9efeccacd3 linux: drop __bitwise__ everywhere 
__bitwise__ used to mean "yes, please enable sparse checks
unconditionally", but now that we dropped __CHECK_ENDIAN__
__bitwise is exactly the same.
There aren't many users, replace it by __bitwise everywhere.

a57cb1c1d7 Merge branch 'akpm' (patches from Andrew) 
Merge more updates from Andrew Morton:

 - a few misc things

 - kexec updates

 - DMA-mapping updates to better support networking DMA operations

 - IPC updates

 - various MM changes to improve DAX fault handling

 - lots of radix-tree changes, mainly to the test suite. All leading up
   to reimplementing the IDA/IDR code to be a wrapper layer over the
   radix-tree. However the final trigger-pulling patch is held off for
   4.11.

* emailed patches from Andrew Morton <akpm@linux-foundation.org>: (114 commits)
  radix tree test suite: delete unused rcupdate.c
  radix tree test suite: add new tag check
  radix-tree: ensure counts are initialised
  radix tree test suite: cache recently freed objects
  radix tree test suite: add some more functionality
  idr: reduce the number of bits per level from 8 to 6
  rxrpc: abstract away knowledge of IDR internals
  tpm: use idr_find(), not idr_find_slowpath()
  idr: add ida_is_empty
  radix tree test suite: check multiorder iteration
  radix-tree: fix replacement for multiorder entries
  radix-tree: add radix_tree_split_preload()
  radix-tree: add radix_tree_split
  radix-tree: add radix_tree_join

1a29d85eb0 mm: use vmf->address instead of of vmf->virtual_address 
Every single user of vmf->virtual_address typed that entry to unsigned
long before doing anything with it so the type of virtual_address does
not really provide us any additional safety.  Just use masked
vmf->address which already has the appropriate type.

7a5c8b57ce sparc: implement watchdog_nmi_enable and watchdog_nmi_disable 
Implement functions watchdog_nmi_enable and watchdog_nmi_disable to
enable/disable nmi watchdog.  Sparc uses arch specific nmi watchdog
handler.  Currently, we do not have a way to enable/disable nmi watchdog
dynamically.  With these patches we can enable or disable arch specific
nmi watchdogs using proc or sysctl interface.

Example commands.
To enable: echo 1 >  /proc/sys/kernel/nmi_watchdog
To disable: echo 0 >  /proc/sys/kernel/nmi_watchdog

It can also achieved using the sysctl parameter kernel.nmi_watchdog

8a3385d2d4 arch/arc: add option to skip sync on DMA mapping 
Patch series "Add support for DMA writable pages being writable by the
network stack", v3.

The first 19 patches in the set add support for the DMA attribute
DMA_ATTR_SKIP_CPU_SYNC on multiple platforms/architectures.  This is
needed so that we can flag the calls to dma_map/unmap_page so that we do
not invalidate cache lines that do not currently belong to the device.
Instead we have to take care of this in the driver via a call to
sync_single_range_for_cpu prior to freeing the Rx page.

Patch 20 adds support for dma_map_page_attrs and dma_unmap_page_attrs so
that we can unmap and map a page using the DMA_ATTR_SKIP_CPU_SYNC
attribute.

Patch 21 adds support for freeing a page that has multiple references
being held by a single caller.  This way we can free page fragments that
were allocated by a given driver.

The last 2 patches use these updates in the igb driver, and lay the
groundwork to allow for us to reimplement the use of build_skb.

This patch (of 23):

This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to
avoid invoking cache line invalidation if the driver will just handle it
later via a sync_for_cpu or sync_for_device call.

401721ecd1 kexec: export the value of phys_base instead of symbol address 
Currently in x86_64, the symbol address of phys_base is exported to
vmcoreinfo.  Dave Anderson complained this is really useless for his
Crash implementation.  Because in user-space utility Crash and
Makedumpfile which exported vmcore information is mainly used for, value
of phys_base is needed to covert virtual address of exported kernel
symbol to physical address.  Especially init_level4_pgt, if we want to
access and go over the page table to look up a PA corresponding to VA,
firstly we need calculate

  page_dir = SYMBOL(init_level4_pgt) - __START_KERNEL_map + phys_base;

Now in Crash and Makedumpfile, we have to analyze the vmcore elf program
header to get value of phys_base.  As Dave said, it would be preferable
if it were readily availabl in vmcoreinfo rather than depending upon the
PT_LOAD semantics.

Hence in this patch change to export the value of phys_base instead of
its virtual address.

And people also complained that KERNEL_IMAGE_SIZE exporting is x86_64
only, should be moved into arch dependent function
arch_crash_save_vmcoreinfo.  Do the moving in this patch.

69f5838479 Revert "kdump, vmcoreinfo: report memory sections virtual addresses" 
This reverts commit 0549a3c02e ("kdump, vmcoreinfo: report memory
sections virtual addresses").

Commit 0549a3c02e tells the userspace utility makedumpfile the
randomized base address of these memmory sections when mm kaslr is
enabled.  However the following patch "kexec: export the value of
phys_base instead of symbol address" makes makedumpfile not need these
addresses any more.

Besides we should use VMCOREINFO_NUMBER to export the value of the
variable so that we can use the existing number_table mechanism of
Makedumpfile to fetch it.  So revert it now.  If needed we can add it
later.

Pull namespace updates from Eric Biederman:
 "After a lot of discussion and work we have finally reachanged a basic
  understanding of what is necessary to make unprivileged mounts safe in
  the presence of EVM and IMA xattrs which the last commit in this
  series reflects. While technically it is a revert the comments it adds
  are important for people not getting confused in the future. Clearing
  up that confusion allows us to seriously work on unprivileged mounts
  of fuse in the next development cycle.

  The rest of the fixes in this set are in the intersection of user
  namespaces, ptrace, and exec. I started with the first fix which
  started a feedback cycle of finding additional issues during review
  and fixing them. Culiminating in a fix for a bug that has been present
  since at least Linux v1.0.

  Potentially these fixes were candidates for being merged during the rc
  cycle, and are certainly backport candidates but enough little things
  turned up during review and testing that I decided they should be
  handled as part of the normal development process just to be certain
  there were not any great surprises when it came time to backport some
  of these fixes"

846221cfb8 Remove references to dead make variable LINUX_INCLUDE 
Commit 4fd06960f1 ("Use the new x86 setup code for i386") introduced a
reference to the make variable LINUX_INCLUDE. That reference got moved
around a bit and copied twice and now there are three references to it.

There has never been a definition of that variable. (Presumably that is
because it started out as a mistyped reference to LINUXINCLUDE.) So this
reference has always been an empty string. Let's remove it before it
spreads any further.

098c30557a Driver core patches for 4.10-rc1 
Here's the new driver core patches for 4.10-rc1.
 
 Big thing here is the nice addition of "functional dependencies" to the
 driver core.  The idea has been talked about for a very long time, great
 job to Rafael for stepping up and implementing it. It's been tested for
 longer than the 4.9-rc1 date, we held off on merging it earlier in order
 to feel more comfortable about it.
 
 Other than that, it's just a handful of small other patches, some good
 cleanups to the mess that is the firmware class code, and we have a test
 driver for the deferred probe logic.
 
 All of these have been in linux-next for a while with no reported
 issues.

36869cb93d Merge branch 'for-4.10/block' of git://git.kernel.dk/linux-block 
Pull block layer updates from Jens Axboe:
 "This is the main block pull request this series. Contrary to previous
  release, I've kept the core and driver changes in the same branch. We
  always ended up having dependencies between the two for obvious
  reasons, so makes more sense to keep them together. That said, I'll
  probably try and keep more topical branches going forward, especially
  for cycles that end up being as busy as this one.

  The major parts of this pull request is:

   - Improved support for O_DIRECT on block devices, with a small
     private implementation instead of using the pig that is
     fs/direct-io.c. From Christoph.

   - Request completion tracking in a scalable fashion. This is utilized
     by two components in this pull, the new hybrid polling and the
     writeback queue throttling code.

   - Improved support for polling with O_DIRECT, adding a hybrid mode
     that combines pure polling with an initial sleep. From me.

   - Support for automatic throttling of writeback queues on the block
     side. This uses feedback from the device completion latencies to
     scale the queue on the block side up or down. From me.

   - Support from SMR drives in the block layer and for SD. From Hannes
     and Shaun.

   - Multi-connection support for nbd. From Josef.

   - Cleanup of request and bio flags, so we have a clear split between
     which are bio (or rq) private, and which ones are shared. From
     Christoph.

   - A set of patches from Bart, that improve how we handle queue
     stopping and starting in blk-mq.

   - Support for WRITE_ZEROES from Chaitanya.

   - Lightnvm updates from Javier/Matias.

   - Supoort for FC for the nvme-over-fabrics code. From James Smart.

   - A bunch of fixes from a whole slew of people, too many to name
     here"

b8d2798f32 This is a fairly quiet release. We don't have any patches to the core 
framework. The only patch that can even be considered "core" adds another
 clk_get() variant. The rest of the changes are in drivers for various SoCs, and
 we have a few bits for ARM shmobile architecture code (dts and mach) due to the
 dependency we're breaking between shmobile architecture code and its clk
 driver. Those shmobile bits have also been pulled into arm-soc tree. Here's the
 summary:
 
 Core:
 
  - Support for devm_get_clk_from_child() used with DT bindings that have
    subnodes with the 'clocks' property
 
 New Drivers:
 
  - Allwinner A64 (sun50i)

edc57ea92c remoteproc updates for v4.10 
Introduces remoteproc "subdevice" support, which allows remoteproc
 driver to associate devices to the "running" state of the remoteproc,
 allowing devices to be probed and removed as the remote processor is
 booted, shut down or recovering from a crash.
 
 Handling of virtio device resources was improved, vring memory is now
 allocated as part of other memory allocation. This ensures that all
 vrings for all virtio devices are allocated before we boot the remote
 processor.
 
 The debugfs mechanism for starting and stopping remoteproc instances was
 replaced with a sysfs interface, also providing a mechanism for
 specifying firmware to use by the instance. This allows user space to
 load and boot use case specific firmware on remote processors.
 
 New drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as
 removal of the unused StE modem loader.
 
 Finally support for crash recovery in the Qualcomm Wirelss subsystem
 (used for WiFi/BT/FM on a number of platforms) and a number of bug fixes
 and cleanups.

5233c331cf It's been an busy period for mmc. Quite some changes in the mmc core, two new 
mmc host drivers, some existing drivers being extended to support new IP
 versions and lots of other updates.
 
 MMC core:
  - Delete eMMC packed command support
  - Introduce mmc_abort_tuning() to enable eMMC tuning to fail gracefully
  - Introduce mmc_can_retune() to see if a host can be retuned
  - Re-work and improve the sequence when sending a CMD6 for mmc
  - Enable CDM13 polling when switching to HS and HS DDR mode for mmc
  - Relax checking for CMD6 errors after switch to HS200
  - Re-factoring the code dealing with the mmc block queue
  - Recognize whether the eMMC card supports CMDQ
  - Fix 4K native sector check
  - Don't power off the card when starting the host
  - Increase MMC_IOC_MAX_BYTES to support bigger firmware binaries
  - Improve error handling and drop meaningless BUG_ONs()
  - Lots of clean-ups and changes to improve the quality of the code
 
 MMC host:
  - sdhci: Fix tuning sequence and clean-up the related code
  - sdhci: Add support to via DT override broken SDHCI cap register bits
  - sdhci-cadence: Add new driver for Cadence SD4HC SDHCI variant
  - sdhci-msm: Update clock management
  - sdhci-msm: Add support for eMMC HS400 mode
  - sdhci-msm: Deploy runtime/system PM support
  - sdhci-iproc: Extend driver support to newer IP versions
  - sdhci-pci: Add support for Intel GLK
  - sdhci-pci: Add support for Intel NI byt sdio
  - sdhci-acpi: Add support for 80860F14 UID 2 SDIO bus
  - sdhci: Lots of various small improvements and clean-ups
  - tmio: Add support for tuning
  - sh_mobile_sdhi: Add support for tuning
  - sh_mobile_sdhi: Extend driver to support SDHI IP on R7S72100 SoC
  - sh_mobile_sdhi: remove support for sh7372
  - davinci: Use mmc_of_parse() to enable generic mmc DT bindings
  - meson: Add new driver to support GX platforms
  - dw_mmc: Deploy generic runtime/system PM support
  - dw_mmc: Lots of various small improvements
 
 As a part of the mmc changes this time, I have also pulled in an immutable
 branch/tag (soc-device-match-tag1) hosted by Geert Uytterhoeven, to share the
 implementation of the new soc_device_match() interface. This is needed by the
 below mmc related changes:
  - mmc: sdhci-of-esdhc: Get correct IP version for T4240-R1.0-R2.0
  - soc: fsl: add GUTS driver for QorIQ platforms

061ad5038c Bulk GPIO changes for the v4.10 kernel cycle: 
Core changes:
 
 - Simplify threaded interrupt handling: instead of passing
   numbed parameters to gpiochip_irqchip_add_chained() we
   create a new call: gpiochip_irqchip_add_nested() so the two
   types are clearly semantically different. Also make sure
   that all nested chips call gpiochip_set_nested_irqchip()
   which is necessary for IRQ resend to work properly if
   it happens.
 
 - Return error on seek operations for the chardev.
 
 - Clamp values set as part of gpio[d]_direction_output() so
   that anything != 0 will be send down to the driver as "1"
   not the value passed in.
 
 - ACPI can now support naming of GPIO lines, hogs and holes
   in the GPIO lists.
 
 New drivers:
 
 - The SX150x driver was deemed unfit for the GPIO subsystem
   and was moved over to a combined GPIO+pinctrl driver in the
   pinctrl subsystem.
 
 New features:
 
 - Various cleanups to various drivers.
