Both cores are another exceptions. They are not accessed in a standard
way and to they don't need or have wrapping addresses.
This fixes bus scanning after finding such core.

Here's a first batch of patches for 4.6:
* continue the work on multiple Rx queues (Sara)
* add support for beacon storing
used in low power states (Sara)
* cleanups (Rodrigo, Johannes)
* fix the LED behavior for iwldvm (Hubert)
* Use the regular firmware image of WoWLAN (Matti)
* fix 8000 devices for Big Endian machines (Johannes)
* more firmware debug hooks (Golan)

When in AP mode we need to filter in beacons from other APs to update HT
operation mode. As a power optimization the beacons are filtered out when
there are no associated stations. As a result, when there are no
associated stations, we will not update the HT operation mode until a
station connects.
Add a debugfs parameter that allows to disable this optimization.

9000 series supports multi-queue rx. The hardware needs
to be configured with the hash functions to perform and
indirection table that maps hash results to the relevant
CPUs\queues.
Support this configuration.
Add debugfs hook to configure the indirection table in
order to enable performance analysis. The configuration
is stateless, receives a partial or full pattern and sends
the command to the firmware.

The 9000 hardware introduces the frame releaser, which
keeps track of the aggregation window and notifies host
of the window status. This requires in turn updating
the hardware with the RX BA session window size.

Currently firmware is configured to filter out beacons. In case
a beacon was changed - it is waking the host.
However, some vendors change their IEs frequently without any
significant change, and redundant wakeups are triggered as a
result.
As a solution disable beacon filtering when entering d0i3.
Instead, firmware will store the latest beacon and upon exiting
d0i3 it will send it up to the host, so the host can act upon
changes (if there were any).
This beacon will arrive as a dedicated notification - support it
as well.

Currently when the driver is configured with wowlan parameters, and enters
D3 mode, the driver switches the FW image to D3, and when it exists
suspend, it reloads the D0 image.
If the firmware supports the consolidation of the D0 & D3 images there is
no need to load the D3 image on suspend, and no need to reload the D0
image on resume.
Do not switch images on suspend / resume, for firmwares that support
consolidated images.

The 9000 series introduces several changes in the device
DMA operation.
As the device now supports multi-queue rx, several DMA channels
should be configured.
The flows of providing the device with the allocated RBDs now
changes as well - the device maintains a separate table of used
and free table.
The hardware may use the free table to feed RBDs to any queue.
This requires maintaing a shared table to map returned RBDs to
the original RXB - for that purpose the VID is introduced - an
internal identifier of the RB placed in the lower 12 bits and
returned by HW in the used data.
Another change is the support of 64 bit DMA address.

The 9000 series devices will support multi rx queues.
Current code has one static rx queue - change it to allocate
a number of queues per the device capability (pre-9000 devices
have the number of rx queues set to one).
Subsequent generalizations are:
Change the code to access an explicit numbered rx queue only
when the queue number is known - when handling interrupt, when
accessing the default queue and when iterating the queues.
The rest of the functions will receive the rx queue as a pointer.
Generalize the warning in allocation failure to consider the
allocator status instead of a single rx queue status.
Move the rx initial pool of memory buffers to be shared among
all the queues and allocated to the default queue on init.

When the Tx queues are full above a threshold, we
immediately stop the mac80211's queue to stop getting new
packets. This worked until TSO was enabled.
With TSO, one single packet from mac80211 can use many
descriptors since a large send needs to be split into
several segments.
This means that stopping mac80211's queues is not enough
and we also need to ensure that we don't overflow the Tx
queues with one single packet from mac80211.
Add code to transport layer to do just that. Stop
mac80211's queue as soon as the queue is full above the
same threshold as before, and keep pushing the current
packet along with its segments on the queue, but check
that we don't overflow. If that would happen, buffer the
segments, and send them when there is room in the Tx queue
again. Of course, we first need to send the buffered
segments and only then, wake up mac80211's queues.

Same chip is being used by WLAN as well as bluetooth
drivers. Each driver needs to check during initialisation
if firmware is already active or it needs to be freshly
downloaded. If one driver has started downloading the
firmware, other finds the winner flag as false.
mwifiex_check_fw_status() checks firmware status and also
check if WLAN is the winner for firmware downloading.
Once we detect that other interface is downloading
the firmware, we call this routine again with max
poll count to wait until firmware is ready.
This patch splits the routine to avoid checking
winner status unnecessarily multiple times and ensures
that correct messages are displayed to user.
Firmware status poll count is also increased to 150.
