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! --- .../asm-mips/mach-generic/cpu-feature-overrides.h | 13 ++ include/asm-mips/mach-generic/floppy.h | 139 +++++++++++++++++++++ include/asm-mips/mach-generic/ide.h | 119 ++++++++++++++++++ include/asm-mips/mach-generic/irq.h | 13 ++ include/asm-mips/mach-generic/mangle-port.h | 16 +++ include/asm-mips/mach-generic/mc146818rtc.h | 36 ++++++ include/asm-mips/mach-generic/param.h | 13 ++ include/asm-mips/mach-generic/spaces.h | 72 +++++++++++ include/asm-mips/mach-generic/timex.h | 22 ++++ include/asm-mips/mach-generic/topology.h | 1 + 10 files changed, 444 insertions(+) create mode 100644 include/asm-mips/mach-generic/cpu-feature-overrides.h create mode 100644 include/asm-mips/mach-generic/floppy.h create mode 100644 include/asm-mips/mach-generic/ide.h create mode 100644 include/asm-mips/mach-generic/irq.h create mode 100644 include/asm-mips/mach-generic/mangle-port.h create mode 100644 include/asm-mips/mach-generic/mc146818rtc.h create mode 100644 include/asm-mips/mach-generic/param.h create mode 100644 include/asm-mips/mach-generic/spaces.h create mode 100644 include/asm-mips/mach-generic/timex.h create mode 100644 include/asm-mips/mach-generic/topology.h (limited to 'include/asm-mips/mach-generic') diff --git a/include/asm-mips/mach-generic/cpu-feature-overrides.h b/include/asm-mips/mach-generic/cpu-feature-overrides.h new file mode 100644 index 000000000000..0aecfd08e39a --- /dev/null +++ b/include/asm-mips/mach-generic/cpu-feature-overrides.h @@ -0,0 +1,13 @@ +/* + * This file is subject to the terms and conditions of the GNU General Public + * License.
