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!

+
+When CONFIG_DEVFS_DEBUG is enabled, you can pass several boot options
+to the kernel to debug devfs. The boot options are prefixed by
+"devfs=", and are separated by commas. Spaces are not allowed. The
+syntax looks like this:
+
+devfs=<option1>,<option2>,<option3>
+
+and so on. For example, if you wanted to turn on debugging for module
+load requests and device registration, you would do:
+
+devfs=dmod,dreg
+
+You may prefix "no" to any option. This will invert the option.
+
+
+Debugging Options
+=================
+
+These requires CONFIG_DEVFS_DEBUG to be enabled.
+Note that all debugging options have 'd' as the first character. By
+default all options are off. All debugging output is sent to the
+kernel logs. The debugging options do not take effect until the devfs
+version message appears (just prior to the root filesystem being
+mounted).
+
+These are the options:
+
+dmod		print module load requests to <request_module>
+
+dreg		print device register requests to <devfs_register>
+
+dunreg		print device unregister requests to <devfs_unregister>
+
+dchange		print device change requests to <devfs_set_flags>
+
+dilookup	print inode lookup requests
+
+diget		print VFS inode allocations
+
+diunlink	print inode unlinks
+
+dichange	print inode changes
+
+dimknod		print calls to mknod(2)
+
+dall		some debugging turned on
+
+
+Other Options
+=============
+
+These control the default behaviour of devfs. The options are:
+
+mount		mount devfs onto /dev at boot time
+
+only		disable non-devfs device nodes for devfs-capable drivers
