From 41f0624d559ef63f1f3c97f4d4ecb3e310935eb9 Mon Sep 17 00:00:00 2001 Message-Id: From: Blue Swirl Date: Sun, 22 Jan 2012 11:00:44 +0000 Subject: [PATCH 1/3] memory: fix dirty mask function length handling Fix handling of cases like start = 0xfff, length = 2. Change length to ram_addr_t to handle larger lengths.
