    26	 * This function takes care of figuring out which function to use to
    27	 * map the EFI memory map in efi.memmap based on how far into the boot
    28	 * we are.
    29	 *
    30	 * During bootup EFI_MEMMAP_LATE in data->flags should be clear since we
    31	 * only have access to the early_memremap*() functions as the vmalloc
    32	 * space isn't setup.  Once the kernel is fully booted we can fallback
    33	 * to the more robust memremap*() API.
    34	 *
    35	 * Returns zero on success, a negative error code on failure.
