From 8167c1f071426706c233e93ecfd13aba7d5c06c8 Mon Sep 17 00:00:00 2001 From: Rosen Penev Date: Sun, 27 Sep 2026 13:35:01 -0700 Subject: tty: serial: mpc52xx_uart: move static declarations up. Avoid a compilation error so that they're not used before being declared. Fixes: 4d105880666a ("tty: serial: mpc52xx_uart: add bounds check for psc_num array index") Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202609260356.tJWbd1WU-lkp@intel.com/ Signed-off-by: Rosen Penev Link: https://patch.msgid.link/20260927203501.14105-1-rosenp@gmail.com Signed-off-by: Greg Kroah-Hartman --- include/xen/interface/features.h | 102 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 102 insertions(+) create mode 100644 include/xen/interface/features.h (limited to 'include/xen/interface/features.h') diff --git a/include/xen/interface/features.h b/include/xen/interface/features.h new file mode 100644 index 000000000..53f760378 --- /dev/null +++ b/include/xen/interface/features.h @@ -0,0 +1,102 @@ +/* SPDX-License-Identifier: MIT */ +/****************************************************************************** + * features.h + * + * Feature flags, reported by XENVER_get_features. + * + * Copyright (c) 2006, Keir Fraser + */ + +#ifndef __XEN_PUBLIC_FEATURES_H__ +#define __XEN_PUBLIC_FEATURES_H__ + +/* + * If set, the guest does not need to write-protect its pagetables, and can + * update them via direct writes. + */ +#define XENFEAT_writable_page_tables 0 + +/* + * If set, the guest does not need to write-protect its segment descriptor + * tables, and can update them via direct writes. + */ +#define XENFEAT_writable_descriptor_tables 1 + +/* + * If set, translation between the guest's 'pseudo-physical' address space + * and the host's machine address space are handled by the hypervisor.
