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)...
