Changes:

  * adds a i2c_clients_command() function to i2c-core which calls
    the ->command() callback of all clients attached to a adapter.
  * make bttv + saa7134 drivers use that function instead of mucking
    with the i2c_adapter struct themself.

This is the first of tree patches for i2c.  Trying to get the i2c
cleanups finshed before 2.6.x, so we (hopefully) don't have a
ever-changing i2c subsystem in 2.7.x again (which is very annonying for
driver maintainance).

Changes:

 * listify i2c-core, i.e. make it use <linux/list.h> instead of
   statically-sized arrays, removed lots of ugly code :)
 * added i2c_(get|put)_adapter, changed i2c-dev.c to use these
   functions instead maintaining is own adapter list.
 * killed the I2C_DF_DUMMY flag which had the strange semantics to
   make the i2c subsystem call driver->attach_adapter on detaches.
   Added a detach_adapter() callback instead.
 * some other minor cleanups along the way ...

This patch makes the state letter in the pr_sname field in core dumps
correct for stopped and zombie threads.  The order needed to be changed when
the TASK_* values changed.  This matches the letters used in sched.c:show_task.

Makes the NAT code and all NAT helpers handle non-linear skbs.
Main trick is to introduce skb_ip_make_writable which handles all
the decloning, linearizing, etc.

Gets rid of some warnings.  Manipulating our own module count inside the
sockopt is safe, because unregistering that sockopt will block.

  o Removed blksize from decnet device parameters - use the device mtu like we
    ought to.
  o Removed /proc/net/decnet_route file - I don't think anybody ever used it
    and it was lacking a full enough description of the routes to be useful.
    ip -D route list is much better :-)
  o Added rt_local_src entry to decnet routes so that we get the local source
    address right when forwarding.
  o Added correct proto argument to struct flowi for routing
  o MSG_MORE in sendmsg (ignored, but accepted whereas before we'd error)
  o /proc/net/decnet converted to seq_file
  o /proc/net/decnet_dev converted to seq_file
  o /proc/net/decnet_cache converted to seq_file
  o Use pskb_may_pull() and add code to linearize skbs on the input path
    except for those containing data.
  o Fixed returned packet code (mostly - some left to do)
  o update_pmtu() method for decnet dst entries (ip_gre device assumes this
    method exists - well I think it does :-)
  o Fixed bug in forwarding to get IE bit set correctly
  o Fixed compile bugs with CONFIG_DECNET_ROUTE_FWMARK pointed out by Adrian
    Bunk
  o Fixed zero dest code to grab an address from loopback
  o Fixed local routes in dn_route_output_slow()
  o Fixed error case in dn_route_input/output_slow() pointed out by Rusty

- 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.

This fixes two bugs introduced by some 2.5 changes:

- O_NDELAY handling typo in floppy_open()

- handling of failed transfers in floppy_end_request()
  (do equivalent of what 2.4 does)

Without first fix I was getting "floppy0: disk absent or changed during
operation" infinite loop on opening and without second fix, infinite loop
on error retry.

Now floppy driver seems to be (somehow) working :-).

This file was _the_ header for block-device related stuff in earlier
Linux versions, but nowdays there's just a few prototypes left that
really belong into blkdev.h or genhd.h (and in one case elevator.h).

This patch moves them over and removes everything but including
blkdev.h from blk.h  Note that blkdev.h gets all the headers that
were included in blk.h inmplicitly too.  Now we can start removing
all references to it an maybe kill it off before 2.6.  *sniff*

This adds ieee1394 for module table registration.
