2006-10-04Remove all inclusions of <linux/config.h>Dave Jones
kbuild explicitly includes this at build time. Signed-off-by: Dave Jones <davej@redhat.com>
2006-09-26[PATCH] annotate arch/x86_64/lib/*.SJan Beulich
Add unwind annotations to arch/x86_64/lib/*.S, and also use the macros provided by linux/linkage.h where-ever possible. Some of the alternative instructions handling needed to be adjusted so that the replacement code would also have valid unwind information.

2006-02-04[PATCH] x86_64: Undo the earlier changes to remove unrolled copy/memset ↵Andi Kleen
functions They cause quite bad performance regressions on Netburst This is temporary until we can get new optimized functions for these CPUs. This undoes changes that were done in 2.6.15 and in 2.6.16-rc1, essentially bringing the code back to 2.6.14 level. Only change is I renamed the X86_FEATURE_K8_C flag to X86_FEATURE_REP_GOOD and fixed the check for the flag and also fixed some comments.

2005-11-14[PATCH] x86_64: Remove optimization for B stepping AMD K8Andi Kleen
B stepping were the first shipping Opterons. memcpy/memset/copy_page/ clear_page had special optimized version for them. These are really old and in the minority now and the difference to the generic versions (using rep microcode) is not that big anyways. So just remove them.

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!
