  ieee1394: sbp2: add support for disks >2 TB (and 16 bytes long CDBs)
  firewire: sbp2: add support for disks >2 TB (and 16 bytes long CDBs)
  firewire: core: do not DMA-map stack addresses

Increase the command ORB data structure to transport up to 16 bytes long
CDBs (instead of 12 bytes), and tell the SCSI mid layer about it.  This
is notably necessary for READ CAPACITY(16) and friends, i.e. support of
large disks.

The DMA mapping API cannot map on-stack addresses, as explained in
Documentation/DMA-mapping.txt.  Convert the two cases of on-stack packet
payload buffers in firewire-core (payload of lock requests in the bus
manager work and in iso resource management) to slab-allocated memory.

There are a number on-stack buffers for quadlet write or quadlet read
requests in firewire-core and firewire-sbp2.  These are harmless; they
are copied to/ from card driver internal DMA buffers since quadlet
payloads are inlined with packet headers.

  firewire: new stack is no longer experimental
  firewire: net: better FIFO address range check and rcodes
  firewire: net: fix card driver reloading
  firewire: core: fix iso context shutdown on card removal
  firewire: core: fix DMA unmapping in iso buffer removal
  firewire: net: adjust net_device ops
  firewire: net: remove unused code
  firewire: net: allow for unordered unit discovery
  firewire: net: style changes
  firewire: net: add Kconfig item, rename driver
  firewire: add IPv4 support

The new stack is now recommended over the old one if used for industrial
video (IIDC/DCAM) or for storage devices (SBP-2) due to better
performance, improved compatibility, added features, and security.  It
should also be functionally on par with and is more secure than the old
ieee1394 stack in the use case of consumer video devices.

IP-over-1394 support for the new stack is currently emerging, and a
backend of the firedtv DVB driver to the new stack should be available
soon.

The one remaining area where the old stack is still required are audio
devices, as the new stack is not yet able to support the FFADO FireWire
audio framework.

  firewire: core: use more outbound tlabels
  firewire: core: don't update Broadcast_Channel if RFC 2734 conditions aren't met
  firewire: core: prepare for non-core children of card devices
  firewire: core: include linux/uaccess.h instead of asm/uaccess.h
  firewire: add parent-of-unit accessor
  firewire: rename source files
  firewire: reorganize header files
  firewire: clean up includes
  firewire: ohci: access bus_seconds atomically
  firewire: also use vendor ID in root directory for driver matches
  firewire: share device ID table type with ieee1394
  firewire: core: add sysfs attribute for easier udev rules
  firewire: core: check for missing struct update at build time, not run time
  firewire: core: improve check for local node

The AR req handler should not check the generation; higher level code
is the better place to handle bus generation changes.  The target node
ID just needs to be checked for not being the "all nodes" address; in
this case don't handle the request and don't respond.

Use Address_Error and Type_Error rcodes as appropriate.

Fix some problems from "firewire: net: allow for unordered unit
discovery":
  - fwnet_remove was missing a list_del, causing fwnet_probe to crash if
    called after fwnet_remove, e.g. if firewire-ohci was unloaded and
    reloaded.
  - fwnet_probe should set its new_netdev flag only if it actually
    allocated a net_device.
  - Use dev_set_drvdata and dev_get_drvdata instead of deprecated direct
    access to device.driver_data.

If isochronous contexts existed when firewire-ohci was unloaded, the
core iso shutdown functions crashed with NULL dereferences, and buffers
etc. weren't released.

How the fix works:  We first copy the card driver's iso shutdown hooks
into the dummy driver, then fw_destroy_nodes notifies upper layers of
devices going away, these should shut down (including their iso
contexts), wait_for_completion(&card->done) will be triggered after
upper layers gave up all fw_device references, after which the card
driver's shutdown proceeds.

dmap_unmap_page() shall use the same direction as dma_map_page().
