369d742def e1000e: don't poke PHY registers to retreive link status
Apparently poking the link status registers when autonegotiation
is running on the PHY might botch the PHY link on 80003es2lan
devices. While this is a very rare condition we can completely
avoid it alltogether by just using the MAC link bits to provide
the proper information to ethtool.

3f88ce495b [netdrvr] forcedeth: improved probe info; dev_printk() cleanups
main change:
* greatly improve per-NIC probe diagnostic output.  Similar to other
  net drivers, print out MAC address, PHY info, and various hardware and
  software flags that may be relevant.

other changes:
* similar to other net drivers, only print the initial version message
  when we have found at least one board.

* don't bother to print error message when pci_enable_device() fails,
  it will do so for us.

* use dev_printk() rather than printk() in nv_probe().  This gives
  use a standardized output similar to the rest of the kernel, and
  eliminates the need to manually print out PCI bus id.

* use DRV_NAME constant where appropriate

* clean struct pci_driver indentation

ee71c2f9ee firewire: fw-ohci: enforce read order for selfID generation
It seems unlikely, but access to self_id_cpu[0] could at least in theory
be deferred until after the loop over self_id_cpu[1..n] or even after
the subsequent reg_read.  Enforce the desired order by a read barrier.

Also prevent the reg_read from being reordered relative to the for loop.
This isn't necessary if the loop's conditional printk counts as an
implicit barrier, but better make it explicit.

(self_id_cpu[] is a coherent DMA buffer.)

df8ec2490f firewire: fw-sbp2: use an own workqueue (fix system responsiveness)
Firewire-sbp2 did very uncooperative things in the kernel's shared
workqueue:  Sleeping until reception of management status from the
target for up to 2 seconds, and performing SCSI inquiry and all of the
setup of SCSI command set drivers via scsi_add_device.  If there were
transient or permanent error conditions, this caused long blockage of
the kernel's events process, noticeable e.g. by blocked keyboard input.

We now allocate a workqueue process exclusive to fw-sbp2.  As a side
effect, this also increases parallelism of fw-sbp2's login and reconnect
work versus fw-core's device discovery and device update work which is
performed in the shared workqueue.

2df222b8f8 firewire: fw-sbp2: expose module parameter for workarounds
On rare occasions, the ability to set one of the workaround flags at
runtime may save the day.

People who experience I/O errors with firewire-sbp2 while the old sbp2
driver worked for them should try workarounds=1 and report to the devel
mailinglist whether that improves things.  Firewire-sbp2 defaults to the
SCSI stack's maximum transfer size per command, while sbp2 limits them
to 128 kBytes.  Flag 1 accomplishes just that.

is not true, on receiving a signal (might never happen in practice, as
it ignores signals). But considering kthread_stop() must not be mixed with
kthreads that can exit on their own, I think changing the code like this
is clearer. This change means the thread can cut its sleep short when
receive a signal but looking at the code around, that sounds okay (and
again, it might never actually recieve a signal in practice).
