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!

+ * Description :
+ *   Functions in this module are implementation of sap component actions.
+ *   Details of actions can be found in IEEE-802.2 standard document.
+ *   All functions have one sap and one event as input argument. All of
+ *   them return 0 On success and 1 otherwise.
