From a4d784eeab964a9cdb8e453ae98a14520ce13919 Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Sun, 25 Jan 2015 21:08:42 -0600 Subject: include/types.h: Provide BIT() macro This macro is controversial for arches where the bits are numbered MSb first, though we don't support such an arch. We've seen this macro creep into our tree in different places, so provide it in one place.
