usb-storage: Workaround devices with bogus sense size
Some devices, such as Huawei E169, advertise more than the standard
amount of sense data, causing us to set US_FL_SANE_SENSE, assuming
they support it. However, they subsequently fail the request sense
with that size.
This works around it generically. When a sense request fails due to
a device returning an error, US_FL_SANE_SENSE was set, and that sense
request used a larger sense size, we retry with a smaller size before
giving up.

When the EHCI driver falls behind in its scheduling, the active stream's
first empty microframe may be in the past with respect to the current
microframe. The code attempts to move the starting microframe ("start") N
number of microframes forward, where N is the interval of endpoint.
However, stream->interval is a copy of the endpoint's bInterval, which is
designated in frames for FS devices, and microframes for HS devices.
Convert stream->interval to microframes before using it to move the
starting microframe forward.

If an endpoint is deleted before it's been fully added to the hardware
list, the associated qset will not be fully initialized and an oops will
occur when complete(&qset->remove_complete) is called. This can happen
if a queued URB is cancelled.
Fix this by only removing the qset from the hardware list if the

Reiserfs uses the ioctl callback for its file operations, which means
that its ioctl path is still locked by the bkl, this was synchronizing
with the rest of the filsystem operations. We have changed that by
locking it with the new reiserfs lock but we do that only from the
compat_ioctl callback.
Fix that by locking reiserfs_ioctl() everytime.

The Topology Map of the local node was created in CPU byte order,
then a temporary big endian copy was created to compute the CRC,
and when a read request to the Topology Map arrived it had to be
converted to big endian byte order again.
We now generate it in big endian byte order in the first place.
This also rids us of 1000 bytes stack usage in tasklet context.

Move the static config ROM buffer into the scope of the two callers of
generate_config_rom(). That way the ROM length can be passed over as
return value rather than through a pointer argument.
It also becomes more obvious that accesses to the config ROM buffer have
to be serialized and how this is accomplished. And firewire-core.ko
shrinks a bit as well.

The config ROM image of the local node was created in CPU byte order,
then a temporary big endian copy was created to compute the CRC, and
finally the card driver created its own big endian copy.
We now generate it in big endian byte order in the first place to avoid
one byte order conversion and the temporary on-stack copy of the ROM
image (1000 bytes stack usage in process context). Furthermore, two
1000 bytes memset()s are replaced by one 1000 bytes - ROM length sized
memset.
The trivial fw_memcpy_{from,to}_be32() helpers are now superfluous and
removed. The newly added __compute_block_crc() function will be folded
into fw_compute_block_crc() in a subsequent change.

- The similar queue_delayed_work helpers fw_schedule_bm_work,

convention.
- Two conditional calls of schedule_iso_resource are factored into
another small helper.
- An sbp2_target_get helper is added as counterpart to
sbp2_target_put.

firewire-sbp2 remains unchanged.

If userspace tries to perform a requeue_pi on a non-requeue_pi waiter,
it will find the futex_q->requeue_pi_key to be NULL and OOPS.
Check for NULL in match_futex() instead of doing explicit NULL pointer
checks on all call sites. While match_futex(NULL, NULL) returning
false is a little odd, it's still correct as we expect valid key
references.

The Unit_Characteristics entry of an SBP-2 unit directory is not
mandatory as far as I can tell. If it is missing, we would probably
fail to log in into the target because firewire-sbp2 would not wait for
status after it sent the login request.
The fix moves the cleanup of tgt->mgt_orb_timeout into a place where it
is executed exactly once before login, rather than 0..n times depending
on the target's config ROM. With targets with one or more
Unit_Characteristics entries, the result is the same as before.
