Merge branch 'trivial-2.6.23' of git://git.kernel.dk/data/git/linux-2.6-block

* 'trivial-2.6.23' of git://git.kernel.dk/data/git/linux-2.6-block:
  Documentation/block/barrier.txt is not in sync with the actual code: - blk_queue_ordered() no longer has a gfp_mask parameter - blk_queue_ordered_locked() no longer exists - sd_prepare_flush() looks slightly different
  Use list_for_each_entry() instead of list_for_each() in the block device
  Make a "menuconfig" out of the Kconfig objects "menu, ..., endmenu",
  block/Kconfig already has its own "menuconfig" so remove these
  Use menuconfigs instead of menus, so the whole menu can be disabled at once

This enables support for the Atari ACSI interface. The driver
supports hard disks and CD-ROMs, which have 512-byte sectors, or can
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
driver is also the basis for certain other drivers for devices
attached to the ACSI bus: Atari SLM laser printer, BioNet-100
Ethernet, and PAMsNet Ethernet. If you want to use one of these
devices, you need ACSI support, too.
To compile this driver as a module, choose M here: the

If you have a CD-ROM drive that is neither SCSI nor IDE/ATAPI, say Y
here, otherwise N. Read the CD-ROM-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about these CD-ROM drives. If you are unsure what you
have, say Y and find out whether you have one of the following
drives.
For each of these drivers, a <file:Documentation/cdrom/{driver_name}>
exists. Especially in cases where you do not know exactly which kind
of drive you have you should read there. Most of these drivers use a
file drivers/cdrom/{driver_name}.h where you can define your
interface parameters and switch some internal goodies.
To compile these CD-ROM drivers as a module, choose M instead of Y.
If you want to use any of these CD-ROM drivers, you also have to
answer Y or M to "ISO 9660 CD-ROM file system support" below (this
answer will get "defaulted" for you if you enable any of the Linux
CD-ROM drivers).

drivers -- is NOT for CD-ROM drives with IDE/ATAPI interfaces, such
as Aztech CDA269-031SE. Please read the file

Sound Blaster interface. Please read the file
<file:Documentation/cdrom/sbpcd>.
The Matsushita CR-521, CR-522, CR-523, CR-562, CR-563 drives
(sometimes labeled "Creative"), the Creative Labs CD200, the
Longshine LCS-7260, the "IBM External ISA CD-ROM" (in fact a CR-56x
model), the TEAC CD-55A fall under this category. Some other
"electrically compatible" drives (Vertos, Genoa, some Funai models)
are currently not supported; for the Sanyo H94A drive currently a
separate driver (asked later) is responsible. Most drives have a
uniquely shaped faceplate, with a caddyless motorized drawer, but
without external brand markings. The older CR-52x drives have a
caddy and manual loading/eject, but still no external markings. The
driver is able to do an extended auto-probing for interface
addresses and drive types; this can help to find facts in cases you
are not sure, but can consume some time during the boot process if
none of the supported drives gets found. Once your drive got found,
you should enter the reported parameters into
<file:drivers/cdrom/sbpcd.h> and set "DISTRIBUTION 0" there.
This driver can support up to four CD-ROM controller cards, and each
card can support up to four CD-ROM drives; if you say Y here, you
will be asked how many controller cards you have. If compiled as a
module, only one controller card (but with up to four drives) is
usable.
If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM
