IEEE1394(r1146): Make the probe callback return an error if problems, and unbind drivers on failure.

Drivers updated: eth1394, baycom_epp, lp486e, plip, 3c359,
olympic, tms380tr.

IEEE-1394 Sync with r1088

- Cleanup Kconfig so that ieee1394 core doesn't require PCI.

- Some function renames to make things consistent.

- Fixup ISO API so that packet-per-buffer and irq-interval work
  correctly.

- Get rid of host list and use driver model for handling host ref count
  and host accounting.

- Get rid of packet semaphore.

- Move bus registration into core ieee1394 initialization.

- Get rid of ancient unused data_be (big-endian) flag in packet struct.

- Fix recursive use of bus_for_each_dev() in nodemgr.

- Revert changes to oui.db. This file is verbatim from IEEE, so if any
  changes should be made, register them with the IEEE database and keep
  this one pristine.

- Fix PCILynx so that it checks for errors on calls to copy_from_user().

- Add ARM API handlers to raw1394.

- Cleanup sbp2's packet sending to accomodate for a case where a packet
  was free'd while sbp2 was waiting on it.

	    - Remove procfs interface.
	    - Fix usage of initdata after init.

	      IRM, etc.

 IEEE1394 : Make bus-nodeid printk's of a consistent format.
 OHCI1394 : Change one printk to a verbose/debug only message.

 IEEE1394 : Kbuildify oui2c.
 ALL      : C construct cleanups, macro namespace cleanups.
 ETH1394  : Limited multicast support. Minor fixes for IPv4 interop.
 ETH1394  : Add ethtool support.

 OHCI1394: Merge CONFIG_PPC_ALL changes.
 DV1394  : Fix broken endian conversions.

- Adds fragementation support to eth1394
- Fix race conditition in packet completion task call
- Fix lack of proper logic in tlabel allocation
- Fix brokeness introduced by "stanford checker fixes for memset" in
  ohci1394
- Add trivial PM resume callback in ohci1394 to support sleep/resume.

- Fix possible memory leak in iso.c
- Added handling for more than 1 Logical_Unit_Number entry in a unit
  directory for SBP-2. This allows for handling the second type of LUN
  that we didn't support yet.

- Remove some 2.4 compatibility macros
- Fix userspace pointer misuse in video1394 ioctl. Caught by the
  Stanford Checker. Gotta love the automated systems.
- Move our hotplug stuff around, to make the transition to putting our
  module dev table in mod_devicetable.h.
- Fix ohci1394 for possible crash with async stream packets. Cleaned up
  some debug messages.

Changes:

  - Convert to a static highlevel handle for all drivers. Gets rid of
    a kmalloc for each driver and consolidates the highlevel handle and
    highlevel ops. Reduces points of failure as well.
  - Move host number allocation to hosts.c, giving all drivers access to
    it.
  - Implemented S800 changes for core and sbp2. Thanks to TI and LaCie
    for hardware to test this. 1394b support coming soon.
  - Convert nodemgr to using a similar device classification hack as
    usb. The old class_num hack I had in place was broken do to its
    removal. This is a much cleaner solution.

- New irq handler prototypes.
- Lots of un-enumurated locking fixes/cleanups (thanks in large part to
  spinlock debug compile options in the kernel).
- Other various trivial fixes.

- Cleaned up hostinfo usage in all drivers and created a central API to
  handle them all.
- Fixup some spinlock mis-usage.
- Remove devfs_handle mis-usage.
- Cleaned up some heavy handed spinlocking to use mutexes instead.
- Add function to send PHY config packets and use to to settle
  IRM/cycle-master/root descrepancies.

 - Cleanup Makefile.
 - Fix potentional crash in dv1394 module unload.
 - Why does ARM's memcpy not return void*? Oh well, work around it in
  eth1394 by not expecting standard behavior.

- Add ioctl32 compat function registration for video1394, dv1394 and
  amdtp.
- Convert SBP-2 driver to new SCSI hotplug host/device interfaces.
- Initial Async ISO (GASP) support.

    wont -> won't (21 occurrences)

- Converts Video1394 to PCI dma.
- Converts ioctl's to standard interface.
- Various minor fixes
- Merges from 2.5.x tree

This covers a lot of ground in the Linux1394 SVN tree.  I haven't had
time to keep in sync with you in a more granular way, so here's a
bohemoth patch.  However, consider it well tested.

 - Cleanup (purge) some of our old compat code (never thouched)
 - Fix dv1394 compilation warnings without devfs
 - Added new config-rom handling features. Allows for on-the-fly
   config-rom generation for dynamic functionality of the host nodes.
 - Convert to workqueue from taskqueue interfaces. This is actually
   abstracted compatibility code between tqueue/workqueue.

Syncronizes with our SVN repo. Merged in all changes from your tree.

ieee1394 updates:
