Christoffer Dall (KVM-ARM maintainer) says:
"There are a few changes in this pull request touching things
outside KVM, but they should all carry the necessary acks and it
made the merge process much easier to do it this way."
though actually the irqchip maintainers' acks didn't make it into the

We may need another patch to make them all ssize_t, but that

Pull ARC updates from Vineet Gupta:
"We have a relatively big changeset for ARC for 4.7.
The highlight is support for EZChip (now Mellanox) NPS-400 network
processor, a 400-Gb throughput C-programmable packet processor based
on ARC700 cores from Synopsys. See
http://www.mellanox.com/related-docs/prod_npu/PB_NPS-400.pdf
Also present are irqchip and clocksource drivers for NPS as agreed
with respective maintainers to go via ARC tree due to an soc header
dependency. I have the needed ACKs from Jason, Marc, Daniel. You
might run into a trivial merge conflict in drivers/irqchip/*
This EZChip platform support required some deep changes in ARC
architecture code and also opportunity to cleanup past sins (legacy
irq domains, missing irq domain lookup, hard coded timer irqs...)
Summary:
- Support for EZChip (now Mellanox) NPS-400 Network processor based
on ARC700
- NPS interrupt controller and clocksource drivers
- ARC timers probed off DT
- ARC iqrchips switching to linear domain (upgrade from legacy
domains)"

This patch adds binding information for IBM/AMCC/APM GPIO
Controllers of the PowerPC 4XX series and compatible SoCs.
The "PowerPC 405EP Embedded Processor Data Sheet" has the
following to say about the GPIO controllers: "
- Controller functions and GPIO registers are programmed
and accessed via memory-mapped OPB bus master accesses
- All GPIOs are pin-shared with other functions. DCRs control
whether a particular pin that has GPIO capabilities acts
as a GPIO or is used for another purpose.
- Each GPIO outputs is separately programmable to emulate
an open-drain driver (i.e. drives to zero, threestated if
output bit is 1)
"
The ppc4xx_gpio.c driver is part of the platform/sysdev drivers
in arch/powerpc/sysdev.

Function populate_node() is used to unflatten FDT blob to device
tree. It supports maximal 64 level of device nodes. There is one
array @fpsizes[64] tracking the full name length of last unflattened
device node in the corresponding level (index of element in the
array - 1). Build warning is seen with CONFIG_FRAME_WARN=1024 like
below on ARM64 as Geert reported. The issue can be reproduced on
PPC64 as well.
$ make drivers/of/fdt.o
drivers/of/fdt.c:443:1: warning: the frame size of 1136 bytes is \
larger than 1024 bytes [-Wframe-larger-than=]
This changes the data type of @fpsizes[i] from "unsigned long" to
"unsigned int" to avoid the build warning. The return value type
of populate_node() and its @fpsize argument is adjusted accordingly.
With this applied, 256 bytes saved from the stack frame on ARM64 and
PPC64 platforms and the above warning isn't seen.

When the implementation for unflatten_dt_node() changed from being
recursive to being non-recursive, it had a side effect of increasing the
depth passed to fdt_next_node() by 1. This is fine most of the time, but
it seems that when the end of the dtb is being parsed, it will cause the
FDT_END condition in fdt_next_node() to return a different value
(returning nextoffset instead of -FDT_ERR_NOTFOUND). This ends up passing
an FDT_ERR_TRUNCATED error back to the unflatten_dt_node() which then
sees that and complains "Error -8 processing FDT" causing boot to fail.
This patch simply avoids incrementing depth and uses modified accesses
for local array indices so that the depth is the same as it was before
the change as far as fdt_next_node() is concerned.
This problem was discovered trying to boot Tegra210-Smaug platforms.

On ARM64, the mtk-pmic-wrap driver causes a harmless warning:
mtk-pmic-wrap.c:1062:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
mtk-pmic-wrap.c:1074:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
mtk-pmic-wrap.c:1086:16: warning: large integer implicitly truncated to unsigned type [-Woverflow]
.int_en_all = ~(BIT(31) | BIT(1)),
The problem is that the result of the BIT() macro is an 'unsigned long',
so taking the bitwise NOT operation of that results in an integer
with the upper 32 bits all set and that cannot be assigned to a
'u32' variable without loss of information.
This is harmless because we were never interested in the upper bits
here anyway, so we can shut up the warning by adding a simple cast
to 'u32'.

With CONFIG_FRAME_POINTER enabled, a thunk can pass a bad return address
value to the called function. '9*8(%rsp)' actually gets the frame
pointer, not the return address.
The only users of the 'put_ret_addr_in_rdi' option are two functions
which trace the enabling and disabling of interrupts, so this bug can
result in bad debug or tracing information with CONFIG_IRQSOFF_TRACER or
CONFIG_PROVE_LOCKING.
Fix this by implementing the suggestion of Linus: explicitly push
the frame pointer all the time and constify the stack offsets that
way. This is both correct and easier to read.

Pull tracing updates from Steven Rostedt:
"This includes two new updates for the ftrace infrastructure.
- With the changing of the code for filtering events by pid, from a
list of pids to a bitmask, we can now easily implement following
forks. With a new tracing option "event-fork" which, when set,
will have tasks with pids in set_event_pid, when they fork, to have
their child pids added to set_event_pid and the child will be
traced as well.
Note, if "event-fork" is set and a task with its pid in
set_event_pid exits, its pid will be removed from set_event_pid
- The addition of Tom Zanussi's hist triggers. This includes a very
thorough documentatino on how to use the hist triggers with events.
This introduces a quick and easy way to get histogram data from
events and their fields.
Some other cleanups and updates were added as well. Like Masami
Hiramatsu added test cases for the event trigger and hist triggers.
Also I added a speed up of filtering by using a temp buffer when
filters are set"

Prefix print messages with KBUILD_MODNAME, i.e 'cpufreq_schedutil: '.
This helps to keep similar formatting for all the print messages
particular to a file and identify those easily in kernel logs.
Its already done this way for rest of the governors.
Along with that, remove the (now) redundant bits from a print message.

reasons.
For the most part, this is now related to power management

Pull ARM 64-bit DT updates from Arnd Bergmann:
"We continue ramping up platform support for 64-bit ARM machines, with
111 individual non-merge changesets touching 21 platforms.
The LG1312 platform is completely new and is the first ARM platform by
LG that we support in the mainline kernel. Two other SoCs got added
that are updated versions of existing SoC families, so the port mainly
consists of new dts files:
- The Hisilicon Hip06/D03 is the latest server platform from
Huawei/Hisilicon, and follows the Hip05/D02 platform.
- Rockchip RK3399 follows the 32-bit RK3288 that is popular in
low-end Chromebooks and the 64-bit RK3368 that is mainly found in
chinese Android TV boxes.
The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620) gets a
long-awaited overhaul with a lot of devices enabled in the DT, so it
should be much more usable with a mainline kernel now. See also
https://plus.google.com/111524780435806926688/posts/PeGb2VsNhJd

machines, but we also have a couple of new commercially available
machines:
- Google Pixel C laptop based on Tegra210
- Hardkernel Odroid C2 Based on Amlogic Meson GXBB (S905)
- Geekbuying GeekBox based on Rockchip RK3368

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Arnd Bergmann:
"We get support for three new 32-bit SoC platforms this time.
The amount of changes in arch/arm for any of them is miniscule, as all
the interesting code is in device driver subsystems (irqchip, clk,
pinctrl, ...) these days. I'm listing them here, as the addition of
the Kconfig statement is the main relevant milestone for a new
platform. In each case, some drivers are are shared with existing
platforms, while other drivers are added for v4.7 as well, or come in
a later release.
- The Aspeed platform is probably the most interesting one, this is
what most whitebox servers use as their baseboard management
controller. We get support for the very common ast2400 and ast2500
SoCs. The OpenBMC project focuses on this chip, and the LWN
article about their ELC 2016 presentation at
https://lwn.net/Articles/683320/
triggered the submission, but the code comes from IBM's OpenPOWER
team rather than the team at Facebook. There are still a lot more
drivers that need to get added over time, and I hope both teams can
work together on that.
- OXNAS is an old platform for Network Attached Storage devices from
Oxford Semiconductor. There are models with ARM10 (!) and
ARM11MPCore cores, but for now, we only support the original ARM9
based versions. The product lineup was subsequently part of PLX,
Avago and now the new Broadcom Ltd.
https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
has some more information.
- V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
cores and is related to the existing Realview / Versatile Express
lineup, but without MMU.
We now support various NOMMU platforms, so adding a new one is
fairly straightforward.
http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
has detailed information about the platform.
Other noteworthy updates:
- Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain
Lemieux are now maintaining the platform.
This is an older ARM9 based platform from NXP (not Freescale), but
it remains in use in embedded markets.
- Kevin Hilman is now co-maintaining the Amlogic Meson platform for
both 32-bit and 64-bit ARM, and started contributing some patches.
- As is often the case, work on the OMAP platforms makes up the bulk
of the actual SoC code changes in arch/arm, but there isn't a lot
of that either"

Pull s390 updates from Martin Schwidefsky:
"The s390 patches for the 4.7 merge window have the usual bug fixes and
cleanups, and the following new features:
- An interface for dasd driver to query if a volume is online to
another operating system
- A new ioctl for the dasd driver to verify the format for a range of
tracks
- Following the example of x86 the struct fpu is now allocated with
the task_struct
- The 'report_error' interface for the PCI bus to send an
adapter-error notification from user space to the service element
of the machine"

My laptop that uses the intel 7680 iwlwifi module would no longer
connects to the network. It would fail with a "Microcode SW error
detected." and spew out register state over and over again without ever
connecting to the network.
The cause is mis-merge in commit 909b27f70643, where David seems to have
lost some of the changes to iwl_mvm_set_tx_cmd() from commit
5c08b0f5026f ("iwlwifi: mvm: don't override the rate with the AMSDU
len").
The reason seems to be a conflict with commit d8fe484470dd ("iwlwifi:
mvm: add support for new TX CMD API"), which touched a line adjacent to
the changes in 909b27f70643.
David missed the fact that "info->driver_data[0]" had become
"skb_info->driver_data[0]". Then he removed the skb_info because it was
unused.
This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.

The distinction between PAGE_SIZE and PAGE_CACHE_SIZE was removed in
09cbfea mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release}
macros
The comments for the above functions described a distinction between
those, that is now redundant, so remove those paragraphs

In the truncate or hole-punch path in dax, we clear out sub-page ranges.
If these sub-page ranges are sector aligned and sized, we can do the
zeroing through the driver instead so that error-clearing is handled
automatically.
For sub-sector ranges, we still have to rely on clear_pmem and have the
possibility of tripping over errors.

This allows XFS to perform zeroing using the iomap infrastructure and
avoid buffer heads.
