The NVMUpdate tool doesn't necessarily know the ReadOnly map of the current
NVM image, and must try reading and writing words that may be protected.
This generates an error out of the Firmware request that the driver logs.
Unfortunately, this ends up spitting out hundreds of bogus read and write
error message that looks rather messy.
This patch checks the error type and under normal conditions will not print
the typical read and write errors during NVMUpdate. This can be overridden
by enabling the NVM update debugging. This results in a much less messy log
file, and likely many fewer customer support questions.

Fix a bug introduced in the force writeback code, where the interrupt
rate was set to 0 (maximum) by accident.
The driver must correctly set the NOITR fields to avoid ITR update
as a side effect of triggering the software interrupt.

The Kvaser firmware can only read and write messages that are
not crossing the USB endpoint's wMaxPacketSize boundary. While
receiving commands from the CAN device, if the next command in
the same URB buffer crossed that max packet size boundary, the
firmware puts a zero-length placeholder command in its place
then moves the real command to the next boundary mark.
The driver did not recognize such behavior, leading to missing
a good number of rx events during a heavy rx load session.
Moreover, a tx URB context only gets freed upon receiving its
respective tx ACK event. Over time, the free tx URB contexts
pool gets depleted due to the missing ACK events. Consequently,
the netif transmission queue gets __permanently__ stopped; no
frames could be sent again except after restarting the CAN
newtwork interface.

Upon a URB submission failure, the driver calls usb_free_urb()

When reading from the error queue, msg_name and msg_control are only
populated for some errors. A new exception for empty timestamp skbs
added a false positive on icmp errors without payload.
`traceroute -M udpconn` only displayed gateways that return payload
with the icmp error: the embedded network headers are pulled before
sock_queue_err_skb, leaving an skb with skb->len == 0 otherwise.
Fix this regression by refining when msg_name and msg_control
branches are taken. The solutions for the two fields are independent.
msg_name only makes sense for errors that configure serr->port and
serr->addr_offset. Test the first instead of skb->len. This also fixes
another issue. saddr could hold the wrong data, as serr->addr_offset
is not initialized in some code paths, pointing to the start of the
network header. It is only valid when serr->port is set (non-zero).
msg_control support differs between IPv4 and IPv6. IPv4 only honors
requests for ICMP and timestamps with SOF_TIMESTAMPING_OPT_CMSG. The
skb->len test can simply be removed, because skb->dev is also tested
and never true for empty skbs. IPv6 honors requests for all errors
aside from local errors and timestamps on empty skbs.
In both cases, make the policy more explicit by moving this logic to
a new function that decides whether to process msg_control and that
optionally prepares the necessary fields in skb->cb[]. After this
change, the IPv4 and IPv6 paths are more similar.
The last case is rxrpc. Here, simply refine to only match timestamps.

Intel Wired LAN Driver Updates 2015-03-07
This series contains updates to i40e and i40evf only.
Most notably, Greg provides the patch to remove the dreaded configfs
changes in the driver.
Shannon cleans up a sparse warning by simply straighting out the code
so it is less convoluted. Fixes an issue where the vector allocation
was trying too hard to save vectors for VMDq, to the point of not giving
the PF enough when in a tight situation, such as an NPAR partition.
Changed the driver to make sure that the PF will get all the queues and
vectors it wants to fill out its destiny. Cleans up reporting to only
print the port and VEB stats if it is the first partition of a
multiplexed port.
Catherine cleans up some duplicated code by simply removing the duplicate
code.
Kamil cleans up the driver by removing an un-needed endian conversion
because it is already done by a register read function.
Jesse fixes a variable width of a datatype, where a u16 should have been
a u32. Also cleans up debug_read_register() to resolve some sparse
warnings. Updates the driver to use prefetch() to get the next Tx
descriptor, like in ixgbe, to improve performance.
Akeem moves around code to enable/disable loopback so that other non-SRIOV
supported driver functions can take advantage of the changes.
Anjali cleans up the logging for adding/deleting FD-SB filters, since
ethtool shows all the filters on an interface. Updates the driver to
use l4_tunnel type generically to keep code flow simple. Simplifies
the RSS code since the driver initializes the rss_size_max in sw_init.

net/macb: merge at91_ether driver into macb driver
The rm9200 boards use the dedicated at91_ether driver instead of the
regular macb driver.
Both the macb and at91_ether drivers can be compiled as separated
modules.
Since the at91_ether driver uses code from the macb driver, at91_ether.ko
depends on macb.ko.
However the macb.ko module always fails to load on rm9200 boards: the
macb_probe() function expects a hclk clock which doesn't exist on rm9200.
Then the at91_ether.ko can't be loaded in turn due to unresolved
dependencies.
This series of patches fix this issue by merging at91_ether into macb.
Patch 1 is fixing a problem that might happen when enabling ARM
multi-platform suppot.
Changes since v3:
- move "net: macb: remove #if defined(CONFIG_ARCH_AT91) sections" patch
into this series to avoid dependency on other patch series.
Changes since v2:
- rebase after changed brought by commit "net: macb: remove #if

Changes since v1:

macb and at91_ether drivers can be compiled as modules, but the at91_ether
driver use some functions and variables defined in the macb one, thus
creating a dependency on the macb driver.
Since these drivers are sharing the same logic we can easily merge
at91_ether into macb.
In order to factorize common probing logic we've added an ->init() function
to struct macb_config (the structure associated with the compatible
string), and moved macb specific init code from macb_probe to macb_init.

Apparently, the threshold for large contact area seems to be rather low on
some devices, causing the touchpad to frequently freeze during normal
usage. Because we do now know how we are supposed to use the value in
question, this commit just drops the related code completely.

These PS/2 commands make some touchpads stop responding, so this commit
adds some dummy functions to replace the generic implementation. Because
scale changes were not encapsulated in a method of struct psmouse yet, this
commit adds a method set_scale to psmouse.

We don't know whether x_max or y_max really hold the maximum possible
coordinates, and we don't know for sure whether we correctly interpret the
coordinates sent by the touchpad, so we clamp the reported values to
prevent confusion in userspace code.

The size has in most cases already been fetched from the touchpad, the
hardcoded values should have been removed.

While compiling the following warning occurs:
WARNING: net/built-in.o(.init.text+0x602c): Section mismatch in
reference from the function bt_init() to the function
.exit.text:sco_exit()
The function __init bt_init() references
a function __exit sco_exit().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
sco_exit() so it may be used outside an exit section.
Since commit 6d785aa345 ("Bluetooth:
Convert mgmt to use HCI chan registration API") the function "sco_exit"
is used inside of function "bt_init". The suggested solution by remove
the __exit annotation solved this issue.
