Raw Normal View History

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!

[SPARC64]: Move DCACHE_ALIASING_POSSIBLE define to asm/page.h This showed that arch/sparc64/kernel/ptrace.c was not getting the define properly, and thus the code protected by this ifdef was never actually compiled before. So fix that too. Signed-off-by: David S. Miller <davem@davemloft.net>
