The current debug print in EFI does
[ 0.000000] efi: mem84: type=3, attr=0xf, range=[0x00000000645b5000-0x00000000645fb000) (0MB)
and rounds off the size to 0MB and isn't very useful. We should print this in
Kib. After applying this patch we get better info with
[ 0.000000] efi: mem84: type=3, attr=0xf, range=[0x00000000645b5000-0x00000000645fb000) (280kiB)
