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!

+# We are using a recursive build, so we need to do a little thinking
+# to get the ordering right.
+#
+# Most importantly: sub-Makefiles should only ever modify files in
+# their own directory. If in some directory we have a dependency on
+# a file in another dir (which doesn't happen often, but it's often
+# unavoidable when linking the built-in.o targets which finally
+# turn into vmlinux), we will call a sub make in that other dir, and
+# after that we are sure that everything which is in that other dir
+# is now up to date.
+#
+# The only cases where we need to modify files which have global
+# effects are thus separated out and done before the recursive
+# descending is started. They are now explicitly listed as the
+# prepare rule.
