Linus Torvalds 07c455ee22 platform-drivers-x86 for v4.15-1
For this cycle we have quite an update for the Dell SMBIOS driver
 including WMI work to provide an interface for SMBIOS tokens via sysfs
 and WMI support for 2017+ Dell laptop models. SMM dispatcher code is
 split into a separate driver followed by a new WMI dispatcher.
 The latter provides a character device interface to user space.
 
 The pull request contains a merge of immutable branch from Wolfram Sang
 in order to apply a dependent fix to the Intel CherryTrail Battery
 Management driver.
 
 Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0
 support is added for Intel Skylake.
 
 Peaq WMI hotkeys driver gets its own maintainer and white list of

Linus Torvalds fc35c1966e We have two changes to the core framework this time around. The first being a
large change that introduces runtime PM support to the clk framework. Now we
 properly call runtime PM operations on the device providing a clk when the clk
 is in use. This helps on SoCs where the clks provided by a device need
 something to be powered on before using the clks, like power domains or
 regulators. It also helps power those things down when clks aren't in use. The
 other core change is a devm API addition for clk providers so we can get rid of
 a bunch of clk driver remove functions that are just doing
 of_clk_del_provider().
 
 Outside of the core, we have the usual addition of clk drivers and smattering
 of non-critical fixes to existing drivers. The biggest diff is support for
 Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch
 of data.
 
 By the way, we're trying something new here where we build the tree up with
 topic branches. We plan to work this into our workflow so that we don't step
 on each other's toes, and so the fixes branch can be merged on an as-needed
 basis.
 
 Core:
  - Runtime PM support for clk providers
  - devm API for of_clk_add_hw_provider()
 
 New Drivers:
  - Mediatek MT2712 and MT7622
  - Renesas R-Car V3M SoC
 
 Updates:
  - Runtime PM support for Samsung exynos5433/exynos4412 providers
  - Removal of clkdev aliases on Samsung SoCs
  - Convert clk-gpio to use gpio descriptors
  - Various driver cleanups to match kernel coding style

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "We have two changes to the core framework this time around.

  The first being a large change that introduces runtime PM support to
  the clk framework. Now we properly call runtime PM operations on the
  device providing a clk when the clk is in use. This helps on SoCs
  where the clks provided by a device need something to be powered on
  before using the clks, like power domains or regulators. It also helps
  power those things down when clks aren't in use.

  The other core change is a devm API addition for clk providers so we
  can get rid of a bunch of clk driver remove functions that are just
  doing of_clk_del_provider().

  Outside of the core, we have the usual addition of clk drivers and
  smattering of non-critical fixes to existing drivers. The biggest diff
  is support for Mediatek MT2712 and MT7622 SoCs, but those patches
  really just add a bunch of data.

  By the way, we're trying something new here where we build the tree up
  with topic branches. We plan to work this into our workflow so that we
  don't step on each other's toes, and so the fixes branch can be merged
  on an as-needed basis.

  Summary:

  Core:
   - runtime PM support for clk providers
   - devm API for of_clk_add_hw_provider()

  New Drivers:
   - Mediatek MT2712 and MT7622
   - Renesas R-Car V3M SoC

  Updates:
   - runtime PM support for Samsung exynos5433/exynos4412 providers
   - removal of clkdev aliases on Samsung SoCs
   - convert clk-gpio to use gpio descriptors
   - various driver cleanups to match kernel coding style
   - Amlogic Video Processing Unit VPU and VAPB clks
   - sigma-delta modulation for Allwinner audio PLLs
   - Allwinner A83t Display clks
   - support for the second display unit clock on Renesas RZ/G1E
   - suspend/resume support for Renesas R-Car Gen3 CPG/MSSR
   - new clock ids for Rockchip rk3188 and rk3368 SoCs
   - various 'const' markings on clk_ops structures
   - RPM clk support on Qualcomm MSM8996/MSM8660 SoCs"

Linus Torvalds a3841f94c7 libnvdimm for 4.15
* Introduce MAP_SYNC and MAP_SHARED_VALIDATE, a mechanism to enable
  'userspace flush' of persistent memory updates via filesystem-dax
   mappings. It arranges for any filesystem metadata updates that may be
   required to satisfy a write fault to also be flushed ("on disk") before
   the kernel returns to userspace from the fault handler. Effectively
   every write-fault that dirties metadata completes an fsync() before
   returning from the fault handler. The new MAP_SHARED_VALIDATE mapping
   type guarantees that the MAP_SYNC flag is validated as supported by the
   filesystem's ->mmap() file operation.
 
 * Add support for the standard ACPI 6.2 label access methods that
   replace the NVDIMM_FAMILY_INTEL (vendor specific) label methods. This
   enables interoperability with environments that only implement the
   standardized methods.
 
 * Add support for the ACPI 6.2 NVDIMM media error injection methods.
 
 * Add support for the NVDIMM_FAMILY_INTEL v1.6 DIMM commands for latch
   last shutdown status, firmware update, SMART error injection, and
   SMART alarm threshold control.
 
 * Cleanup physical address information disclosures to be root-only.
 
 * Fix revalidation of the DIMM "locked label area" status to support
   dynamic unlock of the label area.
 
 * Expand unit test infrastructure to mock the ACPI 6.2 Translate SPA
   (system-physical-address) command and error injection commands.

Linus Torvalds 527d147074 ARM: Device-tree updates for 4.15
We add device tree files for a couple of additional SoCs in various areas:
 
 Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for networking,
 Amlogic A113D for audio, and Renesas R-Car V3M for automotive.
 
 As usual, lots of new boards get added based on those and other SoCs:
 
  - Actions S500 based CubieBoard6 single-board computer
 
  - Amlogic Meson-AXG A113D based development board
  - Amlogic S912 based Khadas VIM2 single-board computer
  - Amlogic S912 based Tronsmart Vega S96 set-top-box
 
  - Allwinner H5 based NanoPi NEO Plus2 single-board computer
  - Allwinner R40 based Banana Pi M2 Ultra and Berry single-board computers
  - Allwinner A83T based TBS A711 Tablet
 
  - Broadcom Hurricane 2 based Ubiquiti UniFi Switch 8
  - Broadcom bcm47xx based Luxul XAP-1440/XAP-810/ABR-4500/XBR-4500
      wireless access points and routers
 
  - NXP i.MX51 based Zodiac Inflight Innovations RDU1 board
  - NXP i.MX53 based GE Healthcare PPD biometric monitor
  - NXP i.MX6 based Pistachio single-board computer
  - NXP i.MX6 based Vining-2000 automotive diagnostic interface
  - NXP i.MX6 based Ka-Ro TX6 Computer-on-Module in additional variants
 
  - Qualcomm MSM8974 (Snapdragon 800) based Fairphone 2 phone
  - Qualcomm MSM8974pro (Snapdragon 801) based Sony Xperia Z2 Tablet

 For existing SoC support, there was a lot of ongoing work, as usual
 most of that concentrated on the Renesas, Rockchip, OMAP, i.MX, Amlogic

 Rob Herring and many others worked on reducing the number of issues that
 the latest version of 'dtc' now warns about. Unfortunately there is still
 a lot left to do.
 
 A rework of the ARM foundation model introduced several new files
 for common variations of the model.

Linus Torvalds 8c60969856 ARM: SoC platform updates for 4.15
Most of the commits are for defconfig changes, to enable newly added
 drivers or features that people have started using. For the changed
 lines lines, we have mostly cleanups, the affected platforms are
 OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
 
 The largest single change is the introduction of the TI "sysc" bus
 driver, with the intention of cleaning up more legacy code.
 
 Two new SoC platforms get added this time:
 - Allwinner R40 is a modernized version of the A20 chip, now
   with a Quad-Core ARM Cortex-A7. According to the manufacturer,
   it is intended for "Smart Hardware"
 - Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family
   of chips meant for managed gigabit ethernet switches, based
   around a Cortex-A9 CPU.
 
 Finally, we gain SMP support for two platforms: Renesas R-Car E2
 and Amlogic Meson8/8b, which were previously added but only supported
 uniprocessor operation.

Linus Torvalds b630a23a73 This is the bulk of pin control changes for the v4.15
kernel cycle:
 
 Core:
 
 - The pin control Kconfig entry PINCTRL is now turned into
   a menuconfig option. This obviously has the implication of
   making the subsystem menu visible in menuconfig. This is
   happening because of two things:
 
   - Intel have started to deploy and depend on pin controllers
     in a way that is affecting users directly. This happens
     on the highly integrated laptop chipsets named after
     geographical places: baytrail, broxton, cannonlake,
     cedarfork, cherryview, denverton, geminilake, lewisburg,
     merrifield, sunrisepoint... It started a while back and
     now it is ever more evident that this is crucial
     infrastructure for x86 laptops and not an embedded
     obscurity anymore. Users need to be aware.
 
   - Pin control expanders on I2C and SPI that are
     arch-agnostic. Currently Semtech SX150X and Microchip
     MCP28x08 but more are expected. Users will have to be
     able to configure these in directly for their set-up.
 
 - Just go and select GPIOLIB now that we made sure that
   GPIOLIB is a very vanilla subsystem. Do not depend on
   it, if we need it, select it.
 
 - Exposing the pin control subsystem in menuconfig uncovered
   a bunch of obscure bugs that are now hopefully fixed,
   all more or less pertaining to Blackfin.
 
 - Unified namespace for cross-calls between pin control and
   GPIO.
 
 - New support for clock skew/delay generic DT bindings
   and generic pin config options for this.
 
 - Minor documentation improvements.
 
 Various:
 
 - The Renesas SH-PFC pin controller has evolved a lot. It seems
   Renesas are churning out new SoCs by the minute.
 
 - A bunch of non-critical fixes for the Rockchip driver.
 
 - Improve the use of library functions instead of open coding.
 
 - Support the MCP28018 variant in the MCP28x08 driver.
 
 - Static constifying.

Linus Torvalds 2bf16b7a73 Char/Misc patches for 4.15-rc1
Here is the big set of char/misc and other driver subsystem patches for
 4.15-rc1.
 
 There are small changes all over here, hyperv driver updates, pcmcia
 driver updates, w1 driver updats, vme driver updates, nvmem driver
 updates, and lots of other little one-off driver updates as well.  The
 shortlog has the full details.
 
 Note, there will be a merge conflict in drivers/misc/lkdtm_core.c when
 merging to your tree as one lkdtm patch came in through the perf tree as
 well as this one.  The resolution is to take the const change that this
 tree provides.
 
 All of these have been in linux-next for quite a while with no reported
 issues.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull rdma updates from Doug Ledford:
 "This is a fairly plain pull request. Lots of driver updates across the
  stack, a huge number of static analysis cleanups including a close to
  50 patch series from Bart Van Assche, and a number of new features
  inside the stack such as general CQ moderation support.

  Nothing really stands out, but there might be a few conflicts as you
  take things in. In particular, the cleanups touched some of the same
  lines as the new timer_setup changes.

  Everything in this pull request has been through 0day and at least two
  days of linux-next (since Stephen doesn't necessarily flag new
  errors/warnings until day2). A few more items (about 30 patches) from
  Intel and Mellanox showed up on the list on Tuesday. I've excluded
  those from this pull request, and I'm sure some of them qualify as
  fixes suitable to send any time, but I still have to review them
  fully. If they contain mostly fixes and little or no new development,
  then I will probably send them through by the end of the week just to
  get them out of the way.

  There was a break in my acceptance of patches which coincides with the
  computer problems I had, and then when I got things mostly back under
  control I had a backlog of patches to process, which I did mostly last
  Friday and Monday. So there is a larger number of patches processed in
  that timeframe than I was striving for.

  Summary:
   - Add iWARP support to qedr driver
   - Lots of misc fixes across subsystem
   - Multiple update series to hns roce driver

 "The big highlight is support for the Scalable Vector Extension (SVE)
  which required extensive ABI work to ensure we don't break existing

  new vector context (<= 2 kbit per vector register). There's further
  work to be done optimising things like exception return, but the ABI
  is solid now.

Linus Torvalds b293fca43b RISC-V Port for Linux 4.15 v9
This tag contains the core RISC-V Linux port, which has been through
 nine rounds of review on various mailing lists.  The port is not
 complete: there's some cleanup patches moving through the review
 process, a whole bunch of drivers that need some work, and a lot of
 feature additions that will be needed.
 
 The patches contained in this tag have been through nine rounds of
 review on the various mailing lists.  I have some outstanding cleanup
 patches, but since there's been so much review on these patches I
 thought it would be best to submit them as-is and then submit explicit
 cleanup patches so everyone can review them.  This first patch set is
 big enough that it's a bit of a pain to constantly rewrite, and it's
 caused a few headaches with various contributors.
 
 The port is definately a work in progress.  While what's there builds
 and boots with 4.14, it's a bit hard to actually see anything happen
 because there are no device drivers yet.  I maintain a staging branch
 that contains all the device drivers and cleanup that actually works,
 but those patches won't all be ready for a while.  I'd like to get what
 we currently have into your tree so everyone can start working from a
 single base -- of particular importance is allowing the glibc
 upstreaming process to proceed so we can sort out any possibly lingering
 user-visible ABI problems we might have.
 
 Copied below is the ChangeLog that contains the history of this patch
 set:
 
 (v9) As per suggestions on our v8 patch set, I've split the core architecture code
 out from our drivers and would like to submit this patch set to be included
 into linux-next, with the goal being to be merged in during the next merge
 window.  This patch set is based on 4.14-rc2, but if it's better to have it
 based on something else then I can change it around.
 
 This patch set contains just the core arch code for RISC-V, so while it builds
 an nominally boots, you can't print or take an interrupt so it's not that
 useful.  If you're looking to actually boot a system it would probably be
 better to use the full patch set listed below.
 
 We've collected a handful of tags from reviewers, and the remainder of the
 patch set only got minimal feedback last time.  Here's what changed:
 
  * We now use the device tree to initialize the timer driver so it's less
    tighly coupled with the arch port.
  * I cleaned up the defconfigs -- there's actually now just one, and it's
    empty.  For now I think we're OK with what the kernel sets as defaults, but
    I anticipate we'll begin to expand this as people start to use the port
    more.
  * The VDSO symbols version is sane.
  * We WFI while spinning in the boot loop.
  * A handful of comments have been added.
 
 While there are still a handful of FIXMEs in this patch set, we've started to
 get enough interest from various users and contributors that maintaining an out
 of tree patch set is starting to become a big burden.  Hopefully the patches
 are good enough to merge now, which will at least get everyone working in a
 more reasonable manner as we clean up the remaining issues.
 
 This patch set is also availiable on github
 
   https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9-arch
 
 as is the entire patch set necessary to get a more functional RISC-V system up
 and running, including a handful of patches that aren't ready for upstream yet.
 
   https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9
 
 Hopefully I've managed to get everyone's feedback
 
 Here's the change highlights from the whole patch set:
 
 (v8) I know it may not be the ideal time to submit a patch set right now, as
 it's the middle of the merge window, but things have calmed down quite a bit in
 the last month so I thought it would be good to get everyone on the same page.
 There's been a handful of changes since the last patch set, but most of them
 are fairly minor:
 
 * We changed PAGE_OFFSET to allowing mapping more physical memory on 64-bit
   systems.  This is user configurable, as it triggers a different code model
   that generates slightly less efficient code.
 * The device tree binding documentation is back, I'd managed to lose it at some
   point.
 * We now pass the atomic64 test suite.  The SBI timer driver has been
 * refactored.
 
 (v7) It's been a while since my last patch set, but the changes han been fairly
 minimal:
 
  * The PCI cleanup patches have been dropped, we'll do them as a separate patch
    set later.
  * We've the Kconfig entries from CONFIG_ISA_* to CONFIG_RISCV_ISA_*, to make
    grep easier.
  * There have been a handful of memory model related tweaks in I/O land,
    particularly relating the PCI and the upcoming platform specification.
    There are significant comments in the relevant files.  This is still a WIP,
    but I think we're close to getting as good as we're going to get until we
    end up with some more specifications.
 
 (v6) As it's been only a day since the v5 patch set, the changes are pretty
 minimal:
 
  * The patch set is now based on linux-next/master, which I believe is a better
    base now that we're getting closer to upstream.
  * EARLY_PRINTK is no longer an option.  Since the SBI console is reasonable,
    there's no penalty to enabling it (and thus no benefit to disabling it).
  * The mmap syscalls were refactored a bit.
 
 (v5) Things have really started to calm down, so this is fairly similar to the
 v4 patch set.  The most interesting changes include:
 
  * We've moved back to a single patch set.
 
  * SMP support has been fixed, I was accidentally running on a non-SMP
    configuration.  There were various mistakes all over the tree as a result of
    this.
 
  * The cmpxchg syscalls have been removed, as they were deemed a bad idea.  As
    a result, RISC-V Linux systems mandate the A extension.  The corresponding
    Kconfig entry to enable builds on non-A systems has been removed.
 
  * A few more atomic fixes: mostly fence changes, but those resulted in a
    handful of additional macros that were no longer necessary.
 
  * riscv_early_sie has been removed.
 
 (v4) There have only been a few changes since the v3 patch set:
 
  * The cmpxchg64 syscall is no longer enabled on 32-bit systems.  It's not
    possible to provide this on SMP systems, and it's not necessary as glibc
    knows not to call it.
 
  * We provide a ELF_HWCAP so users can determine the ISA of the machine the
    kernel is running on.
 
  * The multi-line comments are in a better form.
 
  * There were a handful of headers that could be replaced with the asm-generic
    versions, and a few unnecessary definitions.
 
  * We no longer use printk, but instead use pr_*.
 
  * A few Kconfig and defconfig entries have been cleaned up.
 
 (v3) A highlight of the changes since the v2 patch set includes:
 
  * We've split out all our drivers into separate patch sets, which I've already
    sent out to the relevant maintainers.  I haven't included those patches in
    this patch set, but some of them are necessary to build our port.  A git
    tree that contains all our patch sets merged together lives at
    <https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v3>.
 
  * The patch set is now split up differently: rather than being split per
    directory it is split per topic.  Hopefully this will make it easier to
    review the port on the mailing list.  The split is a bit rough, so you
    probably still want to look at the patch set as a whole.
 
  * atomic.h has been completely rewritten and is hopefully now correct.  I've
    attempted to sanitize the various other memory model related code as well,
    and I think it should all be sane now aside from a handful of FIXMEs
    commented in the code.
 
  * We've changed the cmpexchg syscall to always exist and to not be
    multiplexed.  There is also a VDSO entry for compare and exchange, which
    allows kernels with the A extension to execute user code without the A
    extension reasonably fast.
 
  * Our user-visible register state now contains enough space for the Q
    extension for 128-bit floating point, as well as a few words to allow
    extensibility to future ISA extensions like the eventual V extension for
    vectors.
 
  * A handful of driver cleanups, but these have been split into separate patch
    sets now so I won't duplicate them here.
 
 (v2) A highlight of the changes since the v1 patch set includes:
 
   * We've split out our drivers into the right places, which means now there's
     a lot more patches.  I'll be submitting these patches to various subsystem
     maintainers and including them in any future RISC-V patch sets until
     they've been merged.
 
   * The SBI console driver has been completely rewritten to use the HVC helpers
     and is now significantly smaller.
 
   * We've begun to use weaker barriers as opposed to just the big "fence".
     There's still some work to do here, specifically:
     - We need fences in the relaxed MMIO functions.
     - The non-relaxed MMIO functions are missing R/W bits on their fences.
     - Many AMOs need the aq and rl bits set.
 
   * We now have thread_info in task_struct.  As a result, sscratch now contains
     TP instead of SP.  This was necessary because thread_info is no longer on
     the stack.
 
   * A few shared routines have been added that we use instead of creating
     another arch copy.

Merge tag 'riscv-for-linus-4.15-arch-v9-premerge' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux

Pull RISC-V architecture support from Palmer Dabbelt:
 "This contains the core RISC-V Linux port, which has been through nine
  rounds of review on various mailing lists. The port is not complete:
  there's some cleanup patches moving through the review process, a
  whole bunch of drivers that need some work, and a lot of feature
  additions that will be needed.

  The patches contained in this tag have been through nine rounds of
  review on the various mailing lists. I have some outstanding cleanup
  patches, but since there's been so much review on these patches I
  thought it would be best to submit them as-is and then submit explicit
  cleanup patches so everyone can review them. This first patch set is
  big enough that it's a bit of a pain to constantly rewrite, and it's
  caused a few headaches with various contributors.

  The port is definately a work in progress. While what's there builds
  and boots with 4.14, it's a bit hard to actually see anything happen
  because there are no device drivers yet. I maintain a staging branch
  that contains all the device drivers and cleanup that actually works,
  but those patches won't all be ready for a while. I'd like to get what
  we currently have into your tree so everyone can start working from a
  single base -- of particular importance is allowing the glibc
  upstreaming process to proceed so we can sort out any possibly
  lingering user-visible ABI problems we might have.

  Copied below is the ChangeLog that contains the history of this patch
  set:

   (v9) As per suggestions on our v8 patch set, I've split the core
        architecture code out from our drivers and would like to submit
        this patch set to be included into linux-next, with the goal
        being to be merged in during the next merge window. This patch
        set is based on 4.14-rc2, but if it's better to have it based on
        something else then I can change it around.

        This patch set contains just the core arch code for RISC-V, so
        while it builds an nominally boots, you can't print or take an
        interrupt so it's not that useful. If you're looking to actually
        boot a system it would probably be better to use the full patch
        set listed below.

        We've collected a handful of tags from reviewers, and the
        remainder of the patch set only got minimal feedback last time.
        Here's what changed:

         - We now use the device tree to initialize the timer driver so
           it's less tighly coupled with the arch port.

         - I cleaned up the defconfigs -- there's actually now just one,
           and it's empty. For now I think we're OK with what the kernel
           sets as defaults, but I anticipate we'll begin to expand this
           as people start to use the port more.

         - The VDSO symbols version is sane.

         - We WFI while spinning in the boot loop.

         - A handful of comments have been added.

        While there are still a handful of FIXMEs in this patch set,
        we've started to get enough interest from various users and
        contributors that maintaining an out of tree patch set is
        starting to become a big burden. Hopefully the patches are good
        enough to merge now, which will at least get everyone working in
        a more reasonable manner as we clean up the remaining issues.

   (v8) I know it may not be the ideal time to submit a patch set right
        now, as it's the middle of the merge window, but things have
        calmed down quite a bit in the last month so I thought it would
        be good to get everyone on the same page. There's been a handful
        of changes since the last patch set, but most of them are fairly
        minor:

         - We changed PAGE_OFFSET to allowing mapping more physical
           memory on 64-bit systems. This is user configurable, as it
           triggers a different code model that generates slightly less
           efficient code.

         - The device tree binding documentation is back, I'd managed to
           lose it at some point.

         - We now pass the atomic64 test suite

         - The SBI timer driver has been refactored.

   (v7) It's been a while since my last patch set, but the changes han
        been fairly minimal:

         - The PCI cleanup patches have been dropped, we'll do them as a
           separate patch set later.

         - We've the Kconfig entries from CONFIG_ISA_* to
           CONFIG_RISCV_ISA_*, to make grep easier.

         - There have been a handful of memory model related tweaks in
           I/O land, particularly relating the PCI and the upcoming
           platform specification. There are significant comments in the
           relevant files. This is still a WIP, but I think we're close
           to getting as good as we're going to get until we end up with
           some more specifications.

   (v6) As it's been only a day since the v5 patch set, the changes are
        pretty minimal:

         - The patch set is now based on linux-next/master, which I
           believe is a better base now that we're getting closer to
           upstream.

         - EARLY_PRINTK is no longer an option. Since the SBI console is
           reasonable, there's no penalty to enabling it (and thus no
           benefit to disabling it).

         - The mmap syscalls were refactored a bit.

   (v5) Things have really started to calm down, so this is fairly
        similar to the v4 patch set. The most interesting changes
        include:

         - We've moved back to a single patch set.

         - SMP support has been fixed, I was accidentally running on a
           non-SMP configuration. There were various mistakes all over
           the tree as a result of this.

         - The cmpxchg syscalls have been removed, as they were deemed a
           bad idea. As a result, RISC-V Linux systems mandate the A
           extension. The corresponding Kconfig entry to enable builds
           on non-A systems has been removed.

         - A few more atomic fixes: mostly fence changes, but those
           resulted in a handful of additional macros that were no
           longer necessary.

         - riscv_early_sie has been removed.

   (v4) There have only been a few changes since the v3 patch set:

         - The cmpxchg64 syscall is no longer enabled on 32-bit systems.
           It's not possible to provide this on SMP systems, and it's
           not necessary as glibc knows not to call it.

         - We provide a ELF_HWCAP so users can determine the ISA of the
           machine the kernel is running on.

         - The multi-line comments are in a better form.

         - There were a handful of headers that could be replaced with
           the asm-generic versions, and a few unnecessary definitions.

         - We no longer use printk, but instead use pr_*.

         - A few Kconfig and defconfig entries have been cleaned up.

   (v3) A highlight of the changes since the v2 patch set includes:

         - We've split out all our drivers into separate patch sets,
           which I've already sent out to the relevant maintainers. I
           haven't included those patches in this patch set, but some of
           them are necessary to build our port.

         - The patch set is now split up differently: rather than being
           split per directory it is split per topic. Hopefully this
           will make it easier to review the port on the mailing list.
           The split is a bit rough, so you probably still want to look
           at the patch set as a whole.

         - atomic.h has been completely rewritten and is hopefully now
           correct. I've attempted to sanitize the various other memory
           model related code as well, and I think it should all be sane
           now aside from a handful of FIXMEs commented in the code.

         - We've changed the cmpexchg syscall to always exist and to not
           be multiplexed. There is also a VDSO entry for compare and
           exchange, which allows kernels with the A extension to
           execute user code without the A extension reasonably fast.

         - Our user-visible register state now contains enough space for
           the Q extension for 128-bit floating point, as well as a few
           words to allow extensibility to future ISA extensions like
           the eventual V extension for vectors.

         - A handful of driver cleanups, but these have been split into
           separate patch sets now so I won't duplicate them here.

   (v2) A highlight of the changes since the v1 patch set includes:

         - We've split out our drivers into the right places, which
           means now there's a lot more patches. I'll be submitting
           these patches to various subsystem maintainers and including
           them in any future RISC-V patch sets until they've been
           merged.

         - The SBI console driver has been completely rewritten to use
           the HVC helpers and is now significantly smaller.

         - We've begun to use weaker barriers as opposed to just the big
           "fence". There's still some work to do here, specifically:
            - We need fences in the relaxed MMIO functions.
            - The non-relaxed MMIO functions are missing R/W bits on their fences.
            - Many AMOs need the aq and rl bits set.

         - We now have thread_info in task_struct. As a result, sscratch
           now contains TP instead of SP. This was necessary because
           thread_info is no longer on the stack.

         - A few shared routines have been added that we use instead of
           creating another arch copy"

Linus Torvalds 4e4510fec4 sound updates for 4.15-rc1
There are no big surprising changes in this cycle, yet not too
 boring, either.  The biggest change from diffstat POV is the removal
 of the legacy OSS driver codes that have been already disabled for a
 long time.  This will bring a few trivial merge conflicts.
 
 As new features in ASoC side, there are two things: a new AC97 bus
 implementation and AMD Stony platform support.  Both include the
 relevant changes shared with other subsystems, e.g. AC97 MFD changes
 and DRM AMD changes.
 
 Some other highlighted topics are:
 - A bunch of USB-audio drivers got the hardening against the malicious
   device accesses with a new helper code for endpoint sanity check.
 - Lots of cleanups for ASoC Intel platform code, including support for
   their open source audio firmware.
 - Continued ASoC core componentization works.
 - Support for scaling MCLK with sample rate in ASoC simple-card.
 - Stabler PCM hot-unplug capability, especially for ASoC usages.

Linus Torvalds 6aa2f9441f This is the bulk of GPIO changes for the v4.15 kernel cycle:
CORE:
 - Fix the semantics of raw GPIO to actually be raw. No
   inversion semantics as before, but also no open draining,
   and allow the raw operations to affect lines used for
   interrupts as the caller supposedly knows what they are
   doing if they are getting the big hammer.
 
 - Rewrote the __inner_function() notation calls to names that
   make more sense. I just find this kind of code disturbing.
 
 - Drop the .irq_base() field from the gpiochip since now all
   IRQs are mapped dynamically. This is nice.
 
 - Support for .get_multiple() in the core driver API. This
   allows us to read several GPIO lines with a single
   register read. This has high value for some usecases: it
   can be used to create oscilloscopes and signal analyzers
   and other things that rely on reading several lines at
   exactly the same instant. Also a generally nice
   optimization. This uses the new assign_bit() macro from
   the bitops lib that was ACKed by Andrew Morton and
   is implemented for two drivers, one of them being the
   generic MMIO driver so everyone using that will be able
   to benefit from this.
 
 - Do not allow requests of Open Drain and Open Source
   setting of a GPIO line simultaneously. If the hardware
   actually supports enabling both at the same time the
   electrical result would be disastrous.
 
 - A new interrupt chip core helper. This will be helpful
   to deal with "banked" GPIOs, which means GPIO controllers
   with several logical blocks of GPIO inside them. This
   is several gpiochips per device in the device model, in
   contrast to the case when there is a 1-to-1 relationship
   between a device and a gpiochip.
 
 NEW DRIVERS:
 
 - Maxim MAX3191x industrial serializer, a very interesting
   piece of professional I/O hardware.
 
 - Uniphier GPIO driver. This is the GPIO block from the
   recent Socionext (ex Fujitsu and Panasonic) platform.
 
 - Tegra 186 driver. This is based on the new banked GPIO
   infrastructure.
 
 OTHER IMPROVEMENTS:
 
 - Some documentation improvements.
 
 - Wakeup support for the DesignWare DWAPB GPIO controller.
 
 - Reset line support on the DesignWare DWAPB GPIO controller.
 
 - Several non-critical bug fixes and improvements for the
   Broadcom BRCMSTB driver.
 
 - Misc non-critical bug fixes like exotic errorpaths, removal
   of dead code etc.
 
 - Explicit comments on fall-through switch() statements.

     to read several GPIO lines with a single register read. This has
     high value for some usecases: it can be used to create
     oscilloscopes and signal analyzers and other things that rely on
     reading several lines at exactly the same instant. Also a generally
     nice optimization. This uses the new assign_bit() macro from the
     bitops lib that was ACKed by Andrew Morton and is implemented for
     two drivers, one of them being the generic MMIO driver so everyone
     using that will be able to benefit from this.

   - Do not allow requests of Open Drain and Open Source setting of a
     GPIO line simultaneously. If the hardware actually supports
     enabling both at the same time the electrical result would be
     disastrous.

   - A new interrupt chip core helper. This will be helpful to deal with
     "banked" GPIOs, which means GPIO controllers with several logical
     blocks of GPIO inside them. This is several gpiochips per device in
     the device model, in contrast to the case when there is a 1-to-1
     relationship between a device and a gpiochip.

  New drivers:

   - Maxim MAX3191x industrial serializer, a very interesting piece of
     professional I/O hardware.

   - Uniphier GPIO driver. This is the GPIO block from the recent
     Socionext (ex Fujitsu and Panasonic) platform.

   - Tegra 186 driver. This is based on the new banked GPIO
     infrastructure.

  Other improvements:

   - Some documentation improvements.

   - Wakeup support for the DesignWare DWAPB GPIO controller.

   - Reset line support on the DesignWare DWAPB GPIO controller.

   - Several non-critical bug fixes and improvements for the Broadcom
     BRCMSTB driver.

   - Misc non-critical bug fixes like exotic errorpaths, removal of dead
     code etc.

   - Explicit comments on fall-through switch() statements"

Pull core block layer updates from Jens Axboe:
 "This is the main pull request for block storage for 4.15-rc1.

  Nothing out of the ordinary in here, and no API changes or anything
  like that. Just various new features for drivers, core changes, etc.
  In particular, this pull request contains:

   - A patch series from Bart, closing the whole on blk/scsi-mq queue
     quescing.

   - A series from Christoph, building towards hidden gendisks (for
     multipath) and ability to move bio chains around.

     (Javier, Hans, and Rakesh).

   - Removal of unused bio/bvec kmap atomic interfaces (me, Christoph)

   - Writeback series that fix the much discussed hundreds of millions
     of sync-all units. This goes all the way, as discussed previously
     (me).

   - Fix for missing wakeup on writeback timer adjustments (Yafang
     Shao).

   - Fix laptop mode on blk-mq (me).

   - {mq,name} tupple lookup for IO schedulers, allowing us to have
     alias names. This means you can use 'deadline' on both !mq and on
     mq (where it's called mq-deadline). (me).

   - blktrace race fix, oopsing on sg load (me).

   - blk-mq optimizations (me).

   - Obscure waitqueue race fix for kyber (Omar).

   - NBD fixes (Josef).

   - Disable writeback throttling by default on bfq, like we do on cfq
     (Luca Miccio).

   - Series from Ming that enable us to treat flush requests on blk-mq
     like any other request. This is a really nice cleanup.

   - Series from Ming that improves merging on blk-mq with schedulers,
     getting us closer to flipping the switch on scsi-mq again.

   - BFQ updates (Paolo).

   - blk-mq atomic flags memory ordering fixes (Peter Z).

   - Loop cgroup support (Shaohua).

   - Lots of minor fixes from lots of different folks, both for core and

Linus Torvalds bd2cd7d5a8 Power management updates for v4.15-rc1
- Relocate the OPP (Operating Performance Points) framework to its
    own directory under drivers/ and add support for power domain
    performance states to it (Viresh Kumar).
 
  - Modify the PM core, the PCI bus type and the ACPI PM domain to
    support power management driver flags allowing device drivers to
    specify their capabilities and preferences regarding the handling
    of devices with enabled runtime PM during system suspend/resume
    and clean up that code somewhat (Rafael Wysocki, Ulf Hansson).
 
  - Add frequency-invariant accounting support to the task scheduler
    on ARM and ARM64 (Dietmar Eggemann).
 
  - Fix PM QoS device resume latency framework to prevent "no
    restriction" requests from overriding requests with specific
    requirements and drop the confusing PM_QOS_FLAG_REMOTE_WAKEUP
    device PM QoS flag (Rafael Wysocki).
 
  - Drop legacy class suspend/resume operations from the PM core
    and drop legacy bus type suspend and resume callbacks from
    ARM/locomo (Rafael Wysocki).
 
  - Add min/max frequency support to devfreq and clean it up
    somewhat (Chanwoo Choi).
 
  - Rework wakeup support in the generic power domains (genpd)
    framework and update some of its users accordingly (Geert
    Uytterhoeven).
 
  - Convert timers in the PM core to use timer_setup() (Kees Cook).
 
  - Add support for exposing the SLP_S0 (Low Power S0 Idle)
    residency counter based on the LPIT ACPI table on Intel
    platforms (Srinivas Pandruvada).
 
  - Add per-CPU PM QoS resume latency support to the ladder cpuidle
    governor (Ramesh Thomas).
 
  - Fix a deadlock between the wakeup notify handler and the
    notifier removal in the ACPI core (Ville Syrjälä).
 
  - Fix a cpufreq schedutil governor issue causing it to use
    stale cached frequency values sometimes (Viresh Kumar).
 
  - Fix an issue in the system suspend core support code causing
    wakeup events detection to fail in some cases (Rajat Jain).
 
  - Fix the generic power domains (genpd) framework to prevent
    the PM core from using the direct-complete optimization with
    it as that is guaranteed to fail (Ulf Hansson).
 
  - Fix a minor issue in the cpuidle core and clean it up a bit
    (Gaurav Jindal, Nicholas Piggin).
 
  - Fix and clean up the intel_idle and ARM cpuidle drivers (Jason
    Baron, Len Brown, Leo Yan).
 
  - Fix a couple of minor issues in the OPP framework and clean it
    up (Arvind Yadav, Fabio Estevam, Sudeep Holla, Tobias Jordan).
 
  - Fix and clean up some cpufreq drivers and fix a minor issue in
    the cpufreq statistics code (Arvind Yadav, Bhumika Goyal, Fabio
    Estevam, Gautham Shenoy, Gustavo Silva, Marek Szyprowski, Masahiro
    Yamada, Robert Jarzmik, Zumeng Chen).
 
  - Fix minor issues in the system suspend and hibernation core, in
    power management documentation and in the AVS (Adaptive Voltage
    Scaling) framework (Helge Deller, Himanshu Jha, Joe Perches,
    Rafael Wysocki).

Pull power management updates from Rafael Wysocki:
 "There are no real big ticket items here this time.

  The most noticeable change is probably the relocation of the OPP
  (Operating Performance Points) framework to its own directory under
  drivers/ as it has grown big enough for that. Also Viresh is now going
  to maintain it and send pull requests for it to me, so you will see
  this change in the git history going forward (but still not right
  now).

  Another noticeable set of changes is the modifications of the PM core,
  the PCI subsystem and the ACPI PM domain to allow of more integration
  between system-wide suspend/resume and runtime PM. For now it's just a
  way to avoid resuming devices from runtime suspend unnecessarily
  during system suspend (if the driver sets a flag to indicate its
  readiness for that) and in the works is an analogous mechanism to
  allow devices to stay suspended after system resume.

  In addition to that, we have some changes related to supporting
  frequency-invariant CPU utilization metrics in the scheduler and in
  the schedutil cpufreq governor on ARM and changes to add support for
  device performance states to the generic power domains (genpd)
  framework.

  The rest is mostly fixes and cleanups of various sorts.

  Specifics:

   - Relocate the OPP (Operating Performance Points) framework to its
     own directory under drivers/ and add support for power domain
     performance states to it (Viresh Kumar).

   - Modify the PM core, the PCI bus type and the ACPI PM domain to
     support power management driver flags allowing device drivers to
     specify their capabilities and preferences regarding the handling
     of devices with enabled runtime PM during system suspend/resume and
     clean up that code somewhat (Rafael Wysocki, Ulf Hansson).

   - Add frequency-invariant accounting support to the task scheduler on
     ARM and ARM64 (Dietmar Eggemann).

   - Fix PM QoS device resume latency framework to prevent "no
     restriction" requests from overriding requests with specific
     requirements and drop the confusing PM_QOS_FLAG_REMOTE_WAKEUP
     device PM QoS flag (Rafael Wysocki).

   - Drop legacy class suspend/resume operations from the PM core and
     drop legacy bus type suspend and resume callbacks from ARM/locomo
     (Rafael Wysocki).

   - Add min/max frequency support to devfreq and clean it up somewhat
     (Chanwoo Choi).

   - Rework wakeup support in the generic power domains (genpd)
     framework and update some of its users accordingly (Geert
     Uytterhoeven).

   - Convert timers in the PM core to use timer_setup() (Kees Cook).

   - Add support for exposing the SLP_S0 (Low Power S0 Idle) residency
     counter based on the LPIT ACPI table on Intel platforms (Srinivas
     Pandruvada).

   - Add per-CPU PM QoS resume latency support to the ladder cpuidle
     governor (Ramesh Thomas).

   - Fix a deadlock between the wakeup notify handler and the notifier
     removal in the ACPI core (Ville Syrjälä).

   - Fix a cpufreq schedutil governor issue causing it to use stale
     cached frequency values sometimes (Viresh Kumar).

   - Fix an issue in the system suspend core support code causing wakeup
     events detection to fail in some cases (Rajat Jain).

   - Fix the generic power domains (genpd) framework to prevent the PM
     core from using the direct-complete optimization with it as that is
     guaranteed to fail (Ulf Hansson).

   - Fix a minor issue in the cpuidle core and clean it up a bit (Gaurav
     Jindal, Nicholas Piggin).

   - Fix and clean up the intel_idle and ARM cpuidle drivers (Jason
     Baron, Len Brown, Leo Yan).

   - Fix a couple of minor issues in the OPP framework and clean it up
     (Arvind Yadav, Fabio Estevam, Sudeep Holla, Tobias Jordan).

   - Fix and clean up some cpufreq drivers and fix a minor issue in the
     cpufreq statistics code (Arvind Yadav, Bhumika Goyal, Fabio
     Estevam, Gautham Shenoy, Gustavo Silva, Marek Szyprowski, Masahiro
     Yamada, Robert Jarzmik, Zumeng Chen).

   - Fix minor issues in the system suspend and hibernation core, in
     power management documentation and in the AVS (Adaptive Voltage
     Scaling) framework (Helge Deller, Himanshu Jha, Joe Perches, Rafael
     Wysocki).

   - Fix some issues in the cpupower utility and document that Shuah
     Khan is going to maintain it going forward (Prarit Bhargava, Shuah
     Khan)"

Linus Torvalds 2bcc673101 Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Thomas Gleixner:
 "Yet another big pile of changes:

   - More year 2038 work from Arnd slowly reaching the point where we
     need to think about the syscalls themself.

   - A new timer function which allows to conditionally (re)arm a timer
     only when it's either not running or the new expiry time is sooner
     than the armed expiry time. This allows to use a single timer for
     multiple timeout requirements w/o caring about the first expiry
     time at the call site.

   - A new NMI safe accessor to clock real time for the printk timestamp
     work. Can be used by tracing, perf as well if required.

   - A large number of timer setup conversions from Kees which got
     collected here because either maintainers requested so or they
     simply got ignored. As Kees pointed out already there are a few
     trivial merge conflicts and some redundant commits which was
     unavoidable due to the size of this conversion effort.

   - Avoid a redundant iteration in the timer wheel softirq processing.

   - Provide a mechanism to treat RTC implementations depending on their
     hardware properties, i.e. don't inflict the write at the 0.5
     seconds boundary which originates from the PC CMOS RTC to all RTCs.
     No functional change as drivers need to be updated separately.

   - The usual small updates to core code clocksource drivers. Nothing
     really exciting"

Linus Torvalds f3573b8f90 OpenRISC updates for v4.15
Small Things:
  - Move OpenRISC docs into Documentation and clean them up
  - Document previously undocumented devicetree bindings
  - Update the or1ksim dts to use stdout-path
 
 OpenRISC SMP support details:
  - First the "use shadow registers" and "define CPU_BIG_ENDIAN as true"
    get the architecture ready for SMP.
  - The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and
    qrwlocks" add the SMP locking infrastructure as needed.  Using the
    qspinlocks and qrwlocks as suggested by Peter Z while reviewing the
    original spinlocks implementation.
  - The "support for ompic" adds a new irqchip device which is used for
    IPI communication to support SMP.
  - The "initial SMP support" adds smp.c and makes changes to all of the
    necessary data-structures to be per-cpu.
  - The remaining patches are bug fixes and debug helpers which I wanted
    to keep separate from the "initial SMP support" in order to allow them
    to be reviewed on their own. This includes:
     - add cacheflush support to fix icache aliasing
     - fix initial preempt state for secondary cpu tasks
     - sleep instead of spin on secondary wait
     - support framepointers and STACKTRACE_SUPPORT
     - enable LOCKDEP_SUPPORT and irqflags tracing
     - timer sync: Add tick timer sync logic
     - fix possible deadlock in timer sync, pointed out by mips guys
 
 Note: the irqchip patch was reviewed with Marc and we agreed to push it
 together with these patches.
