Date: Mon, 19 Mar 2012 15:54:34 +0000 Message-ID: <1332172474-17567-1-git-send-email-anthony.perard@citrix.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+gceq-qemu-devel=gmane.org@nongnu.org Sender: qemu-devel-bounces+gceq-qemu-devel=gmane.org@nongnu.org To: QEMU-devel , qemu-trivial@nongnu.org Cc: Anthony PERARD , Anthony Liguori , Xen Devel , Avi Kivity , Stefano Stabellini List-Id: xen-devel@lists.xenproject.org In cpu_physical_memory_rw, a change has been introduced and qemu_get_ram_ptr is no longuer called with the ram addr we want to access, but only with the section address. This patch fixes this. (All other call to qemu_get_ram_ptr are already called with the right address.) This patch fixes Xen guest.
