5d59a6f1ba firewire: remove bogus check in fw_core_handle_request
This check is bogus:
  - Maximum asynchronous payload size for S800...S3200 is 4096.
  - The p->payload_length is totally uninteresting.  Only the
    request->length of the subsequently allocated and initialized
    struct fw_request is of significance.

332ef3310b firewire: fw-sbp2: add a boundary check
Add rudimentary check for the case that the page table overflows due to
merging of s/g elements by the IOMMU.  This would have lead to
overwriting of arbitrary memory.

After this change I expect that an offending command will be
unsuccessfully retried until the scsi_device is taken offline by SCSI
core.  It's a border case and not worth to implement a recovery
strategy.

f139749001 firewire: support S100B...S400B and link slower than PHY
Use a speed probe to determine the speed over 1394b buses and of nodes
which report a link speed less than their PHY speed.

Log the effective maximum speed of newly created nodes in dmesg.

Also, read the config ROM (except bus info block) at the maximum speed
rather than S100.  This isn't a real optimization though because we
still only use quadlet read requests for the entire ROM.

The patch also adds support for S1600 and S3200, although such hardware
does not exist yet.

In case the topology build fails, we want to retain the old topology
info until another reset finishes and results in a valid new tree.  If
we clear card->irm_node to NULL and the topology build fails, we end up
dereferencing a NULL pointer in a few places.
