[PATCH v2 6/7] xen/x86: Replace GPL v2.0+ license boilerplate with an SPDX tag in *.c



From: Julien Grall <jgrall@xxxxxxxxxx>

It is easier to understand the license of a file when using SPDX.

This is replacing the below pattern with the SPDX tag GPL-2.0-or-later
in xen/arch/x86/*.c:

 * This program is free software; you can redistribute it and/or modify
 * it under the terms of the GNU General Public License as published by
 * the Free Software Foundation; either version 2 of the License, or
 * (at your option) any later version.
 *

 * but WITHOUT ANY WARRANTY; without even the implied warranty of
 * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 * GNU General Public License for more details.
 *
 * You should have received a copy of the GNU General Public License
 * along with this program; If not, see <http://www.gnu.org/licenses/>.

Signed-off-by: Julien Grall <jgrall@xxxxxxxxxx>

---
    Changes in v2:
        - The license is GPLv2.0+ rather than GPLv2.0
