+commit 88bfbf90e35f1213f9967a97dee0b2039f9998a4

+    tools/libxc/xc_dom_arm: add missing variable initialization
+    
+    The variable domctl.u.address_size.size may remain uninitialized if
+    guest_type is not one of xen-3.0-aarch64 or xen-3.0-armv7l. And the
+    code precisely checks if this variable is still 0 to decide if the
+    guest type is supported or not.
+    
+    This fixes the following build failure with gcc 7.x:
+    
+    xc_dom_arm.c:229:31: error: 'domctl.u.address_size.size' may be used uninitialized in this function [-Werror=maybe-uninitialized]
+         if ( domctl.u.address_size.size == 0 )
+    
+    Patch originally taken from
+    https://www.mail-archive.com/xen-devel@lists.xen.org/msg109313.html.
