The patch can work for zone contains NOMAP regions.

However, if BIOS do not add WB/WT/WC attribute to a physical address range, the
is_memory(md) will return false and this range will not be added to memblock.
efi_init
-> reserve_regions
if (is_memory(md)) {
early_init_dt_add_memory_arch(paddr, size);

if (!is_usable_memory(md))
memblock_mark_nomap(paddr, size);
}

Then BUG_ON() check will also fails. Any idea about it?

Here is the crash log I got from D05:
