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! --- include/asm-sh/a.out.h | 26 ++ include/asm-sh/adc.h | 13 + include/asm-sh/addrspace.h | 38 ++ include/asm-sh/adx/io.h | 86 +++++ include/asm-sh/atomic.h | 114 ++++++
