From 6d7e925b88cd8436b1284158876580ea431cb954 Mon Sep 17 00:00:00 2001 From: Ionut Nicu Date: Sun, 21 Nov 2010 10:46:22 +0000 Subject: [PATCH] staging: tidspbridge: remove gb bitmap implementation Now that all users of gb have been converted to the standard linux bitmap API, we can remove it from the gen library.
