When SPARSEMEM_EXTREME is enabled, memory_present() wants to use bootmem
to allocate data structures. However, we call memory_present() after
declaring memory to bootmem, but before we've reserved areas.
This leads to sparsemem data structures being overwritten later in the
kernel's initialization (when slab initializes.)
