Alexey Dobriyan 5b5e0928f7 lib/vsprintf.c: remove %Z support
Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.

Use BUILD_BUG_ON in a couple ATM drivers.

In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement.  Hopefully this patch inspires
someone else to trim vsprintf.c more.

If the rx data comes when the driver is canceling the rx urb, the host
controller would stop getting the data from the device and continue
it after next rx urb is submitted. That is, one continuing data is
split into two different urb buffers. That let the driver take the
data as a rx descriptor, and unexpected behavior happens.

David S. Miller 2745529ac7 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Couple conflicts resolved here:

1) In the MACB driver, a bug fix to properly initialize the
   RX tail pointer properly overlapped with some changes
   to support variable sized rings.

2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix
   overlapping with a reorganization of the driver to support
   ACPI, OF, as well as PCI variants of the chip.

3) In 'net' we had several probe error path bug fixes to the
   stmmac driver, meanwhile a lot of this code was cleaned up
   and reorganized in 'net-next'.

4) The cls_flower classifier obtained a helper function in
   'net-next' called __fl_delete() and this overlapped with
   Daniel Borkamann's bug fix to use RCU for object destruction
   in 'net'.  It also overlapped with Jiri's change to guard
   the rhashtable_remove_fast() call with a check against
   tc_skip_sw().

5) In mlx4, a revert bug fix in 'net' overlapped with some
   unrelated changes in 'net-next'.

6) In geneve, a stale header pointer after pskb_expand_head()
   bug fix in 'net' overlapped with a large reorganization of
   the same code in 'net-next'.  Since the 'net-next' code no
   longer had the bug in question, there was nothing to do
   other than to simply take the 'net-next' hunks.

Daniele Palmas 9bd813da24 NET: usb: qmi_wwan: add support for Telit LE922A PID 0x1040
This patch adds support for PID 0x1040 of Telit LE922A.

The qmi adapter requires to have DTR set for proper working,
so QMI_WWAN_QUIRK_DTR has been enabled.

Kristian Evensen d5c83d0d1d cdc_ether: Fix handling connection notification
Commit bfe9b9d2df ("cdc_ether: Improve ZTE MF823/831/910 handling")
introduced a work-around in usbnet_cdc_status() for devices that exported
cdc carrier on twice on connect. Before the commit, this behavior caused
the link state to be incorrect. It was assumed that all CDC Ethernet
devices would either export this behavior, or send one off and then one on
notification (which seems to be the default behavior).

Unfortunately, it turns out multiple devices sends a connection
notification multiple times per second (via an interrupt), even when
connection state does not change. This has been observed with several
different USB LAN dongles (at least), for example 13b1:0041 (Linksys).
After bfe9b9d2df, the link state has been set as down and then up for
each notification. This has caused a flood of Netlink NEWLINK messages and
syslog to be flooded with messages similar to:

cdc_ether 2-1:2.0 eth1: kevent 12 may have been dropped

This commit fixes the behavior by reverting usbnet_cdc_status() to how it
was before bfe9b9d2df. The work-around has been moved to a separate
status-function which is only called when a known, affect device is
detected.

v1->v2:

* Do not open-code netif_carrier_ok() (thanks Henning Schild).
* Call netif_carrier_off() instead of usb_link_change(). This prevents
calling schedule_work() twice without giving the work queue a chance to be
processed (thanks Bjørn Mork).
