocators are available (slab, page, percpu,
vmalloc);
