From c9b9ed0fdbf90a7a7e3c111c6a99b5f42f78a6a7 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Sat, 1 Jan 2011 21:50:34 +0100 Subject: [PATCH] qcow2: fix unaligned access cpu_to_be64w() is called with an obviously non-aligned pointer. Use cpu_to_be64wu() instead. It fixes unaligned accesses errors on IA64 hosts.
