 "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"

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"

KVM: s390: Fix for 4.10 (via kvm/master)

Fix a kernel memory exposure.

kvm_s390_get_machine() populates the facility bitmap by copying bytes
from the host results that are stored in a 256 byte array in the prefix
page. The KVM code does use the size of the target buffer (2k), thus
copying and exposing unrelated kernel memory (mostly machine check
related logout data).

Let's use the size of the source buffer instead.  This is ok, as the
target buffer will always be greater or equal than the source buffer as
the KVM internal buffers (and thus S390_ARCH_FAC_LIST_SIZE_BYTE) cover
the maximum possible size that is allowed by STFLE, which is 256
doublewords. All structures are zero allocated so we can leave bytes
256-2047 unchanged.

Add a similar fix for kvm_arch_init_vm().

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.

IBM bit 31 (for the rest of us - bit 0) is a reserved field in the
instruction definition of mtspr and mfspr. Hardware is encouraged to
(and does) ignore it.

As a result, if userspace executes an mtspr DSCR with the reserved bit
set, we get a DSCR facility unavailable exception. The kernel fails to
match against the expected value/mask, and we silently return to
userspace to try and re-execute the same mtspr DSCR instruction. We
loop forever until the process is killed.

We should do something here, and it seems mirroring what hardware does
is the better option vs killing the process. While here, relax the
matching of mfspr PVR too.

Pull ARM SoC fixes from Olof Johansson:

  noteworthy, for the most part it's a large collection of small DT
  tweaks"
