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.

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

  work to be done optimising things like exception return, but the ABI
  is solid now.

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"

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.

   - adding a sbs-manager based on I2C core updates to SMBus alerts
     (touching drivers/power/*)

  Other notable changes:

   - i2c_boardinfo can now carry a dev_name to be used when the device
     is created. This is because some devices in ACPI world need fixed
     names to find the regulators.

   - the designware driver got a long discussed overhaul of its PM
     handling. img-scb and davinci got PM support, too.

   - at24 driver has way better OF support. And it has a new maintainer.

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.

Merge tag 'gpio-v4.15-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "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"

   - 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

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).

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).

     Khan is going to maintain it going forward (Prarit Bhargava, Shuah
     Khan)"

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"

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.

76727c2c3b ASoC: Updates for v4.15 
The biggest thing this release has been the conversion of the AC98 bus
 to the driver model, that's been a long time coming so thanks to Robert
 Jarzmik for his dedication there.  Due to there being some AC97 MFD
 there's a few fairly large changes in input and the MFD layer, mainly to
 the wm97xx driver.
 
 There's also some drivers/drm changes to support the new AMD Stoney
 platform, these are shared with the DRM subsystem and should be being
 merged via both.
 
 Within the subsystem the overwhelming bulk of the changes is in the
 Intel drivers which continue to need lots of cleanups and fixes, this
 release they've also gained support for their open source firmware.
 There's also some large changs in the core as Morimoto-san continues to
 mirror operations into the component level in preparation for conversion
 of drivers to that.
 
  - The AC97 bus has finally caught up with the driver model thanks to
    some dedicated and persistent work from Robert Jarzmik.
  - Continued work from Morimoto-san on moving us towards being able to
    use components for everything.
  - Lots of cleanups for the Intel platform code, including support for
    their open source audio firmware.
  - Support for scaling MCLK with sample rate in simple-card.
  - Support for AMD Stoney platform.

136fc5c41f scripts: add leaking_addresses.pl 
Currently we are leaking addresses from the kernel to user space. This
script is an attempt to find some of those leakages. Script parses
`dmesg` output and /proc and /sys files for hex strings that look like
kernel addresses.

Only works for 64 bit kernels, the reason being that kernel addresses on
64 bit kernels have 'ffff' as the leading bit pattern making greping
possible. On 32 kernels we don't have this luxury.

Scripts is _slightly_ smarter than a straight grep, we check for false
positives (all 0's or all 1's, and vsyscall start/finish addresses).

[ I think there is a lot of room for improvement here, but it's already
  useful, so I'm merging it as-is. The whole "hash %p format" series is
  expected to go into 4.15, but will not fix %x users, and will not
  incentivize people to look at what they are leaking.     - Linus ]
