From 653df36bbe58e20258610bc74c5940c456b31084 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Sat, 1 Jan 2011 21:50:34 +0100 Subject: 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.
