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!

[PATCH] powerpc: Extends HCALL interface for InfiniBand usage This extends the HCALL interface for InfiniBand usage. I've made the patch against the linux-2.6 git tree and Segher's patch: [PATCH] Change H_StudlyCaps to H_SHOUTING_CAPS We moved this into the common powerpc code based on comments we got after posting the first eHCA InfiniBand device driver patch.
