fb796707d7 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Both conflict were simple overlapping changes.

In the kaweth case, Eric Dumazet's skb_cow() bug fix overlapped the
conversion of the driver in net-next to use in-netdev stats.

6f60f43810 net: qrtr: potential use after free in qrtr_sendmsg()
If skb_pad() fails then it frees the skb so we should check for errors.

c21ef3e343 net: rtnetlink: plumb extended ack to doit function
Add netlink_ext_ack arg to rtnl_doit_func. Pass extack arg to nlmsg_parse
for doit functions that call it directly.

This is the first step to using extended error reporting in rtnetlink.
>From here individual subsystems can be updated to set netlink_ext_ack as
needed.

fceb6435e8 netlink: pass extended ACK struct to parsing functions
Pass the new extended ACK reporting struct to all of the generic
netlink parsing functions. For now, pass NULL in almost all callers
(except for some in the core.)

5052de8def soc: qcom: smd: Transition client drivers from smd to rpmsg
By moving these client drivers to use RPMSG instead of the direct SMD
API we can reuse them ontop of the newly added GLINK wire-protocol
support found in the 820 and 835 Qualcomm platforms.

As the new (RPMSG-based) and old SMD implementations are mutually
exclusive we have to change all client drivers in one commit, to make
sure we have a working system before and after this transition.

a986a05de9 net: qrtr: fix build problems
Having multiple loadable modules with the same name cannot work
with modprobe, and having both net/qrtr/smd.ko and drivers/soc/qcom/smd.ko
results in a (somewhat cryptic) build error:

ERROR: "qcom_smd_driver_unregister" [net/qrtr/smd.ko] undefined!
ERROR: "qcom_smd_driver_register" [net/qrtr/smd.ko] undefined!
ERROR: "qcom_smd_set_drvdata" [net/qrtr/smd.ko] undefined!
ERROR: "qcom_smd_send" [net/qrtr/smd.ko] undefined!
ERROR: "qcom_smd_get_drvdata" [net/qrtr/smd.ko] undefined!
ERROR: "qcom_smd_driver_unregister" [drivers/soc/qcom/wcnss_ctrl.ko] undefined!
ERROR: "qcom_smd_driver_register" [drivers/soc/qcom/wcnss_ctrl.ko] undefined!
ERROR: "qcom_smd_set_drvdata" [drivers/soc/qcom/wcnss_ctrl.ko] undefined!
ERROR: "qcom_smd_send" [drivers/soc/qcom/wcnss_ctrl.ko] undefined!
ERROR: "qcom_smd_get_drvdata" [drivers/soc/qcom/wcnss_ctrl.ko] undefined!

Also, the qrtr driver uses the SMD interface and has a Kconfig dependency,
but also allows for compile-testing when SMD is disabled. However, if
with QCOM_SMD=m and COMPILE_TEST=y we can end up with QRTR_SMD=y and
that fails with a related link error.

The changes the dependency so we can still compile-test the driver but
not have it built-in if SMD is a module, to avoid running in the broken
configuration, and changes the Makefile to provide the driver under
a different module name.
