Pull GPIO fix from Linus Walleij:
"A single lockdep fix, nothing else going on. This makes lockdep
noiseless and work properly with threaded GPIO IRQchips.
Summary:
Fix a lockdep issue: the threaded irqchips also need their unique key,
and take this opportunity to get rid of the horrible macro and replace
it with a static inline"

Pull drm fixes from Dave Airlie:
"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"

The ucounts_lock is being used to protect various ucounts lifecycle
management functionalities. However, those services can also be invoked
when a pidns is being freed in an RCU callback (e.g. softirq context).
This can lead to deadlocks. There were already efforts trying to
prevent similar deadlocks in add7c65ca426 ("pid: fix lockdep deadlock
warning due to ucount_lock"), however they just moved the context
from hardirq to softrq. Fix this issue once and for all by explictly
making the lock disable irqs altogether.
Dmitry Vyukov <dvyukov@google.com> reported:

a single fix for a FE hang after IOVA rollover on GC3000. This isn't
pretty, but is the minimal fix for the issue. A larger rework of the

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.

"Here are a few small USB fixes for 4.10-rc5.
Most of these are gadget/dwc2 fixes for reported issues, all of these

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

That last patch hasn't been in linux-next yet due to the weekend

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"

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.

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().
