Linux-2.6.12-rc2v2.6.12-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!

The DRM provides synchronized access to the graphics hardware via + the use of an optimized two-tiered lock. + + 2. The DRM enforces the DRI security policy for access to the graphics + hardware by only allowing authenticated X11 clients access to + restricted regions of memory. + + 3. The DRM provides a generic DMA engine, complete with multiple + queues and the ability to detect the need for an OpenGL context + switch. + + 4.
