From 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 16 Apr 2005 15:20:36 -0700 Subject: Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! --- arch/sh64/lib/iomap.c | 55 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 arch/sh64/lib/iomap.c (limited to 'arch/sh64/lib/iomap.c') diff --git a/arch/sh64/lib/iomap.c b/arch/sh64/lib/iomap.c new file mode 100644 index 000000000000..83c5f0c04958 --- /dev/null +++ b/arch/sh64/lib/iomap.c @@ -0,0 +1,55 @@ +/* + * arch/sh64/lib/iomap.c + * + * Generic sh64 iomap interface + * + * Copyright (C) 2004 Paul Mundt + * + * This file is subject to the terms and conditions of the GNU General Public + * License.
