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!

+	  Technologies, Inc.  These include the Internet PhoneJACK and
+	  Internet LineJACK Telephony Cards. You will get a module called
+	  ixj.
+
+	  For the ISA versions of these products, you can configure the
+	  cards using the isapnp tools (pnpdump/isapnp) or you can use the
+	  isapnp support.  Please read <file:Documentation/telephony/ixj.txt>.
+
+	  For more information on these cards, see Quicknet's web site at:
