Pull kbuild updates from Michal Marek:
- EXPORT_SYMBOL for asm source by Al Viro.
This does bring a regression, because genksyms no longer generates
checksums for these symbols (CONFIG_MODVERSIONS). Nick Piggin is
working on a patch to fix this.
Plus, we are talking about functions like strcpy(), which rarely
change prototypes.
- Fixes for PPC fallout of the above by Stephen Rothwell and Nick
Piggin
- fixdep speedup by Alexey Dobriyan.
- preparatory work by Nick Piggin to allow architectures to build with
-ffunction-sections, -fdata-sections and --gc-sections
- CONFIG_THIN_ARCHIVES support by Stephen Rothwell
- fix for filenames with colons in the initramfs source by me.
* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: (22 commits)

Pull thermal managament updates from Zhang Rui:
- Enhance thermal "userspace" governor to export the reason when a
thermal event is triggered and delivered to user space. From Srinivas
Pandruvada
- Introduce a single TSENS thermal driver for the different versions of
the TSENS IP that exist, on different qcom msm/apq SoCs'. Support for
msm8916, msm8960, msm8974 and msm8996 families is also added. From
Rajendra Nayak
- Introduce hardware-tracked trip points support to the device tree
thermal sensor framework. The framework supports an arbitrary number
of trip points. Whenever the current temperature is changed, the trip
points immediately below and above the current temperature are found,
driver callback is invoked to program the hardware to get notified
when either of the two trip points are triggered. Hardware-tracked
trip points support for rockchip thermal driver is also added at the
same time. From Sascha Hauer, Caesar Wang
- Introduce a new thermal driver, which enables TMU (Thermal Monitor
Unit) on QorIQ platform. From Jia Hongtao
- Introduce a new thermal driver for Maxim MAX77620. From Laxman
Dewangan
- Introduce a new thermal driver for Intel platforms using WhiskeyCove
PMIC. From Bin Gao

because the top Makefile forces to include it with:
-include $(srctree)/include/linux/kconfig.h
This commit removes explicit includes except the following:

* tools/testing/radix-tree/linux/kernel.h
These two are used for host programs.

Currently, all callers to randomize_range() set the length to 0 and
calculate end by adding a constant to the start address. We can simplify
the API to remove a bunch of needless checks and variables.
Use the new randomize_addr(start, range) call to set the requested
address.

These updates have been kept in a separate branch mostly because
they rely on updates to the respective clk drivers to keep the
shared header files in sync.
- The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
automotive SoC similar to the ⅹ8a7795 chip we already support, but
the dts changes rely on a clock driver change that has been
merged for v4.9 through the clk tree.
- The Amlogic meson-gxbb (S905) platform gains support for a few
drivers merged through our tree, in particular the network and
usb driver changes are required and included here, and also
the clk tree changes.
- The Allwinner platforms have seen a large-scale change to their
clk drivers and the dts file updates must come after that.
This includes the newly added Nextthing GR8 platform, which is
derived from sun5i/A13.
- Some integrator (arm32) changes rely on clk driver changes.
- A single patch for lpc32xx has no such dependency but wasn't
added until just before the merge window

These are as usual a very large number of mostly boring updates to
enable devices in existing machines, or to fix minor bugs. Notably,
an ongoing treewide effort to fix warnings caused by an update to the
device tree compiler. These are enabled with "make W=1" at the moment
but can hopefully become the default once all issues have been addressed.

Pull ARM DT updates from Arnd Bergmann:
"These are as usual a very large number of mostly boring updates to
enable devices in existing machines, or to fix minor bugs. Notably, an
ongoing treewide effort to fix warnings caused by an update to the
device tree compiler. These are enabled with "make W=1" at the moment
but can hopefully become the default once all issues have been
addressed.
No new SoC platform is added this time around (Armada 395 and Orion
mv88f5181 are slight variations of existing ones), but a significant
number of new dts files are added, which I list by platform:
- Allwinner: Empire Electronix M712 and iNet d978 Rev2 tablets,
Orange Pi PC Plus, Orange Pi 2, Orange Pi Plus 2E, Orange Pi Lite,
Olimex A33-Olinuxino, and Nano Pi Neo single-board computers

- We get support for running in big-endian mode on two platforms:
sunxi (Allwinner) and s3c24xx (old Samsung).
- The recently added Uniphier platform now uses standard PSCI
methods for SMP booting and we remove support for old bootloader
versions that did not support it yet.
- In sunxi, we gain support for the "Nextthing GR8" SoC, which
is a close relative of the Allwinner A13 and R8 chips.
- PXA completes its move over to the generic dmaengine framework
and removes its old private API
- mach-bcm gains support for BCM47189/BCM53573, their first ARM
SoC with integrated 802.11ac wireless networking.

The cleanups for v4.9 are a little larger that usual, but thankfully
that is almost exclusively due to removing a significant number of
files that have become obsolete after the still ongoing conversion
of old board files to devicetree.
- for mach-omap2, which is still the largest platform in arch/arm/,
the conversion to DT is finally complete after the Nokia N900 is
now fully supported there, along with the omap3 LDP, and we can
remove those two board files.
If no regressions are found, another large cleanup for the platform
will happen as a follow-up, removing dead code and restructuring
the platform based on being DT-only.
- In mach-imx, similar work is ongoing, but has not come that far.
This time, we remove the obsolete board file for the i.MX1
generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only.
The remaining board files are for i.MX2 and i.MX3 machines
based on old ARM926 or ARM1136 cores that should work with DT
in principle.
- realview has just been converted from board files to DT, and a lot
of code gets removed in the process. This is the last
ARM/Keil/Versatile derived platform that was still using board
files, the other ones being integrator, versatile and vexpress.
We can probably merge the remaining code into a single directory
in the near future.
- clps711x had completed the conversion in v4.8, but we accidentally
left the files in place that should have been deleted then.
Conflicts: two files deleted here have been modified upstream,
the changes can be discarded.

When doing an nmi backtrace of many cores, most of which are idle, the
output is a little overwhelming and very uninformative. Suppress
messages for cpus that are idling when they are interrupted and just
emit one line, "NMI backtrace for N skipped: idling at pc 0xNNN".
We do this by grouping all the cpuidle code together into a new
.cpuidle.text section, and then checking the address of the interrupted
PC to see if it lies within that section.
This commit suitably tags x86 and tile idle routines, and only adds in
the minimal framework for other architectures.

Currently on arm there is code that checks whether it should call
dump_stack() explicitly, to avoid trying to raise an NMI when the
current context is not preemptible by the backtrace IPI. Similarly, the
forthcoming arch/tile support uses an IPI mechanism that does not
support generating an NMI to self.
Accordingly, move the code that guards this case into the generic
mechanism, and invoke it unconditionally whenever we want a backtrace of
the current cpu. It seems plausible that in all cases, dump_stack()
will generate better information than generating a stack from the NMI
handler. The register state will be missing, but that state is likely
not particularly helpful in any case.
Or, if we think it is helpful, we should be capturing and emitting the
current register state in all cases when regs == NULL is passed to
nmi_cpu_backtrace().

Patch series "improvements to the nmi_backtrace code" v9.
This patch series modifies the trigger_xxx_backtrace() NMI-based remote
backtracing code to make it more flexible, and makes a few small
improvements along the way.
The motivation comes from the task isolation code, where there are
scenarios where we want to be able to diagnose a case where some cpu is
about to interrupt a task-isolated cpu. It can be helpful to see both
where the interrupting cpu is, and also an approximation of where the
cpu that is being interrupted is. The nmi_backtrace framework allows us
to discover the stack of the interrupted cpu.
I've tested that the change works as desired on tile, and build-tested
x86, arm, mips, and sparc64. For x86 I confirmed that the generic
cpuidle stuff as well as the architecture-specific routines are in the
new cpuidle section. For arm, mips, and sparc I just build-tested it
and made sure the generic cpuidle routines were in the new cpuidle
section, but I didn't attempt to figure out which the platform-specific
idle routines might be. That might be more usefully done by someone
with platform experience in follow-up patches.
This patch (of 4):
Currently you can only request a backtrace of either all cpus, or all
cpus but yourself. It can also be helpful to request a remote backtrace
of a single cpu, and since we want that, the logical extension is to
support a cpumask as the underlying primitive.
This change modifies the existing lib/nmi_backtrace.c code to take a
cpumask as its basic primitive, and modifies the linux/nmi.h code to use
the new "cpumask" method instead.
The existing clients of nmi_backtrace (arm and x86) are converted to
using the new cpumask approach in this change.
The other users of the backtracing API (sparc64 and mips) are converted
to use the cpumask approach rather than the all/allbutself approach.
The mips code ignored the "include_self" boolean but with this change it
will now also dump a local backtrace if requested.

This came to light when implementing native 64-bit atomics for ARCv2.
The atomic64 self-test code uses CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE
to check whether atomic64_dec_if_positive() is available. It seems it
was needed when not every arch defined it. However as of current code
the Kconfig option seems needless
- for CONFIG_GENERIC_ATOMIC64 it is auto-enabled in lib/Kconfig and a
generic definition of API is present lib/atomic64.c
- arches with native 64-bit atomics select it in arch/*/Kconfig and
define the API in their headers
So I see no point in keeping the Kconfig option
Compile tested for:
- blackfin (CONFIG_GENERIC_ATOMIC64)
- x86 (!CONFIG_GENERIC_ATOMIC64)
- ia64

register a callback_result which tells them the result of the dma
transaction. Right now only one user ntb is using it.
- As we discussed on KS mailing list and pointed out NO_IRQ has no place in

- Correct ARMs dma-mapping to use the correct printk format strings.
- Avoid defining OBJCOPYFLAGS globally which upsets lkdtm rodata
testing.
- Cleanups to ARMs asm/memory.h include.
- L2 cache cleanups.
- Allow flat nommu binaries to be executed on ARM MMU systems.
- Kernel hardening - add more read-only after init annotations,
including making some kernel vdso variables const.
- Ensure AMBA primecell clocks are appropriately defaulted.
- ARM breakpoint cleanup.
- Various StrongARM 11x0 and companion chip (SA1111) updates to bring
this legacy platform to use more modern APIs for (eg) GPIOs and
interrupts, which will allow us in the future to reduce some of the
board-level driver clutter and elimate function callbacks into board
code via platform data. There still appears to be interest in these
platforms!
- Remove the now redundant secure_flush_area() API.
- Module PLT relocation optimisations. Ard says: This series of 4
patches optimizes the ARM PLT generation code that is invoked at
module load time, to get rid of the O(n^2) algorithm that results in
pathological load times of 10 seconds or more for large modules on

"A 5% error in delay calculation was introduced during the last merge
window, which had gone un-noticed until yesterday"
* 'fixes' of git://git.armlinux.org.uk/~rmk/linux-arm:
ARM: fix delays
Commit 215e362daf ("ARM: 8306/1: loop_udelay: remove bogomips value
limitation") tried to increase the bogomips limitation, but in doing
so messed up udelay such that it always gives about a 5% error in the
delay, even if we use a timer.
The calculation is:
loops = UDELAY_MULT * us_delay * ticks_per_jiffy >> UDELAY_SHIFT
Originally, UDELAY_MULT was ((UL(2199023) * HZ) >> 11) and UDELAY_SHIFT
30. Assuming HZ=100, us_delay of 1000 and ticks_per_jiffy of 1660000
(eg, 166MHz timer, 1ms delay) this would calculate:
((UL(2199023) * HZ) >> 11) * 1000 * 1660000 >> 30
=> 165999
With the new values of 2047 * HZ + 483648 * HZ / 1000000 and 31, we get:
(2047 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31
=> 158269
which is incorrect. This is due to a typo - correcting it gives:
(2147 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31
=> 165999
i.o.w, the original value.

...
Subsystem improvements:
- Do away with the last users of the obsolete Kconfig options
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
always sounded like an item on a wishlist to Santa Claus to
me). We can now select GPIOLIB and be done with it, for all
archs. After some struggle it even work on UM. Not that it has
GPIO, but if it wants to, it can select the library.
- Continued efforts to make drivers properly either tristate or
bool.
- Introduce a warning for drivers assigning default triggers to
their irqchip lines when probed from device tree, so we find and
fix these ambigous drivers. It is agreed that in the OF config
path, the device tree defines trigger characteristics.
- The same warning, mutatis mutandis, for ACPI-probed GPIO
irqchips.
- We introduce the ability to mark certain IRQ lines as "unusable"
as they can be taken by BIOS/firmware, unrouted in silicon and
generally nasty if you use them, and such things. This is
put to good use in the STMPE driver and also in the Cherryview
pin control driver.
- A new "mockup" virtual GPIO device that can be used for testing.
The plan is to add unit tests under tools/* for exercising this
device and verify that the kernel code paths are working as they
should.
- Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
implicit all the time, but when people started building UM
with allyesconfig or allmodconfig it exploded in their face.
- Move some stray bits of device tree and ACPI HW description
callbacks down into their respective implementation silo. These
were causing issues when compiling on !HAS_IOMEM as well, so
now eventually UM compiles the GPIOLIB library if it wants to.
New drivers:
- New driver for the Aspeed GPIO front-end companion to the
pin controller merged through the pin control tree.
- New driver for the LP873x PMIC GPIO portions.
- New driver for Technologic Systems' I2C FPGA GPIO such as
TS4900, TS-7970, TS-7990 and TS-4100.
- New driver for the Broadcom BCM63xx series including BCM6338
and BCM6345.
- New driver for the Intel WhiskeyCove PMIC GPIO.
- New driver for the Allwinner AXP209 PMIC GPIO portions.
- New driver for Diamond Systems 48 line GPIO-MM, another of
these port-mapped I/O expansion cards.
- Support the STMicroelectronics STMPE1600 variant in the STMPE
driver.
Driver improvements:
- The STMPE driver now supports rising/falling edge detection
properly for IRQs.
- The PCA954x will now fetch and enable its VCC regulator properly.
- Major rework of the PCA953x driver with the goal of eventually
switching it over to use regmap and thus modernize it even more.
- Switch the IOP driver to use the generic MMIO GPIO library.
- Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
over to this subsystem from MFD, achieveing some separation of
concerns.

that weren't causing enough problems (or any problems when we're just
clarifying things) to warrant sending outside the merge window. The
majority of changes are in drivers for various SoCs. Full details
are in the logs, but here's the summary.
Core:
- Better support for DeviceTree overlays with the addition of the
CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver
for a device node that matched during of_clk_init(), unless
the driver uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE.
This allows overlays to work cleanly for drivers that must probe
before the device model is ready, and also after it's ready
when an overlay is loaded.
- Clarification in the code around how clk_hw pointers are returned
from of clk providers
- Proper migration of prepare/enable counts to parents when the
clk tree is constructed
New Drivers:
- Socionext's UniPhier SoCs
- Loongson1C
- ZTE ZX296718
- Qualcomm MDM9615
- Amlogic GXBB AO clocks and resets
- Broadcom BCM53573 ILP
- Maxim MAX77620
Updates:
- Four Allwinner SoCs are migrated to the new style clk driver (A31, A31s,
A23 and A33)
- Exynos 5xxx audio and DRAM clks
- Loongson1B AC97, DMA and NAND clks
- Rockchip DDR clks and rk3399 driver tweaks
- Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer clks
- Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W
- Amlogic GXBB MMC gate clks
- at91 sama5d4 sckc
- Removal of STiH415 and STiH416 clk support as the SoC is being removed

Lots of little things here, all over the driver tree for subsystems that
flow through me. Nothing major that I can discern, full details are in

Pull CPU hotplug updates from Thomas Gleixner:
"Yet another batch of cpu hotplug core updates and conversions:
- Provide core infrastructure for multi instance drivers so the
drivers do not have to keep custom lists.
- Convert custom lists to the new infrastructure. The block-mq custom
list conversion comes through the block tree and makes the diffstat
tip over to more lines removed than added.
- Handle unbalanced hotplug enable/disable calls more gracefully.
- Remove the obsolete CPU_STARTING/DYING notifier support.
- Convert another batch of notifier users.
The relayfs changes which conflicted with the conversion have been
shipped to me by Andrew.
The remaining lot is targeted for 4.10 so that we finally can remove
the rest of the notifiers"

"The irq departement proudly presents:
- A rework of the core infrastructure to optimally spread interrupt

failed to take thread siblings and other details into account.
Developed in cooperation with Christoph and Keith.
- Proper delegation of softirqs to ksoftirqd, so if ksoftirqd is
active then no further softirq processsing on interrupt return
happens. Otherwise we try to delegate and still run another batch
of network packets in the irq return path, which then tries to
delegate to ksoftirqd .....
- A proper machine parseable sysfs based alternative for
/proc/interrupts.
- ACPI support for the GICV3-ITS and ARM interrupt remapping

Pull power management updates from Rafael Wysocki:
"Traditionally, cpufreq is the area with the greatest number of
changes, but there are fewer of them than last time. There also is
some activity in the generic power domains and the devfreq frameworks,
a couple of system suspend and hibernation fixes and some assorted
changes in other places.
One new feature is the cpufreq change to allow the scheduler to pass
hints to the governors' utilization update callbacks and some code
rework based on that. Another one is the support for domain removal in
the generic power domains framework. Also it is now possible to use
hibernation with PAGE_POISONING_ZERO enabled and devfreq supports the
RockChip DFI controller and the rk3399 DMC.
The rest of the changes is mostly fixes and cleanups in a number of
places.
Specifics:
- Add a mechanism for passing hints from the scheduler to cpufreq
governors via their utilization update callbacks and use it to
introduce "IOwait boosting" into the schedutil governor and
intel_pstate that will make them boost performance if the enqueued
task was previously waiting on I/O (Rafael Wysocki).

The change adds a new device node with description of generic SRAM
on-chip memory found on NXP LPC32xx SoC series and connected to AHB
matrix slave port 3.
Note that NXP LPC3220 SoC has 128KiB of SRAM memory, the other
LPC3230, LPC3240 and LPC3250 SoCs all have 256KiB SRAM space,
in the shared DTSI file this change specifies 128KiB SRAM size.
Also it's worth to mention that the SRAM area contains of 64KiB banks,
2 banks on LPC3220 and 4 banks on the other SoCs from the series, and
all SRAM banks but the first one have independent power controls,
the description of this feature will be added with the introduction of
power domains for the SoC series.

wrongly, by adding the PFN offset of memory twice.
- A fix from Robin to correct parsing of MPIDR values when the
address size is larger than one BE32 unit.
- A fix from Srinivas to ensure that we do not rely on the boot
loader (or previous Linux kernel) setting the translation table
base register a certain way in the decompressor, which can lead to
crashes"

ARM: 8616/1: dt: Respect property size when parsing CPUs
If the bootloader uses the long descriptor format and jumps to
kernel decompressor code, TTBCR may not be in a right state.
Before enabling the MMU, it is required to clear the TTBCR.PD0
field to use TTBR0 for translation table walks.
The commit dbece45894 ("ARM: 7501/1: decompressor:
reset ttbcr for VMSA ARMv7 cores") does the reset of TTBCR.N, but
doesn't consider all the bits for the size of TTBCR.N.
Clear TTBCR.PD0 field and reset all the three bits of TTBCR.N to
indicate the use of TTBR0 and the correct base address width.
