f7f6634d23 virtio_mmio: Set DMA masks appropriately
Once DMA API usage is enabled, it becomes apparent that virtio-mmio is
inadvertently relying on the default 32-bit DMA mask, which leads to
problems like rapidly exhausting SWIOTLB bounce buffers.

Ensure that we set the appropriate 64-bit DMA mask whenever possible,
with the coherent mask suitably limited for the legacy vring as per
a0be1db430 ("virtio_pci: Limit DMA mask to 44 bits for legacy virtio
devices").

 "drm fixes across the board.

  Okay holidays and LCA kinda caught up with me, I thought I'd get some
  of this dequeued last week, but Hobart was sunny and warm and not all
  gloomy and rainy as usual.

  This is a bit large, but not too much considering it's two weeks stuff
  from AMD and Intel.

  core:
   - one locking fix that helps with dynamic suspend/resume races

  i915:
   - mostly GVT updates, GVT was a recent introduction so fixes for it
     shouldn't cause any notable side effects.

  amdgpu:
   - a bunch of fixes for GPUs with a different memory controller design
     that need different firmware.

  exynos:
   - decon regression fixes

  msm:
   - two regression fixes

  etnaviv:
   - a workaround for an mmu bug that needs a lot more work.

  virtio:
   - sparse fix, and a maintainers update"

cfee5d6376 platform/x86: ideapad-laptop: handle ACPI event 1
On Ideapad laptops, ACPI event 1 is currently not handled. Many models
log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while
running on battery power. Some convertible laptops receive this event
when switching in and out of tablet mode.

This adds and additional case for event 1 in ideapad_acpi_notify to call
ideapad_input_report(priv, vpc_bit), so that the event is reported to
userspace and we avoid unnecessary logging.

c497f8d172 USB fixes for 4.10-rc5
Here are a few small USB fixes for 4.10-rc5.
 
 Most of these are gadget/dwc2 fixes for reported issues, all of these
 have been in linux-next for a while.  The last one is a single xhci
 WARN_ON removal to handle an issue that the dwc3 driver is hitting in
 the 4.10-rc tree.  The warning is harmless and needs to be removed, and
 a "real" fix that is more complex will show up in 4.11-rc1 for this
 device.
 
 That last patch hasn't been in linux-next yet due to the weekend timing,
 but it's a "simple" WARN_ON() removal so what could go wrong?  :)

Pull libnvdimm fixes from Dan Williams:
 "Two fixes:

   - a regression fix for the multiple-pmem-namespace-per-region support
     added in 4.9. Even if an existing environment is not using that
     feature the act of creating and a destroying a single namespace
     with the ndctl utility will lead to the proliferation of extra
     unwanted namespace devices.

   - a fix for the error code returned from the pmem driver when the
     memcpy_mcsafe() routine returns -EFAULT. Btrfs seems to be the only
     block I/O consumer that tries to parse the meaning of the error
     code when it is non-zero.

  Neither of these fixes are critical, the namespace leak is awkward in
  that it can cause device naming to change and complicates debugging
  namespace initialization issues. The error code fix is included out of
  caution for what other consumers might be expecting -EIO for block I/O
  errors"

Date:   Thu Aug 4 16:32:25 2016 +0100

    drm/i915: Split insertion/binding of an object into the VM

It is useful to have this trace as it pairs nicely with the vma_unbind
one to track vma activity.
Added inside the i915_vma_bind function (was outside before) to keep a
similar placement as trace_i915_vma_unbind.

v2: print bind_flags instead of flags (Chris)

  - The R-Car patches adding fallbacks are just adding new compatible
    strings to the driver so that device trees are written in a more
    robustly future proof fashion, this isn't strictly a fix but it's
    just new IDs and it's better to get it into mainline sooner to

  - The DesignWare "switch to new API part 2" patch is actually a

f09ff1de63 SCSI fixes on 20170119
This is a set of 12 fixes including the mpt3sas one that was causing
 hangs on ATA passthrough.  The others are a couple of zoned block
 device fixes, a SAS device detection bug which lead to SATA drives not
 being matched to bays, two qla2xxx MSI fixes, a qla2xxx req for rsp
 confusion caused by cut and paste, and a few other minor fixes.

488dc16491 xhci: remove WARN_ON if dma mask is not set for platform devices
The warn on is a bit too much, we will anyway set the dma mask if not set
previously.

The main reason for this fix is that 4.10-rc1  has a dwc3 change that
pass a parent sysdev dev pointer instead of setting the dma mask of
its xhci platform device. xhci platform driver can then get more
attributes from the sysdev than just the dma mask.

The usb core and xhci changes are not yet in 4.10, and a fix like
this was preferred instead of taking those big changes this late in
the rc-cycle.

7e79a6836c drm/i915: Set adjustment to zero on Up/Down interrupts if freq is already max/min
When we reach the user's RPS limits, stop requesting an adjustment. Even
though we will clamp the requested frequency later, we rely on interrupt
masking to disable further adjustments in the same direction. Even
though it is unlikely (one scenario is a bug in the driver, another is
careful manipulation through the uAPI) if we keep exponentially
increasing the adjustment value, it will wrap and cause a negative
adjustment.

7d3ce5ab94 virtio/s390: support READ_STATUS command for virtio-ccw
As virtio-1 introduced the possibility of the device manipulating the
status byte, revision 2 of the virtio-ccw transport introduced a means
of getting the status byte from the device via READ_STATUS. Let's wire
it up for revisions >= 2 and fall back to returning the stored status
byte if not supported.
