Pull ACPI and power management updates from Rafael Wysocki:
"Features-wise, to me the most important this time is a rework of
wakeup interrupts handling in the core that makes them work
consistently across all of the available sleep states, including
suspend-to-idle. Many thanks to Thomas Gleixner for his help with
this work.
Second is an update of the generic PM domains code that has been in
need of some care for quite a while. Unused code is being removed, DT
support is being added and domains are now going to be attached to
devices in bus type code in analogy with the ACPI PM domain. The
majority of work here was done by Ulf Hansson who also has been the
most active developer this time.
Apart from this we have a traditional ACPICA update, this time to
upstream version 20140828 and a few ACPI wakeup interrupts handling
patches on top of the general rework mentioned above. There also are
several cpufreq commits including renaming the cpufreq-cpu0 driver to
cpufreq-dt, as this is what implements generic DT-based cpufreq
support, and a new DT-based idle states infrastructure for cpuidle.
In addition to that, the ACPI LPSS driver is updated, ACPI support for
Apple machines is improved, a few bugs are fixed and a few cleanups
are made all over.
Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
maintained by Kevin Hilman that will be merged through the PM tree.
Numbers-wise, the generic PM domains update takes the lead this time
with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
place goes to the wakeup interrupts handling rework (13 commits).
Specifics:
- Rework the handling of wakeup IRQs by the IRQ core such that all of
them will be switched over to "wakeup" mode in suspend_device_irqs()
and in that mode the first interrupt will abort system suspend in
progress or wake up the system if already in suspend-to-idle (or
equivalent) without executing any interrupt handlers. Among other
things that eliminates the wakeup-related motivation to use the
IRQF_NO_SUSPEND interrupt flag with interrupts which don't really
need it and should not use it (Thomas Gleixner and Rafael Wysocki)
- Switch over ACPI to handling wakeup interrupts with the help of the
new mechanism introduced by the above IRQ core rework (Rafael Wysocki)
- Rework the core generic PM domains code to eliminate code that's
not used, add DT support and add a generic mechanism by which
devices can be added to PM domains automatically during enumeration
(Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
- Add debugfs-based mechanics for debugging generic PM domains
(Maciej Matraszek).
- ACPICA update to upstream version 20140828. Included are updates
related to the SRAT and GTDT tables and the _PSx methods are in the
METHOD_NAME list now (Bob Moore and Hanjun Guo).
- Add _OSI("Darwin") support to the ACPI core (unfortunately, that
can't really be done in a straightforward way) to prevent
Thunderbolt from being turned off on Apple systems after boot (or
after resume from system suspend) and rework the ACPI Smart Battery
Subsystem (SBS) driver to work correctly with Apple platforms
(Matthew Garrett and Andreas Noever).
- ACPI LPSS (Low-Power Subsystem) driver update cleaning up the code,
adding support for 133MHz I2C source clock on Intel Baytrail to it
and making it avoid using UART RTS override with Auto Flow Control
(Heikki Krogerus).
- ACPI backlight updates removing the video_set_use_native_backlight
quirk which is not necessary any more, making the code check the
list of output devices returned by the _DOD method to avoid
creating acpi_video interfaces that won't work and adding a quirk
for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak)
- New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin)
- Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
Sudip Mukherjee, Yijing Wang, and Zhang Rui)
- cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
Rasmus Villemoes)
- cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name change
among other things), ppc-corenet, powernv (Viresh Kumar, Preeti U
Murthy, Shilpasri G Bhat, Lucas Stach)
- cpuidle support for DT-based idle states infrastructure, new ARM64
cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi, Rasmus
Villemoes)
- ARM big.LITTLE cpuidle driver updates: support for DT-based
initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
Kevin Hilman)
- Rework of the test_suspend kernel command line argument and a new
trace event for console resume (Srinivas Pandruvada, Todd E Brandt)
- Second attempt to optimize swsusp_free() (hibernation core) to make
it avoid going through all PFNs which may be way too slow on some
systems (Joerg Roedel)
- devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
- rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS entry
update in MAINTAINERS (Heiko Stübner, Kevin Hilman)
- PM core fix related to clock management (Geert Uytterhoeven)
- PM core's sysfs code cleanup (Johannes Berg)"

Pull GPIO changes from Linus Walleij:
"This is the bulk of GPIO changes for the v3.18 development cycle:
- Increase the default ARCH_NR_GPIO from 256 to 512. This was done
to avoid having a custom <asm/gpio.h> header for the x86
architecture - GPIO is custom and complicated enough as it is
already! We want to move to a radix to store the descriptors going
forward, and finally get rid of this fixed array size altogether.
- Endgame patching of the gpio_remove() semantics initiated by
Abdoulaye Berthe. It is not accepted by the system that the
removal of a GPIO chip fails during eg reboot or shutdown, and
therefore the return value has now painfully been refactored away.
For special cases like GPIO expanders on a hot-pluggable bus like
USB, we may later add some gpiochip_try_remove() call, but for the
cases we have now, return values are moot.
- Some incremental refactoring of the gpiolib core and ACPI GPIO
library for more descriptor usage.
- Refactor the chained IRQ handler set-up method to handle also
threaded, nested interrupts and set up the parent IRQ correctly.
Switch STMPE and TC3589x drivers to use this registration method.
- Add a .irq_not_threaded flag to the struct gpio_chip, so that also
GPIO expanders that block but are still not using threaded IRQ
handlers.
- New drivers for the ARM64 X-Gene SoC GPIO controller.
- The syscon GPIO driver has been improved to handle the "DSP GPIO"
found on the TI Keystone 2 SoC:s.
- ADNP driver switched to use gpiolib irqchip helpers.
- Refactor the DWAPB driver to support being instantiated from and
MFD cell (platform device).
- Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP,
Xilinx and Crystalcove drivers.
- Various minor fixes"

Pull networking updates from David Miller:
"Most notable changes in here:
1) By far the biggest accomplishment, thanks to a large range of
contributors, is the addition of multi-send for transmit. This is
the result of discussions back in Chicago, and the hard work of
several individuals.
Now, when the ->ndo_start_xmit() method of a driver sees
skb->xmit_more as true, it can choose to defer the doorbell
telling the driver to start processing the new TX queue entires.
skb->xmit_more means that the generic networking is guaranteed to
call the driver immediately with another SKB to send.
There is logic added to the qdisc layer to dequeue multiple
packets at a time, and the handling mis-predicted offloads in
software is now done with no locks held.
Finally, pktgen is extended to have a "burst" parameter that can
be used to test a multi-send implementation.
Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
virtio_net
Adding support is almost trivial, so export more drivers to
support this optimization soon.
I want to thank, in no particular or implied order, Jesper
Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
David Tat, Hannes Frederic Sowa, and Rusty Russell.
2) PTP and timestamping support in bnx2x, from Michal Kalderon.
3) Allow adjusting the rx_copybreak threshold for a driver via
ethtool, and add rx_copybreak support to enic driver. From
Govindarajulu Varadarajan.
4) Significant enhancements to the generic PHY layer and the bcm7xxx
driver in particular (EEE support, auto power down, etc.) from
Florian Fainelli.
5) Allow raw buffers to be used for flow dissection, allowing drivers
to determine the optimal "linear pull" size for devices that DMA
into pools of pages. The objective is to get exactly the
necessary amount of headers into the linear SKB area pre-pulled,
but no more. The new interface drivers use is eth_get_headlen().
From WANG Cong, with driver conversions (several had their own
by-hand duplicated implementations) by Alexander Duyck and Eric
Dumazet.
6) Support checksumming more smoothly and efficiently for
encapsulations, and add "foo over UDP" facility. From Tom
Herbert.
7) Add Broadcom SF2 switch driver to DSA layer, from Florian
Fainelli.
8) eBPF now can load programs via a system call and has an extensive
testsuite. Alexei Starovoitov and Daniel Borkmann.
9) Major overhaul of the packet scheduler to use RCU in several major
areas such as the classifiers and rate estimators. From John
Fastabend.
10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
Duyck.

Pull ARM SoC cleanups from Arnd Bergmann:
"This time around, the cleanup branch contains mostly code removal. A
number of board files for at91, imx and msm have become obsolete
because of the DT conversion and are now ready to be removed. The
OMAP platform has traditionally had its own DMA engine abstraction and
as this is being phased out, a lot of the original code is now unused
and can be removed as well.
S3C24xx can be simplified now that the restart code is a proper device
driver.
Finally, a number of cleanups in shmobile are done to prepare for the
addition of new code in other branches"

- x86 has the usual emulator fixes and nested virtualization
improvements (including improved Windows support on Intel and
Jailhouse hypervisor support on AMD), adaptive PLE which helps
overcommitting of huge guests. Also included are some patches that
make KVM more friendly to memory hot-unplug, and fixes for rare

"Even though this has fixes marked for -stable, given the size and the
needed conflict resolutions this is 3.18-rc1/merge-window material.
These patches have been languishing in my tree for a long while. The
fact that I do not have the time to do proper/prompt maintenance of
this tree is a primary factor in the decision to step down as
dmaengine maintainer. That and the fact that the bulk of drivers/dma/
activity is going through Vinod these days.

conflicts against mainline and net-next (for-3.18).

Testing xmit_more support with netperf and connected UDP sockets,
I found strange dst refcount false sharing.
Current handling of IFF_XMIT_DST_RELEASE is not optimal.
Dropping dst in validate_xmit_skb() is certainly too late in case
packet was queued by cpu X but dequeued by cpu Y
The logical point to take care of drop/force is in __dev_queue_xmit()
before even taking qdisc lock.
As Julian Anastasov pointed out, need for skb_dst() might come from some
packet schedulers or classifiers.
This patch adds new helper to cleanly express needs of various drivers
or qdiscs/classifiers.
Drivers that need skb_dst() in their ndo_start_xmit() should call
following helper in their setup instead of the prior :
dev->priv_flags &= ~IFF_XMIT_DST_RELEASE;
->
netif_keep_dst(dev);
Instead of using a single bit, we use two bits, one being
eventually rebuilt in bonding/team drivers.
The other one, is permanent and blocks IFF_XMIT_DST_RELEASE being
rebuilt in bonding/team. Eventually, we could add something
smarter later.

Adjust fixed_phy_register() to return struct phy_device *, so that
it becomes easy to use fixed PHYs without device tree support:
phydev = fixed_phy_register(PHY_POLL, &fixed_phy_status, NULL);
fixed_phy_set_link_update(phydev, fixed_phy_link_update);
phy_connect_direct(netdev, phydev, handler_fn, phy_interface);
This change is a prerequisite for modifying bcmgenet driver to work
without a device tree on Broadcom's MIPS-based 7xxx platforms.

This removes the tcf_proto argument from the ematch code paths that
only need it to reference the net namespace. This allows simplifying
qdisc code paths especially when we need to tear down the ematch
from an RCU callback. In this case we can not guarentee that the
tcf_proto structure is still valid.

Some TSO engines might have a too heavy setup cost, that impacts
performance on hosts sending small bursts (2 MSS per packet).
This patch adds a device gso_min_segs, allowing drivers to set
a minimum segment size for TSO packets, according to the NIC
performance.
Tested on a mlx4 NIC, this allows to get a ~110% increase of
throughput when sending 2 MSS per packet.
