Ying Huang,
I removed page_is_reserved_early....it cause init highmem take extra time on my big box.
please check efi_reserve_early that is calling reserve_early. so need to make sure "EFI memmap" is reserved in itself...otherwise you may need to update e820 table by add_memory_region (...., E820_RESERVED)...
