From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- arch/mips/include/asm/cpu-info.h | 94 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 94 insertions(+) create mode 100644 arch/mips/include/asm/cpu-info.h (limited to 'arch/mips/include/asm/cpu-info.h') diff --git a/arch/mips/include/asm/cpu-info.h b/arch/mips/include/asm/cpu-info.h new file mode 100644 index 00000000..c454550e --- /dev/null +++ b/arch/mips/include/asm/cpu-info.h @@ -0,0 +1,94 @@ +/* + * This file is subject to the terms and conditions of the GNU General Public + * License.
