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!

+	default y
+	---help---
+	  Linux uses the PNPACPI to autodetect built-in
+	  mainboard resources (e.g. parallel port resources).
+
+          Some features (e.g. real hotplug) are not currently
+          implemented.
+
+          If you would like the kernel to detect and allocate resources to
+          your mainboard devices (on some systems they are disabled by the
+          BIOS) say Y here.  Also the PNPACPI can help prevent resource
+          conflicts between mainboard devices and other bus devices.
