0edaf86cf1 include/linux/nodemask.h: create next_node_in() helper 
Lots of code does

	node = next_node(node, XXX);
	if (node == MAX_NUMNODES)
		node = first_node(XXX);

so create next_node_in() to do this and use it in various places.

0139aa7b7f mm: rename _count, field of the struct page, to _refcount 
Many developers already know that field for reference count of the
struct page is _count and atomic type.  They would try to handle it
directly and this could break the purpose of page reference count
tracepoint.  To prevent direct _count modification, this patch rename it
to _refcount and add warning message on the code.  After that, developer
who need to handle reference count will find that field should not be
accessed directly.

4a5219edcd ARM: SoC driver updates for v4.7 
Driver updates for ARM SoCs, these contain various things that touch
 the drivers/ directory but got merged through arm-soc for practical
 reasons. For the most part, this is now related to power management
 controllers, which have not yet been abstracted into a separate
 subsystem, and typically require some code in drivers/soc or arch/arm
 to control the power domains.
 
 Another large chunk here is a rework of the NVIDIA Tegra USB3.0
 support, which was surprisingly tricky and took a long time to
 get done.
 
 Finally, reset controller handling as always gets merged through here
 as well.

9797f6b050 ARM: SoC defconfig updates for v4.7 
As usual, a bunch of commits, mostly adding drivers and other options to
 defconfigs.
 
 We are adding three new defconfig files for the newly added 32-bit
 machines (aspeed and mps2), the rest is mainly housekeeping.
 
 The changes outside of arch/arm/config/ are for a Kconfig symbol
 that got renamed.

2ec3240fd7 ARM: 64-bit DT updates for v4.7 
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
 
 A lot of work went into enabling new device drivers on existing
 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
 
 And finally, a couple of reference or development platforms
 that are not end-user platforms but are used for trying out
 the respective SoC platforms:
 
 - Amlogic Meson GXBB P200 and P201 development systems
 - NXP Layerscape 1043A QDS development board
 - Hisilicon Hip06 D03 server board, as mentioned above
 - LG1312 Reference Design

f7df9be067 ARM: DT updates for v4.7 
These are all the updates to device tree files for 32-bit platforms,
 which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
 changesets, 450 files changed, 23340 insertions, 5216 deletions.
 
 The three platforms that are added with the "soc" branch are here as well,
 and we add some related machine files:
 
 - For Aspeed AST2400/AST2500, we get the evaluation platform and
   the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
 - For Oxnas 810SE, the Western Digital "My Book World Edition"
   is added as the only platform at the moment.
 - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7)
   are supported
 
 On the ARM Realview development platform, we now support all machines
 with device tree, previously only the board files were supported, which
 in turn will likely be removed soon.
 
 Qualcomm IPQ4019 is the second generation ARM based "Internet Processor",

 "These are all the updates to device tree files for 32-bit platforms,
  which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
  changesets, 450 files changed, 23340 insertions, 5216 deletions.

  The three platforms that are added with the "soc" branch are here as
  well, and we add some related machine files:

   - For Aspeed AST2400/AST2500, we get the evaluation platform and the
     Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
   - For Oxnas 810SE, the Western Digital "My Book World Edition" is
     added as the only platform at the moment.
   - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7) are
     supported

  On the ARM Realview development platform, we now support all machines
  with device tree, previously only the board files were supported,
  which in turn will likely be removed soon.

  Qualcomm IPQ4019 is the second generation ARM based "Internet
  Processor", following the IPQ806x that is used in many high-end WiFi
  routers.  This one integrates two ath10k wifi radios that were
  previously on separate chips.

  Other boards that got added for existing chips are:

  Ti OMAP family:
     - Amazon Kindle Fire, first generation, tablet and ebook reader
     - OnRISC Baltos iR 2110 and 3220 embedded industrial PCs

9896c7b57e ARM: SoC platform updates for v4.7 
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.

f2b1e0f638 ARM: SoC cleanups and fixes for v4.7 
Traditionally we've had two separate branches for cleanups and non-critical
 bug fixes, but both of these got smaller with each release and the differences
 are rather unclear now, so it seems more appropriate to have a combined
 branch.
 
 The most notably change is for OMAP, which gets a small rework to simplify
 handling of the AUXDATA mechanism used on machines that are not completely
 DT based yet, along with other work that is used as preparation for dropping
 the legacy board files.

1eccc6e152 This is the bulk of GPIO changes for kernel cycle v4.7: 
Core infrastructural changes:
 
 - Support for natively single-ended GPIO driver stages. This
   means that if the hardware has registers to configure open
   drain or open source configuration, we use that rather than
   (as we did before) try to emulate it by switching the line
   to an input to get high impedance. This is also documented
   throughly in Documentation/gpio/driver.txt for those of you
   who did not understand one word of what I just wrote.
 
 - Start to do away with the unnecessarily complex and
   unitelligible ARCH_REQUIRE_GPIOLIB and
   ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
   the time when the GPIO subsystem was unmaintained. Archs can
   now just select GPIOLIB and be done with it, cleanups to
   arches will trickle in for the next kernel. Some minor archs
   ACKed the changes immediately so these are included in this
   pull request.
 
 - Advancing the use of the data pointer inside the GPIO device
   for storing driver data by switching the PowerPC, Super-H
   Unicore and a few other subarches or subsystem drivers in
   ALSA SoC, Input, serial, SSB, staging etc to use it.
 
 - The initialization now reads the input/output state of the
   GPIO lines, so that each GPIO descriptor knows - if this
   callback is implemented - whether the line is input or
   output. This also reflects nicely in userspace "lsgpio".
 
 - It is now possible to name GPIO producer names, line names,
   from the device tree. (Platform data has been supported for
   a while.) I bet we will get a similar mechanism for ACPI
   one of those days. This makes is possible to get sensible
   producer names for e.g. GPIO rails in "lsgpio" in userspace.
 
 New drivers:
 
 - New driver for the Loongson1.
 
 - The XLP driver now supports Broadcom Vulcan ARM64.
 
 - The IT87 driver now supports IT8620 and IT8628.
 
 - The PCA953X driver now supports Galileo Gen2.
 
 Driver improvements:
 
 - MCP23S08 was switched to use the gpiolib irqchip helpers and
   now also suppors level-triggered interrupts.
 
 - 74x164 and RCAR now supports the .set_multiple() callback
 
 - AMDPT was converted to use generic GPIO.
 
 - TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
   support the new single ended callback for open drain
   and in some cases open source.
 
 - Implement the .get_direction() callback for a few more drivers
   like PL061, Xgene.
 
 Cleanups:
 
 - Paul Gortmaker combed through the drivers and de-modularized
   those who are not really modules.
 
 - Move the GPIO poweroff DT bindings to the power subdir where
   they belong.
 
 - Rename gpio-generic.c to gpio-mmio.c, which is much more to the
   point. That's what it is handling, nothing more, nothing less.

4c1cd4fdfd bpf: arm64: remove callee-save registers use for tmp registers 
In the current implementation of ARM64 eBPF JIT, R23 and R24 are used for
tmp registers, which are callee-saved registers. This leads to variable size
of JIT prologue and epilogue. The latest blinding constant change prefers to
constant size of prologue and epilogue. AAPCS reserves R9 ~ R15 for temp
registers which not need to be saved/restored during function call. So, replace
R23 and R24 to R10 and R11, and remove tmp_used flag to save 2 instructions for
some jited BPF program.

Pull parallel filesystem directory handling update from Al Viro.

This is the main parallel directory work by Al that makes the vfs layer
able to do lookup and readdir in parallel within a single directory.
That's a big change, since this used to be all protected by the
directory inode mutex.

The inode mutex is replaced by an rwsem, and serialization of lookups of
a single name is done by a "in-progress" dentry marker.

The series begins with xattr cleanups, and then ends with switching
filesystems over to actually doing the readdir in parallel (switching to
the "iterate_shared()" that only takes the read lock).

A more detailed explanation of the process from Al Viro:
 "The xattr work starts with some acl fixes, then switches ->getxattr to
  passing inode and dentry separately.  This is the point where the
  things start to get tricky - that got merged into the very beginning
  of the -rc3-based #work.lookups, to allow untangling the
  security_d_instantiate() mess.  The xattr work itself proceeds to
  switch a lot of filesystems to generic_...xattr(); no complications
  there.

  After that initial xattr work, the series then does the following:

   - untangle security_d_instantiate()

   - convert a bunch of open-coded lookup_one_len_unlocked() to calls of
     that thing; one such place (in overlayfs) actually yields a trivial
     conflict with overlayfs fixes later in the cycle - overlayfs ended
     up switching to a variant of lookup_one_len_unlocked() sans the
     permission checks.  I would've dropped that commit (it gets
     overridden on merge from #ovl-fixes in #for-next; proper resolution
     is to use the variant in mainline fs/overlayfs/super.c), but I
     didn't want to rebase the damn thing - it was fairly late in the
     cycle...

   - some filesystems had managed to depend on lookup/lookup exclusion
     for *fs-internal* data structures in a way that would break if we
     relaxed the VFS exclusion.  Fixing hadn't been hard, fortunately.

   - core of that series - parallel lookup machinery, replacing
     ->i_mutex with rwsem, making lookup_slow() take it only shared.  At
     that point lookups happen in parallel; lookups on the same name
     wait for the in-progress one to be done with that dentry.

     Surprisingly little code, at that - almost all of it is in
     fs/dcache.c, with fs/namei.c changes limited to lookup_slow() -
     making it use the new primitive and actually switching to locking
     shared.

   - parallel readdir stuff - first of all, we provide the exclusion on
     per-struct file basis, same as we do for read() vs lseek() for
     regular files.  That takes care of most of the needed exclusion in
     readdir/readdir; however, these guys are trickier than lookups, so
     I went for switching them one-by-one.  To do that, a new method
     '->iterate_shared()' is added and filesystems are switched to it
     as they are either confirmed to be OK with shared lock on directory
     or fixed to be OK with that.  I hope to kill the original method
     come next cycle (almost all in-tree filesystems are switched
     already), but it's still not quite finished.

   - several filesystems get switched to parallel readdir.  The
     interesting part here is dealing with dcache preseeding by readdir;
     that needs minor adjustment to be safe with directory locked only
     shared.

     Most of the filesystems doing that got switched to in those
     commits.  Important exception: NFS.  Turns out that NFS folks, with
     their, er, insistence on VFS getting the fuck out of the way of the
     Smart Filesystem Code That Knows How And What To Lock(tm) have
     grown the locking of their own.  They had their own homegrown
     rwsem, with lookup/readdir/atomic_open being *writers* (sillyunlink
     is the reader there).  Of course, with VFS getting the fuck out of
     the way, as requested, the actual smarts of the smart filesystem
     code etc. had become exposed...

   - do_last/lookup_open/atomic_open cleanups.  As the result, open()
     without O_CREAT locks the directory only shared.  Including the
     ->atomic_open() case.  Backmerge from #for-linus in the middle of
     that - atomic_open() fix got brought in.

   - then comes NFS switch to saner (VFS-based ;-) locking, killing the
     homegrown "lookup and readdir are writers" kinda-sorta rwsem.  All
     exclusion for sillyunlink/lookup is done by the parallel lookups
     mechanism.  Exclusion between sillyunlink and rmdir is a real rwsem
     now - rmdir being the writer.

     Result: NFS lookups/readdirs/O_CREAT-less opens happen in parallel
     now.

   - the rest of the series consists of switching a lot of filesystems
     to parallel readdir; in a lot of cases ->llseek() gets simplified
     as well.  One backmerge in there (again, #for-linus - rockridge
     fix)"

Pull power management updates from Rafael Wysocki:
 "The majority of changes go into the cpufreq subsystem this time.

  To me, quite obviously, the biggest ticket item is the new "schedutil"
  governor.  Interestingly enough, it's the first new cpufreq governor
  since the beginning of the git era (except for some out-of-the-tree
  ones).

  There are two main differences between it and the existing governors.
  First, it uses the information provided by the scheduler directly for
  making its decisions, so it doesn't have to track anything by itself.
  Second, it can invoke drivers (supporting that feature) to adjust CPU
  performance right away without having to spawn work items to be
  executed in process context or similar.  Currently, the acpi-cpufreq
  driver is the only one supporting that mode of operation, but then it
  is used on a large number of systems.

  The "schedutil" governor as included here is very simple and mostly
  regarded as a foundation for future work on the integration of the
  scheduler with CPU power management (in fact, there is work in
  progress on top of it already).  Nevertheless it works and the
  preliminary results obtained with it are encouraging.

  There also is some consolidation of CPU frequency management for ARM
  platforms that can add their machine IDs the the new stub dt-platdev
  driver now and that will take care of creating the requisite platform
  device for cpufreq-dt, so it is not necessary to do that in platform
  code any more.  Several ARM platforms are switched over to using this
  generic mechanism.

  In addition to that, the intel_pstate driver is now going to respect
  CPU frequency limits set by the platform firmware (or a BMC) and
  provided via the ACPI _PPC object.

  The devfreq subsystem is getting a new "passive" governor for SoCs
  subsystems that will depend on somebody else to manage their voltage
  rails and its support for Samsung Exynos SoCs is consolidated.

  The rest is support for new hardware (Intel Broxton support in
  intel_idle for one example), bug fixes, optimizations and cleanups in
  a number of places.

  Specifics:

   - New cpufreq "schedutil" governor (making decisions based on CPU
     utilization information provided by the scheduler and capable of
     switching CPU frequencies right away if the underlying driver
     supports that) and support for fast frequency switching in the
     acpi-cpufreq driver (Rafael Wysocki)

d93a47f735 bpf, s390: add support for constant blinding 
This patch adds recently added constant blinding helpers into the
s390 eBPF JIT. In the bpf_int_jit_compile() path, requirements are
to utilize bpf_jit_blind_constants()/bpf_jit_prog_release_other()
pair for rewriting the program into a blinded one, and to map the
BPF_REG_AX register to a CPU register. The mapping of BPF_REG_AX
is at r12 and similarly like in x86 case performs reloading when
ld_abs/ind is used. When blinding is not used, there's no additional
overhead in the generated image.

When BPF_REG_AX is used, we don't need to emit skb->data reload when
helper function changed skb->data, as this will be reloaded later
on anyway from stack on ld_abs/ind, where skb->data is needed. s390
allows for this w/o much additional complexity unlike f.e. x86.

to utilize bpf_jit_blind_constants()/bpf_jit_prog_release_other()
pair for rewriting the program into a blinded one, and to map the

When blinding is not used, there's zero additional overhead in the
