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!

+config WATCHDOG
+	bool "Watchdog Timer Support"
+	---help---
+	  If you say Y here (and to one of the following options) and create a
+	  character special file /dev/watchdog with major number 10 and minor
+	  number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
+	  subsequently opening the file and then failing to write to it for
+	  longer than 1 minute will result in rebooting the machine. This
+	  could be useful for a networked machine that needs to come back
+	  online as fast as possible after a lock-up. There's both a watchdog
+	  implementation entirely in software (which can sometimes fail to
+	  reboot the machine) and a driver for hardware watchdog boards, which
+	  are more robust and can also keep track of the temperature inside
+	  your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
+	  in the kernel source.
+
+	  The watchdog is usually used together with the watchdog daemon
+	  which is available from
+	  <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
+	  also monitor NFS connections and can reboot the machine when the process
+	  table is full.
+
+	  If unsure, say N.
+
+config WATCHDOG_NOWAYOUT
+	bool "Disable watchdog shutdown on close"
+	depends on WATCHDOG
+	help
+	  The default watchdog behaviour (which you get if you say N here) is
+	  to stop the timer if the process managing it closes the file
+	  /dev/watchdog. It's always remotely possible that this process might
+	  get killed. If you say Y here, the watchdog cannot be stopped once
+	  it has been started.
