Having struct qos_priv containing a single integer, and carrying a

into struct mlme_priv, which is the only place qos_priv was used
anyway, and get rid of the header file.

Split the old work handler into a workqueue for processing

clearing the event, and leave the old handler to just handle event

802154: some cleanups and fixes
This series adds some definitions for 802.15.4 header fields that were missing,
changes 6lowpan fragmentation to be aware of security headers and fixes
802.15.4 datagram socket sendmsg(), which was entirely incompliant to date.
Also a few minor changes to mac_cb handling, mark a single-use function static,
and correctly check for EMSGSIZE conditions during wpan_header_create.
Changes since v1:
* rename mac_cb_alloc to mac_cb_init
* catch all error cases of sendmsg() instead of only !conn && msg_name
* redo 6lowpan fragmentation to not clone lower layer headers

802.15.4 datagram sockets do not currently have a compliant sendmsg().
The destination address supplied is always ignored, and in unconnected
mode, packets are broadcast instead of dropped with -EDESTADDRREQ. This
patch fixes 802.15.4 dgram sockets to be compliant, i.e.
!conn && !msg_name => -EDESTADDRREQ
!conn && msg_name => send to msg_name
conn && !msg_name => send to connected
conn && msg_name => -EISCONN

Currently, 6lowpan creates one 802.15.4 MAC header for the original
packet the device was given by upper layers and reuses this header for
all fragments, if fragmentation is required. This also reuses frame
sequence numbers, which must not happen. 6lowpan also has issues with
fragmentation in the presence of security headers, since those may imply
the presence of trailing fields that are not accounted for by the
fragmentation code right now.
Fix both of these issues by properly allocating fragment skbs with
headromm and tailroom as specified by the underlying device, create one
header for each skb instead of reusing the original header, let the
underlying device do the rest.

The current mac_cb handling of ieee802154 is rather awkward and limited.
Decompose the single flags field into multiple fields with the meanings
of each subfield of the flags field to make future extensions (for
example, link-layer security) easier. Also don't set the frame sequence
number in upper layers, since that's a thing the MAC is supposed to set
on frame transmit - we set it on header creation, but assuming that
upper layers do not blindly duplicate our headers, this is fine.

The current WPAN header creation code checks for EMSGSIZE conditions,
but does not account for the MIC field that link layer security may add
at the end of the frame. Now that we can accurately calculate the
maximum payload size of packets, use that to check for EMSGSIZE
conditions.

When dealing with 802.15.4, one often has to know the maximum payload
size for a given packet. This depends on many factors, one of which is
whether or not a security header is present in the frame. These
definitions and functions provide an easy way for any upper layer to
calculate the maximum payload size for a packet. The first obvious user
for this is 6lowpan, which duplicates this calculation and gets it
partially wrong because it ignores security headers.

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.

When a new device is added below a hotplug bridge, the bridge's secondary
bus speed and the device's bus speed must match. The shpchp driver
previously checked the bridge's *primary* bus speed, not the secondary bus
speed.
This caused hot-add errors like:
shpchp 0000:00:03.0: Speed of bus ff and adapter 0 mismatch
Check the secondary bus speed instead.

This patch adds the device tree to support Toradex Colibri T30, a
computer on module which can be used on different carrier boards.
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
contained on the module is disabled by default.
The device tree for the Evaluation Board includes the modules
device tree and enables the supported pheripherials of the carrier
board (the Evaluation Board supports almost all of them).

Add the corresponding trace if we have a full match in a non-terminal
rule. Note that the traces will look slightly different than in
x_tables since the log message after all expressions have been
evaluated (contrary to x_tables, that emits it before the target
action). This manifests in two differences in nf_tables wrt. x_tables:
1) The rule that enables the tracing is included in the trace.
2) If the rule emits some log message, that is shown before the
trace log message.
