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!

+ CMTP (CAPI Message Transport Protocol) is a transport layer
+ for CAPI messages. CMTP is required for the Bluetooth Common
+ ISDN Access Profile.
+
+ Say Y here to compile CMTP support into the kernel or say M to
+ compile it as module (cmtp).
