Linux-2.6.12-rc2v2.6.12-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!

+          If you want to use the floppy disk drive(s) of your PC under Linux,

+          be switched to that mode. Due to the ACSI command format, only disks
+          up to 1 GB are supported. Special support for certain ACSI to SCSI
+          adapters, which could relax that, isn't included yet. The ACSI

+        ---help---
+          There are many external CD-ROM and disk devices that connect through
+          your computer's parallel port. Most of them are actually IDE devices
+          using a parallel port IDE adapter. This option enables the PARIDE

+          Read <file:Documentation/paride.txt> for more information.
+
+          If you have said Y to the "Parallel-port support" configuration
+          option, you may share a single port between your printer and other
+          parallel port devices. Answer Y to build PARIDE support into your
+          kernel, or M if you would like to build it as a loadable module. If
+          your parallel port support is in a loadable module, you must build
+          PARIDE as a module. If you built PARIDE support into your kernel,
+          you may still build the individual protocol modules and high-level
+          drivers as loadable modules. If you build this support as a module,
+          it will be called paride.
+
+          To use the PARIDE support, you must say Y or M here and also to at
+          least one high-level driver (e.g. "Parallel port IDE disks",
+          "Parallel port ATAPI CD-ROMs", "Parallel port ATAPI disks" etc.) and

+
+          The umem driver has not yet been allocated a MAJOR number, so

+        ---help---
+          The User-Mode Linux port includes a driver called UBD which will let
+          you access arbitrary files on the host computer as block devices.
+          Unless you know that you do not need such virtual block devices say
+          Y here.
+
+config BLK_DEV_UBD_SYNC
+        bool "Always do synchronous disk IO for UBD"
+        depends on BLK_DEV_UBD
+        ---help---
+          Writes to the virtual block device are not immediately written to the
+          host's disk; this may cause problems if, for example, the User-Mode
+          Linux 'Virtual Machine' uses a journalling filesystem and the host
+          computer crashes.
+
+          Synchronous operation (i.e. always writing data to the host's disk
+          immediately) is configurable on a per-UBD basis by using a special
+          kernel command line option.  Alternatively, you can say Y here to
+          turn on synchronous operation by default for all block devices.
+
+          If you're running a journalling file system (like reiserfs, for
+          example) in your virtual machine, you will want to say Y here.  If
+          you care for the safety of the data in your virtual machine, Y is a
+          wise choice too.  In all other cases (for example, if you're just
+          playing around with User-Mode Linux) you can choose N.

+
+config BLK_DEV_LOOP
+        tristate "Loopback device support"
+        ---help---
+          Saying Y here will allow you to use a regular file as a block
+          device; you can then create a file system on that block device and
+          mount it just as you would mount other block devices such as hard
+          drive partitions, CD-ROM drives or floppy drives. The loop devices
+          are block special device files with major number 7 and typically
+          called /dev/loop0, /dev/loop1 etc.
+
+          This is useful if you want to check an ISO 9660 file system before
+          burning the CD, or if you want to use floppy images without first
+          writing them to floppy. Furthermore, some Linux distributions avoid
+          the need for a dedicated Linux partition by keeping their complete
+          root file system inside a DOS FAT file using this loop device
+          driver.
+
+          To use the loop device, you need the losetup utility, found in the
+          util-linux package, see
+          <ftp://ftp.kernel.org/pub/linux/utils/util-linux/>.
+
+          The loop device driver can also be used to "hide" a file system in
+          a disk partition, floppy, or regular file, either using encryption
+          (scrambling the data) or steganography (hiding the data in the low
+          bits of, say, a sound file). This is also safe if the file resides
+          on a remote file server.
+
+          There are several ways of encrypting disks. Some of these require
+          kernel patches. The vanilla kernel offers the cryptoloop option
+          and a Device Mapper target (which is superior, as it supports all
+          file systems). If you want to use the cryptoloop, say Y to both
+          LOOP and CRYPTOLOOP, and make sure you have a recent (version 2.12
+          or later) version of util-linux. Additionally, be aware that
+          the cryptoloop is not safe for storing journaled filesystems.
+
+          Note that this loop device has nothing to do with the loopback
+          device used for network connections from the machine to itself.
+
+          To compile this driver as a module, choose M here: the
+          module will be called loop.
+
+          Most users will answer N here.

+
+          WARNING: This device is not safe for journaled file systems like
+          ext3 or Reiserfs. Please use the Device Mapper crypto module

+          block devices, i.e. it will be able to use block devices exported by
+          servers (mount file systems on them etc.). Communication between
+          client and server works over TCP/IP networking, but to the client
+          program this is hidden: it looks like a regular local file access to
+          a block device special file such as /dev/nd0.
+
+          Network block devices also allows you to run a block-device in
+          userland (making server and client physically the same computer,
+          communicating using the loopback network device).
+
+          Read <file:Documentation/nbd.txt> for more information, especially
+          about where to find the server code, which runs in user space and
