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!

+The SA1100 serial port had its major/minor numbers officially assigned:

+> 204 char        Low-density serial ports
+>                   5 = /dev/ttySA0               SA1100 builtin serial port 0
+>                   6 = /dev/ttySA1               SA1100 builtin serial port 1
+>                   7 = /dev/ttySA2               SA1100 builtin serial port 2
+> 
+> 205 char        Low-density serial ports (alternate device)
+>                   5 = /dev/cusa0                Callout device for ttySA0
+>                   6 = /dev/cusa1                Callout device for ttySA1
+>                   7 = /dev/cusa2                Callout device for ttySA2

+
+If you're not using devfs, you must create those inodes in /dev
+on the root filesystem used by your SA1100-based device:
+
+	mknod ttySA0 c 204 5
+	mknod ttySA1 c 204 6
+	mknod ttySA2 c 204 7
+	mknod cusa0 c 205 5
+	mknod cusa1 c 205 6
+	mknod cusa2 c 205 7
+
+In addition to the creation of the appropriate device nodes above, you
+must ensure your user space applications make use of the correct device
+name. The classic example is the content of the /etc/inittab file where
+you might have a getty process started on ttyS0.  In this case:
+
+- replace occurrences of ttyS0 with ttySA0, ttyS1 with ttySA1, etc.
+
+- don't forget to add 'ttySA0', 'console', or the appropriate tty name
+  in /etc/securetty for root to be allowed to login as well.
