variable 'XYZ' set but not used.
sbp2.c, unit_characteristics:
The underlying problem which was spotted here --- an incomplete
implementation --- is already 50% fixed in drivers/firewire/sbp2.c which
observes mgt_ORB_timeout but not yet ORB_size.
raw1394.c, length_conflict; dv1394.c, ts_off:
Impossible to tell why these variables are there. We can safely remove
them though because we don't need a compiler warning to realize that we
are dealing with (at least stylistically) flawed code here.
dv1394.c, packet_time:
This was used in debug macro that is only compiled in with
DV1394_DEBUG_LEVEL >= 2 defined at compile-time. Just drop it since
nobody debugs dv1394 anymore. Avoids noise in regular kernel builds.
dv1394.c, ohci; eth1394.c, priv:
These variables clearly can go away. Somebody wanted to use them but
then didn't (or not anymore).
Note, all of this code is considered to be at its end of life and is
thus not really meant to receive janitorial updates anymore. But if we
can easily remove noisy warnings from kernel builds, we should.

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

After ieee1394 was converted away from class_device like the networking
subsystem was already in 2.6.21, eth1394's device may point to the
fw-host device as its parent again like in 2.6.20.
This affects userspace tools which examine the sysfs representation of
eth1394's device.

This patch fixes a problem that occurs when packets cannot be sent across
the ieee1394 bus and we return NETDEV_TX_BUSY in the net driver "hard start
xmit" routine ether1394_tx. When we return NETDEV_TX_BUSY the stack will
call ether1394_tx again with the same skb. So we need to restore the header
to look like it did before we munged it for xmit over ieee1394.

This adds a real parent device to eth1394's ethX device like in Linux
2.6.20 and older. However, due to unfinished conversion of the ieee1394
away from class_device, we now refer to the FireWire controller's PCI
device as the parent, not to the ieee1394 driver's fw-host device.
Having a real parent device instead of a virtual one allows udev scripts
to distinguish eth1394 interfaces from networking bridges, bondings and
the likes.

When eth1394 was unable to acquire a transaction label, it just dropped
outgoing packets without attempt to resend them later.
The transmit queue is now halted if no tlabel is available to
->hard_start_xmit(). A workqueue job is then scheduled to catch the
moment when ieee1394 recycled the next lot of tlabels.

Until now, ieee1394 put an IP-over-1394 capability entry into each new
host's config ROM. As soon as the controller was initialized --- i.e.
right after modprobe ohci1394 --- this entry triggered a hotplug event
which typically caused auto-loading of eth1394.
This irritated or annoyed many users and distributors. Of course they
could blacklist eth1394, but then ieee1394 wrongly advertized IP-over-
1394 capability to the FireWire bus.
Therefore
- remove the offending kernel config option
IEEE1394_CONFIG_ROM_IP1394,
- let eth1394 add the ROM entry by itself, i.e. only after eth1394 was
loaded.
This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 .
To emulate the behaviour of older kernels, simply add the following to
to /etc/modprobe.conf:
install ohci1394 /sbin/modprobe eth1394; \
/sbin/modprobe --ignore-install ohci1394
Note, autoloading of eth1394 when an _external_ IP-over-1394 capable
device is discovered is _not_ affected by this patch.

The networking subsystem has been converted from class_device to device
but ieee1394 hasn't. This results in a 100% reproducible NULL pointer

module is still loaded.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).
