Dave Airlie 7ec27233e6 Merge branch 'drm-next-4.12' of git://people.freedesktop.org/~agd5f/linux into drm-next 
Fixes for 4.12.  This is a bit bigger than usual since it's 3 weeks
worth of fixes and most of these changes are for vega10 which is
new for 4.12 and still in a fair amount of flux.  It looks like
you missed my last pull request, so those patches are included here
as well.  Highlights:
- Lots of vega10 fixes
- Fix interruptable wait mixup
- Fan control method fixes
- Misc display fixes for radeon and amdgpu
- Misc bug fixes

* 'drm-next-4.12' of git://people.freedesktop.org/~agd5f/linux: (132 commits)
  drm/amd/powerplay: refine pwm1_enable callback functions for CI.

Linus Torvalds 791a9a666d Merge tag 'kbuild-uapi-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild 
Pull Kbuild UAPI updates from Masahiro Yamada:
 "Improvement of headers_install by Nicolas Dichtel.

  It has been long since the introduction of uapi directories, but the
  de-coupling of exported headers has not been completed. Headers listed
  in header-y are exported whether they exist in uapi directories or
  not. His work fixes this inconsistency.

  All (and only) headers under uapi directories are now exported. The
  asm-generic wrappers are still exceptions, but this is a big step
  forward"

Linus Torvalds a2d9214c73 Merge tag 'armsoc-tee' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 
Pull TEE driver infrastructure and OP-TEE drivers from Arnd Bergmann:
 "This introduces a generic TEE framework in the kernel, to handle
  trusted environemtns (security coprocessor or software implementations
  such as OP-TEE/TrustZone). I'm sending it separately from the other
  arm-soc driver changes to give it a little more visibility, once the
  subsystem is merged, we will likely keep this in the arm₋soc drivers
  branch or have the maintainers submit pull requests directly,
  depending on the patch volume.

  I have reviewed earlier versions in the past, and have reviewed the
  latest version in person during Linaro Connect BUD17.

  Here is my overall assessment of the subsystem:

   - There is clearly demand for this, both for the generic
     infrastructure and the specific OP-TEE implementation.

   - The code has gone through a large number of reviews, and the review
     comments have all been addressed, but the reviews were not coming
     up with serious issues any more and nobody volunteered to vouch for
     the quality.

   - The user space ioctl interface is sufficient to work with the
     OP-TEE driver, and it should in principle work with other TEE
     implementations that follow the GlobalPlatform[1] standards, but it
     might need to be extended in minor ways depending on specific
     requirements of future TEE implementations

   - The main downside of the API to me is how the user space is tied to
     the TEE implementation in hardware or firmware, but uses a generic
     way to communicate with it. This seems to be an inherent problem
     with what it is trying to do, and I could not come up with any
     better solution than what is implemented here.

  For a detailed history of the patch series, see

    https://lkml.org/lkml/2017/3/10/1277"

Nicolas Dichtel fcc8487d47 uapi: export all headers under uapi directories 
Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):
asm-arc/kvm_para.h
asm-arc/ucontext.h

exported directories (like .install or .install.cmd).

Thanks to Julien Floret <julien.floret@6wind.com> for the tip to get all
subdirs with a pure makefile command.

For the record, note that exported files for asm directories are a mix of
files listed by:
 - include/uapi/asm-generic/Kbuild.asm;
 - arch/<arch>/include/uapi/asm/Kbuild;
 - arch/<arch>/include/asm/Kbuild.

Linus Torvalds 3341713c67 Merge tags 'for-linus' and 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma 
Pull more rdma updates from Doug Ledford:
 "As mentioned in my first pull request, this is the subsequent pull
  requests I had. This is all I have, and in fact this cleans out the
  RDMA subsystem's entire patchworks queue of kernel changes that are
  ready to go (well, it did for the weekend anyway, a few new patches
  are in, but they'll be coming during the -rc cycle).

  The first tag contains a single patch that would have conflicted if
  taken from my tree or DaveM's tree as it needed our trees merged to
  come cleanly.

  The second tag contains the patch series from Intel plus three other
  stragllers that came in late last week. I took them because it allowed
  me to legitimately claim that the RDMA patchworks queue was, for a
  short time, 100% cleared of all waiting kernel patches, woohoo! :-).

  I have it under my for-next tag, so it did get 0day and linux- next
  over the end of last week, and linux-next did show one minor conflict.

  Summary:

  'for-linus' tag:
   - mlx5/IPoIB fixup patch

  'for-next' tag:
   - the hfi1 15 patch set that landed late
   - IPoIB get_link_ksettings which landed late because I asked for a
     respin
   - one late rxe change

Linus Torvalds 53ef7d0e20 Merge tag 'libnvdimm-for-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm 
Pull libnvdimm updates from Dan Williams:
 "The bulk of this has been in multiple -next releases. There were a few
  late breaking fixes and small features that got added in the last
  couple days, but the whole set has received a build success
  notification from the kbuild robot.

  Change summary:

   - Region media error reporting: A libnvdimm region device is the
     parent to one or more namespaces. To date, media errors have been
     reported via the "badblocks" attribute attached to pmem block
     devices for namespaces in "raw" or "memory" mode. Given that
     namespaces can be in "device-dax" or "btt-sector" mode this new
     interface reports media errors generically, i.e. independent of
     namespace modes or state.

     This subsequently allows userspace tooling to craft "ACPI 6.1
     Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error"
     requests and submit them via the ioctl path for NVDIMM root bus
     devices.

   - Introduce 'struct dax_device' and 'struct dax_operations': Prompted
     by a request from Linus and feedback from Christoph this allows for
     dax capable drivers to publish their own custom dax operations.
     This fixes the broken assumption that all dax operations are
     related to a persistent memory device, and makes it easier for
     other architectures and platforms to add customized persistent
     memory support.

   - 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is
     available for storage appliance applications to manually trigger
     memory controllers to drain write-pending buffers that would
     otherwise be flushed automatically by the platform ADR
     (asynchronous-DRAM-refresh) mechanism at a power loss event.
     Support for "locked" DIMMs is included to prevent namespaces from
     surfacing when the namespace label data area is locked. Finally,
     fixes for various reported deadlocks and crashes, also tagged for
     -stable.

   - ACPI / nfit driver updates: General updates of the nfit driver to
     add DSM command overrides, ACPI 6.1 health state flags support, DSM
     payload debug available by default, and various fixes.

   - Support for CAPI cards on Power9, using the "Coherent Accelerator
     Interface Architecture 2.0".

   - The ability to configure the mmap randomisation limits at build and
     runtime.

   - Several small fixes and cleanups to the kprobes code, as well as
     support for KPROBES_ON_FTRACE.

   - Major improvements to handling of system reset interrupts,
     correctly treating them as NMIs, giving them a dedicated stack and
     using a new hypervisor call to trigger them, all of which should
     aid debugging and robustness.

   - Many fixes and other minor enhancements.

drm/tegra: Changes for v4.12-rc1

This contains various fixes to the host1x driver as well as a plug for a
leak of kernel pointers to userspace.

A fairly big addition this time around is the Video Image Composer (VIC)
support that can be used to accelerate some 2D and image compositing
operations.

Furthermore the driver now supports FB modifiers, so we no longer rely
on a custom IOCTL to set those.

Finally this contains a few preparatory patches for Tegra186 support
which unfortunately didn't quite make it this time, but will hopefully
be ready for v4.13.
