====================
Altera TSE: Fix Sparse errors and misc issues
This is version 2 of a patch series to correct sparse errors, cppcheck
warnings, and workaound a multicast filtering issue in the Altera TSE
Ethernet driver. Multicast filtering is not working as expected, so if
present in the hardware will not be used and promiscuous mode enabled
instead. This workaround will be replaced with a working solution when
completely debugged, integrated and tested.
Version 2 is different from the first submission by breaking out the
workaround as a seperate patch and addressing a few structure instance
declarations by making them const per review comments.
If you find this patch acceptable, please consider this for inclusion into
the Altera TSE driver source code.

rtnetlink: wait for unregistering devices in rtnl_link_unregister()
From: Cong Wang <cwang@twopensource.com>
commit 50624c934db18ab90 (net: Delay default_device_exit_batch until no
devices are unregistering) introduced rtnl_lock_unregistering() for
default_device_exit_batch(). Same race could happen we when rmmod a driver
which calls rtnl_link_unregister() as we call dev->destructor without rtnl
lock.
For long term, I think we should clean up the mess of netdev_run_todo()
and net namespce exit code.

The attached change significantly improves the performance of the LWS-CAS code
in syscall.S.
This allows a number of packages to build (e.g., zeromq3, gtest and libxs)
that previously failed because slow LWS-CAS performance under contention. In
particular, interrupts taken while the lock was taken degraded performance
significantly.
The change does the following:
1) Disables interrupts around the CAS operation, and
2) Changes the loads and stores to use the ordered completer, "o", on
PA 2.0. "o" and "ma" with a zero offset are equivalent. The latter is
accepted on both PA 1.X and 2.0.
The use of ordered loads and stores probably makes no difference on all
existing hardware, but it seemed pedantically correct. In particular, the CAS
operation must complete before LDCW lock is released. As written before, a
processor could reorder the operations.
I don't believe the period interrupts are disabled is long enough to
significantly increase interrupt latency. For example, the TLB insert code is
longer. Worst case is a memory fault in the CAS operation.

This patch adds the device tree to support Toradex Colibri T30, a

The module consists of a Tegra 30 SoC, two PMIC, DDR3L RAM, eMMC,
a LM95245 temperature sensor and an AX88772B USB Ethernet
Controller. Furthermore, there is a STMPE811 and SGTL5000 audio
codec which are not yet supported. Anything that is not self
