Intel Wired LAN Driver Updates 2015-12-01
This series contains updates to i40e and i40evf only.
Helin adds new fields to i40e_vsi to store user configured RSS config data
and the code to use it. Also renamed RSS items to clarify functionality
and scope to users. Fixed a confusing kernel message of enabling RSS size
by reporting it together with the hardware maximum RSS size.
Anjali fixes the issue of forcing writeback too often causing us to not
benefit from NAPI.
Jesse adds a prefetch for data early in the transmit path to help immensely
for pktgen and forwarding workloads. Fixed the i40e driver that was
possibly sleeping inside critical section of code.
Carolyn fixes an issue where adminq init failures always provided a message
that NVM was newer than expected, when this is not always the case for
init_adminq failures. Fixed by adding a check for that specific error
condition and a different helpful message otherwise.
Mitch fixes error message by telling the user which VF is being naughty,
rather than making them guess. Updated the queue_vector array from a
statically-sized member of the adapter structure, to a dynamically-allocated
and -sized array. This reduces the size of the adapter structure and allows
us to support any number of queue vectors in the future without changing the
code.

As soon as we leave the spinlock after the job has been added to the job
queue, we can no longer rely on the job's data to be available.
I have seen a null-pointer dereference due to sched == NULL in
amd_sched_wakeup via amd_sched_entity_push_job and
amd_sched_ib_submit_kernel_helper. Since the latter initializes
sched_job->sched with the address of the ring scheduler, which is
guaranteed to be non-NULL, this race appears to be a likely culprit.

The SCSI sd driver probes SCSI devices asynchronously. The sd_remove()
function, called indirectly by device_del(), waits until asynchronous
probing has finished. Since the block layer queue must only be cleaned
up after probing has finished, device_del() has to be called before
blk_cleanup_queue(). Hence revert commit bf2cf3baa2.

This chip supports two power modes.
1. "one-shot" mode - the chip activates and executes one complete
conversion loop and then shuts itself down. This is the default mode
chosen for raw reads.
2. "continuous" mode - the chip takes continuous measurements.
Continuous mode is more expensive power-wise but may be more reliable.
Add a property so that if preferred, the default power mode for raw
reads can be set to continuous.
Separate one-shot enabling in a separate function that will be used
depending on the chosen power mode. Also create a function for
powering the chip on and off.

aren't mapped. __remove_range() uses dm_btree_lookup_next() for each

slightly different keymap would be needed, but I think we used parts with

Commit fa731ac7ea ("regulator: core: avoid unused variable warning")
introduced a subtle change in how supplies are locked. Where previously
code was always locking the regulator of the current iteration, the new
implementation only locks the regulator if it has a supply. For any
given power tree that means that the root will never get locked.
On the other hand the regulator_unlock_supply() will still release all
the locks, which in turn causes the lock debugging code to warn about a
mutex being unlocked which wasn't locked.
