We have almost the same code for mtrr cleanup and amd_bus checkup, and this code will also be used in replacing bootmem with early_res, so try to move them together and reuse it from different parts. Also rename update_range to subtract_range as that is what the function is actually doing. -v2: update comments as Christoph requested Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <1265793639-15071-4-git-send-email-yinghai@kernel.org> Signed-off-by: H.
