-Subject: [PATCH] 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.
