Hi John,
This is probably the last pull request for 3.14.
I have here a rework of the interrupt handling to meet RT kernel
requirements - basically we don't take any lock in the primary interrupt
handler. This gave me a good reason to clean things up a bit on the way.
There is also a fix of the QoS mapping along with a few workarounds for
hardware / firmware issues that are hard to hit.
Three fixes suggested by static analyzers, and other various stuff.
Most importantly, I update the Copyright note to include the new year.
I know it is quite late in the cycle (and probably not the best period
to expect responsiveness:)) but I want to hope that this it will still
make it to 3.14.

This lock was never acquired in the primary interrupt
handler, but since it was acquired along with irq_lock
which had to disable interrupts, rxq->lock had to disable
interrupts too.
Now that trans_pcie->irq_lock isn't acquired in the primary
interrupt handler, rxq->lock can let interrupt enabled.

From: Emmanuel Grumbach <[email protected]>
Separate the code that simply disables interrupt in the
hardware and the code that checks what interrupt fired.
This will be useful to move the second part in the threaded
handler which will be done in a future patch.

From: Emmanuel Grumbach <[email protected]>
The firmware needs to be stopped quickly (100ms) after the
RFKILL interrupt fired. Failing to do so would allow the
firmware to access the radio registers which would lead to
a hardware error.
Before this change, we would kill the firmware only when
mac80211 stops the device which can take a fair amount of
time. Take a shortcut by stopping the device right away
in the interrupt.
This is not relevant if the current firmware is INIT
firmware since that firmware can run while in RFKILL.

From: Emmanuel Grumbach <[email protected]>
Under very specific circumstances, the firmware might
ignore a host command. This was debugged and we ended up
seeing that the power management hardware was faulty.
In order to workaround this issue, we keep the NIC awake
as long as we have host commands in flight. This will avoid
to put the hardware into buggy condition.

we now have:

Since iwl_trans_pcie_alloc_ict is called in the PCIe
allocation code, we always set CSR_INT_BIT_RX_PERIODIC.
Move that bit to the default list of interrupts we enable
and simplify the code.
Also use dma_zalloc_ and avoid to memset the memory
afterwards.
trans_pcie->ict_index is 0 since trans_pcie has just been
kzalloced, remove the redundant assignment.

1.7.9.5
From: Emmanuel Grumbach <[email protected]>
The AC / fifo mapping was wrong - BE packets landed in VO
FIFO. The iwl_mvm_tx_fifo enumeration isn't in the same
order as ieee80211_ac_numbers enumeration.
Since the firmware relies on fifo / ac mapping - this led
to wrong behavior. E.g. the firmware sends beacon with the
same QoS parameters as VO, and it actually took the
parameters of BK. There are probably more severe issues.

1.7.9.5
From: Eyal Shapira <[email protected]>
Found by klocwork analysis.
mvm could be NULL which may cause a NULL dereference
in a theoretical call flow
rs_fill_lq_cmd(mvm = NULL, ...)
rs_build_rates_table
rs_fill_rates_for_column
ucode_rate_from_rs_rate
IWL_ERR(mvm,...)
No real reason for passing NULL to rs_fill_lq_cmd so fix that.

These functions are meant to return an interrupt cause and
not an irqreturn_t.
We still return IRQ_HANDLED if we had an error and IRQ_NONE
if our device hasn't fired any interrupt.

From: Emmanuel Grumbach <[email protected]>
This was useful when the handling was not in the same
context as the interrupt cause retrieval: we could have
several hard interrupts until the handler gets called.
Since we retrieve the interrupt cause in the handler itself,
there is no need to OR the interrupt causes.

This is useless and introduces a dependency between rfkill
and stop_device - the op_mode can't call stop_device from
the rfkill notification since it would lead to an endless
recursion.
Next patches will need to do so.

Instead of always calling ieee80211_beacon_loss() on every missed
beacons notification, call this function only if the number of
consecutive missed beacons from last rx is higher than a predefined
threshold.

Track the interrupt mask in software, making it exactly
what is configured in the interrupt mask register in the
hardware.
This allows not to access the register from the interrupt
handler. This was the case for ICT interrupt already, but
not for non-ICT interrupt.

Calling stop_device when start_fw wasn't called would issue:
Stopping tx queues that aren't allocated...
Also allow the op_mode to call stop_device and then to
disable the Tx queues - in that case just silently ignore
the disabling on the Tx queues, since the PRPH registers
aren't reachable any more.

This allows to format it at will using external tools.
Since different teams want it in different formats, dump
the raw data and everyone can play with the data the way
they want.
While at it - make this code slightly more robust by making
the required verification on the offsets / length in the
write handler.

From: Ilan Peer <[email protected]>
Currently, the MAC context tsf_id assignment and the master/slave
relations are determined only when a new vif is added, as part
of the MAC context resource allocation. However, at this stage, the
beacon interval is not known, and thus could not be taken into account
in the master-slave algorithm.
To fix this, recalculate the MAC context tsf_id assignment,
just before the MAC context is activated, i.e., just before
a station VMAC is configured to associated and before an AP
VMAC is started.
