From 65b4ee62c9cd10640f0054f47fd84c7920e8c118 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Wed, 6 Aug 2014 16:09:57 -0700 Subject: lib: bitmap: remove unnecessary mask from bitmap_complement Since the extra bits are "don't care", there is no reason to mask the last word to the used bits when complementing. This shaves off yet a few bytes.
