Some drivers (sierra_net) need the status interrupt URB
active even when the device is closed, because they receive
custom indications from firmware. Add functions to refcount
the status interrupt URB submit/kill operation so that
sub-drivers and the generic driver don't fight over whether
the status interrupt URB is active or not.
A sub-driver can call usbnet_status_start() at any time, but
the URB is only submitted the first time the function is
called. Likewise, when the sub-driver is done with the URB,
it calls usbnet_status_stop() but the URB is only killed when
all users have stopped it. The URB is still killed and
re-submitted for suspend/resume, as before, with the same
refcount it had at suspend.

A rebranded Novatel E371 for AT&T's LTE bands. qmi_wwan should drive this
device, while cdc_ether should ignore it. Even though the USB descriptors
are plain CDC-ETHER that USB interface is a QMI interface.

be_close() followed by be_clear() is called as a part of cleanup in the
EEH/AER flow. This patch stops TX in be_close() before cleaning/freeing
up the TX queues in be_clear(). This prevents be_xmit() from being called
while TX queues no longer exist.

While cleaning RX queues, the CQ DB may be rung several times (with rearm)
while waiting for the flush compl. Each CQ-notify with rearm can result in
an event. The EQ may get full resulting in a HW error.
Fix this by not re-arming the CQ while notifying a valid completion.
Also, there's no need to wait for 1ms after destroying RXQ, as the code in
be_rx_cq_clean() waits for the flush compl to arrive.

The buffer size for a FW cmd request must be big enough to fit the response,
else the cmd fails. For GET_MAC_LIST cmd, though the memory allocated for
the cmd is big enough to fit the response, the payload_len value in the
WRB hdr is being set to the request length only.
Fix this for GET_MAC_LIST cmd.

When the PF driver calls pci_enable_sriov(), the VFs may be probed
inline before the call returns. So, the resources required for all VFs
must be provisioned by the PF driver *before* calling pci_enable_sriov();
else, VF probe will fail.

git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc
Pull remoteproc update from Ohad Ben-Cohen:
- Some refactoring, cleanups and small improvements from Sjur
Brændeland. The improvements are mainly about better supporting
varios virtio properties (such as virtio's config space, status and
features). I now see that I messed up while commiting one of Sjur's
patches and erroneously put myself as the author, as well as letting
a nasty typo sneak in. I will not fix this in order to avoid
rebasing the patches. Sjur - sorry!
- A new remoteproc driver for OMAP-L13x (technically a DaVinci
platform) from Robert Tivy.
- Extend OMAP support to OMAP5 as well, from Vincent Stehlé.

Pull late ARM Exynos multiplatform changes from Arnd Bergmann:
"These continue the multiplatform support for exynos, adding support
for building most of the essential drivers (clocksource, clk, irqchip)
when combined with other platforms. As a result, it should become
really easy to add full multiplatform exynos support in 3.11, although
we don't yet enable it for 3.10.
The changes were not included in the earlier multiplatform series in
order to avoid clashes with the other Exynos updates.
This also includes work from Tomasz Figa to fix the pwm clocksource
code on Exynos, which is not strictly required for multiplatform, but
related to the other patches in this set and needed as a bug fix for
at least one board."

Pull ARM SoC late cleanups from Arnd Bergmann:
"These are cleanups and smaller changes that either depend on earlier
feature branches or came in late during the development cycle. We
normally try to get all cleanups early, so these are the exceptions:
- A follow-up on the clocksource reworks, hopefully the last time we
need to merge clocksource subsystem changes through arm-soc.
A first set of patches was part of the original 3.10 arm-soc
cleanup series because of interdependencies with timer drivers now
moved out of arch/arm.
- Migrating the SPEAr13xx platform away from using auxdata for DMA
channel descriptions towards using information in device tree,
based on the earlier SPEAr multiplatform series
- A few follow-ups on the Atmel SAMA5 support and other changes for
Atmel at91 based on the larger at91 reworks.
- Moving the armada irqchip implementation to drivers/irqchip
- Several OMAP cleanups following up on the larger series already
merged in 3.10."

Pull ARM SoC platform updates (part 3) from Arnd Bergmann:
"This is the third and smallest of the SoC specific updates. Changes
include:
- SMP support for the Xilinx zynq platform
- Smaller imx changes
- LPAE support for mvebu
- Moving the orion5x, kirkwood, dove and mvebu platforms to a common
"mbus" driver for their internal devices.
It would be good to get feedback on the location of the "mbus" driver.
Since this is used on multiple platforms may potentially get shared
with other architectures (powerpc and arm64), it was moved to
drivers/bus/. We expect other similar drivers to get moved to the
same place in order to avoid creating more top-level directories under
drivers/ or cluttering up the messy drivers/misc/ even more."

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates (part 2) from Arnd Bergmann:
"These patches are all for Renesas shmobile, and depend on the earlier
pinctrl updates. Remarkably, this adds support for three new SoCs:
r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is
for pinctrl (using the new subsystem) and for clocks (not yet using
the common clock subsystem). The latter will have to get converted in
one of the upcoming releases, but shmobile is not ready for that yet.
The series also contains Renesas shmobile board changes, adding one
board file for each of the three new SoCs. These boards are using a
mix of classic and device-tree based probing, as there is still a lot
of infrastructure in shmobile that has not been converted to DT yet.
Once those are resolved to the degree that no board specific setup
code is needed, they can get folded into the respective SoC setup files."

Pull Ceph changes from Alex Elder:
"This is a big pull.
Most of it is culmination of Alex's work to implement RBD image
layering, which is now complete (yay!).
There is also some work from Yan to fix i_mutex behavior surrounding
writes in cephfs, a sync write fix, a fix for RBD images that get
resized while they are mapped, and a few patches from me that resolve
annoying auth warnings and fix several bugs in the ceph auth code."

When unloading the driver that drives an EISA board, a message similar to the
following one is displayed:
Trying to free nonexistent resource <0000000000013000-000000000001301f>
Then an user is unable to reload the driver because the resource it requested in
the previous load hasn't been freed. This happens most probably due to a typo in
vortex_eisa_remove() which calls release_region() with 'dev->base_addr' instead
of 'edev->base_addr'...

Pull MFD update from Samuel Ortiz:
"For 3.10 we have a few new MFD drivers for:
- The ChromeOS embedded controller which provides keyboard, battery
and power management services. This controller is accessible
through i2c or SPI.
- Silicon Laboratories 476x controller, providing access to their FM
chipset and their audio codec.
- Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based
reader.
- Nokia's Tahvo power button and watchdog device. This device is
very similar to Retu and is thus supported by the same code base.
- STMicroelectronics STMPE1801, a keyboard and GPIO controller
supported by the stmpe driver.
- ST-Ericsson AB8540 and AB8505 power management and voltage
converter controllers through the existing ab8500 code.
Some other drivers got cleaned up or improved. In particular:
- The Linaro/STE guys got the ab8500 driver in sync with their
internal code through a series of optimizations, fixes and
improvements.
- The AS3711 and OMAP USB drivers now have DT support.
- The arizona clock and interrupt handling code got improved.
- The wm5102 register patch and boot mechanism also got improved."

Some ancient pHyp versions used to create a 8 bytes local-mac-address
property in the device-tree instead of a 6 bytes one for veth.
The Linux driver code to deal with that is an insane hack which also
happens to break with some choices of MAC addresses in qemu by testing
for a bit in the address rather than just looking at the size of the
property.
Sanitize this by doing the latter instead.

Pull single_open() leak fixes from Al Viro:
"A bunch of fixes for a moderately common class of bugs: file with
single_open() done by its ->open() and seq_release as its ->release().
That leaks; fortunately, it's not _too_ common (either people manage
to RTFM that says "When using single_open(), the programmer should use
single_release() instead of seq_release() in the file_operations
structure to avoid a memory leak", or they just copy a correct
instance), but grepping through the tree has caught quite a pile.
All of that is, AFAICS, -stable fodder, for as far as the patches
apply. I tried to carve it up into reasonably-sized pieces (more or
less "comes from the same tree")"
