drivers/hwspinlock: use correct radix tree API
radix_tree_is_indirect_ptr() is an internal API. The correct call to
use is radix_tree_deref_retry() which has the appropriate unlikely()
annotation.

zram: introduce per-device debug_stat sysfs node
debug_stat sysfs is read-only and represents various debugging data that zram developers may need. This file is not meant to be used by anyone else: its content is not documented and will change any time w/o any notice. Therefore, the output of debug_stat file contains a version string. To avoid any confusion, we will increase the version number every time we modify the output. At the moment this file exports only one value -- the number of re-compressions, IOW, the number of times compression fast path has failed. This stat is temporary any will be useful in case if any per-cpu compression streams regressions will be reported.

zram: remove max_comp_streams internals
Remove the internal part of max_comp_streams interface, since we switched to per-cpu streams. We will keep RW max_comp_streams attr around, because: a) we may (silently) switch back to idle compression streams list and don't want to disturb user space b) max_comp_streams attr must wait for the next 'lay off cycle'; we give user space 2 years to adjust before we remove/downgrade the attr, and there are already several attrs scheduled for removal in 4.11, so it's too late for max_comp_streams. This slightly change a user visible behaviour: - First, reading from max_comp_stream file now will always return the number of online CPUs. - Second, writing to max_comp_stream will not take any effect.

zram: user per-cpu compression streams
Remove idle streams list and keep compression streams in per-cpu data.
This removes two contented spin_lock()/spin_unlock() calls from write
path and also prevent write OP from being preempted while holding the
compression stream, which can cause slow downs.
For instance, let's assume that we have N cpus and N-2
max_comp_streams.TASK1 owns the last idle stream, TASK2-TASK3 come in
with the write requests:
TASK1 TASK2 TASK3
zram_bvec_write()
spin_lock
find stream
spin_unlock
compress
<<preempted>> zram_bvec_write()
spin_lock
find stream
spin_unlock
no_stream
schedule
zram_bvec_write()
spin_lock
find_stream
spin_unlock
no_stream
schedule
spin_lock
release stream
spin_unlock
wake up TASK2
not only TASK2 and TASK3 will not get the stream, TASK1 will be
preempted in the middle of its operation; while we would prefer it to
finish compression and release the stream.
Test environment: x86_64, 4 CPU box, 3G zram, lzo
The following fio tests were executed:
read, randread, write, randwrite, rw, randrw
with the increasing number of jobs from 1 to 10.

zsmalloc: require GFP in zs_malloc()
Pass GFP flags to zs_malloc() instead of using a fixed mask supplied to zs_create_pool(), so we can be more flexible, but, more importantly, we need this to switch zram to per-cpu compression streams -- zram will try to allocate handle with preemption disabled in a fast path and switch to a slow path (using different gfp mask) if the fast one has failed. Apart from that, this also align zs_malloc() interface with zspool/zbud.

irqchip: nps: add 64BIT dependency
The newly added nps irqchip driver causes build warnings on ARM64. include/soc/nps/common.h: In function 'nps_host_reg_non_cl': include/soc/nps/common.h:148:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] As the driver is only used on ARC, we don't need to see it without COMPILE_TEST elsewhere, and we can avoid the warnings by only building on 32-bit architectures even with CONFIG_COMPILE_TEST.

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.

Merge branch 'i2c/for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
- Peter Rosin did some major rework on the locking of i2c muxes by
seperating parent-locked muxes and mux-locked muxes.
This avoids deadlocks/workarounds when the mux itself needs i2c
commands for muxing. And as a side-effect, other workarounds in the
media layer could be eliminated. Also, Peter stepped up as the i2c
mux maintainer and will keep an eye on these changes.
- major updates to the octeon driver
- add a helper to the core to generate the address+rw_bit octal and
make drivers use it
- quite a bunch of driver updates

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

Pull iscsi_ibft updates from Konrad Rzeszutek Wilk:
"The pull has two features - both of them expand the SysFS entries:
- 'prefix-len' - which is subnet_mask_prefix of the iBFT header.
- 'acpi_header' dir with: 'iBFT', OEM-ID (whatever it extracts from
the iBFT header) and OEM_TABLE_ID (also whatever it extracts from
the iBFT header). This is to help NIC drivers to figure out during
bootup how to deal with BIOS created iBFT tables (like by TianoCore
UEFI implemenation)"

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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVzuXkGCrR//JCVInAQKb5BAAv2HuJ/tDjC8nNfYi0/aIt4uaRfRWE84t +nIpdKl/pB9AQo+HdG9WNihHs2GN44PdQRrDZ1enQX8nvTzc+dUl0AI1GZmUDpF/ zCV2UJ39HMZcEPwf8lZk9X/JP4VOkJDM5pDgNZnnqdvkq0oqtKzmh0Kt6m2g6fIS LR3FVtCRxJDeT+pT+EpoN4jpW0cb3mjTWbn/a8Ar3BH07KBA3U22MVJhHArLjS30 /aXP+AkgdvlgmBher5z44N6Qd/KOLn78rnE4LCRC4FwSCqA+qqPJQNGNblV5MHjE s5CYTqlihqLiGapqJ4zGBhmqj0XU/3kFVboGqYlTGjzMkOFgjddTpMdfkBUoG5oJ UubJ51zzSLXTcMwILGNXVls4YjJRKwNH7jeSjuMqpWrAYP4qBcMn/HQ1GqUjkNv+ yWkheHiLDYgYkIDOBDuFUtJ7OXiVumGGxIE+r2K/sXeNI7gFcDxFExMIo11vPAWP WJ8ydTchyb/RUQbzhjEXhoIeCZwXQfe9s11qsyFQDCZLleWYQGs3gFKdEI1E7+BE oe018BSP+uaVXdaV18Ne4smwzydLAU9/ieUoO45PAUSN2reV4lWhFTlNiiiMd3Id IWoYwpxqP2VW9zJvLz6QGF/P+3cZ00m/1lecJCKHHPBmbUijCHWJmgLT73AdSXmR YIJ2UM5QMiY= =x+iD -----END PGP SIGNATURE----- Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, these contain various things that touch the drivers/ directory but got merged through arm-soc for practical reasons.

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:

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.

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.

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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVzuXUWCrR//JCVInAQKLTw/7BjSDJGRMsioOJ33Bg3LP92rJHPrVttWc vG8ULnc2QgcFTofDqgyPza2p2XuV868I7jEw4d/qDXOkeIw3ddLKjdCMzHq5r1CO G9W+ZlIw54na/Lh/CMVdMN1M3+64K4Fmp1IiBG66OhhFY8Zg3xterSEBk8V1+00K LNdiq6aJ1yROyHQtYbe+CtqTi/pJ9AmkBoRk4MnfgIMQyywESLlYDRkc3VXWEFXv 3MBszgujEIE1R+XozC2VMDPrirdwjJv71x/tlE0nveOcAIam57B/6e5yLnVCQHpu UCK8x39cj/PwWlwoBExKXNMwbTKCy03AhXjkxDmJ3bD+7FK1sEtFzcyBiwOjiZQq CBttcwqGbtrGIsLbrbpEh9hAWbWNaparbChWW7RBC1sBIG11zd0HVYjzsKppmXsZ 3LUl4KbkGw+grKa+AnsM+e9vGu+J+2vIh9sDVvs0dbXCZp5ILgExbnurxMwbg/J1 QVycR8cjS2vs+79tTfakgVCSADvpdNbMcnYLz9GM5IS9j8bOlOhv1OhKtMFOue6y zCIZyffDJqhU0M3xk78JQSx3Rt4FacDjYJdlqN27AQ125QT2kYmfGR2x/en52ARS 9QwauVp+5WcaoySdWi4TCpOMHV7FP40zhJ3G7TXZARaBccN0kCTfdF/QstLhAa0L u+TVN4A1cBw= =au7y -----END PGP SIGNATURE----- Merge tag 'armsoc-cleanups-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups and fixes from Arnd Bergmann: "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.

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.

- based on Jens' 'for-4.7/core' to have DM thinp's discard support use
bio_inc_remaining() and the block core's new async __blkdev_issue_discard() interface - make DM multipath's fast code-paths lockless, using lockless_deference, to significantly improve large NUMA performance when using blk-mq.

Merge branch 'for-4.7/drivers' of git://git.kernel.dk/linux-block
Pull block driver updates from Jens Axboe:
"On top of the core pull request, this is the drivers pull request for
this merge window. This contains:
- Switch drivers to the new write back cache API, and kill off the
flush flags. From me.
- Kill the discard support for the STEC pci-e flash driver. It's
trivially broken, and apparently unmaintained, so it's safer to
just remove it. From Jeff Moyer.
- A set of lightnvm updates from the usual suspects (Matias/Javier,
and Simon), and fixes from Arnd, Jeff Mahoney, Sagi, and Wenwei
Tao.
- A set of updates for NVMe:
- Turn the controller state management into a proper state
machine. From Christoph.
- Shuffling of code in preparation for NVMe-over-fabrics, also
from Christoph.
- Cleanup of the command prep part from Ming Lin.
- Rewrite of the discard support from Ming Lin.
- Deadlock fix for namespace removal from Ming Lin.
- Use the now exported blk-mq tag helper for IO termination.
From Sagi.
- Various little fixes from Christoph, Guilherme, Keith, Ming
Lin, Wang Sheng-Hui.
- Convert mtip32xx to use the now exported blk-mq tag iter function,
from Keith"
