PCI Hotplug: export the acpi_resource_to_address64 function, as the acpi pci hotplug driver needs it.

Thanks to Adrian Bunk <bunk@fs.tum.de> for pointing this out.

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 :-).
