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!

+/*
+ * A constraint is a condition that must be satisfied in
+ * order for one or more permissions to be granted.
+ * Constraints are used to impose additional restrictions
+ * beyond the type-based rules in `te' or the role-based
+ * transition rules in `rbac'.  Constraints are typically
+ * used to prevent a process from transitioning to a new user
+ * identity or role unless it is in a privileged type.
+ * Constraints are likewise typically used to prevent a
+ * process from labeling an object with a different user
+ * identity.
