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.

This fixes the compat_ioctl interface for the case where a NULL handler
is registered. This should produce a "compatible" as opposed to
"translated" interface for the specified ioctl. The patch was sent to
linux-kernel and no one complained (atleast with this second rev).

Currently __bdevname walks the obsolete list of block majors to
find a name for the given dev_t and falls back to unknown-block(%u,%u)
if that's not possible.  Replace this with an attempted get_gendisk() +
disk_name.  This means __bdevname can't be called from irq context
anymore, but as all old irq context callers are using bdevname() now
that fine (and I've added a big comment).
