510353a637 drm/bridge: analogix dp: Fix runtime PM state in get_modes() callback
get_modes() callback might be called asynchronously from the DRM core and
it is not synchronized with bridge_enable(), which sets proper runtime PM
state of the main DP device. Fix this by calling pm_runtime_get_sync()
before calling drm_get_edid(), which in turn calls drm_dp_i2c_xfer() and
analogix_dp_transfer() to ensure that main DP device is runtime active
when doing any access to its registers.

This fixes the following kernel issue on Samsung Exynos5250 Snow board:

7a8b705350 Revert "drm/i915: Display WA #1133 WaFbcSkipSegments:cnl, glk"
This reverts commit 8f067837c4.

HSD says "WA withdrawn. It was causing corruption with some images.
WA is not strictly necessary since this bug just causes loss of FBC
compression with some sizes and images, but doesn't break anything."

5bfd40139d drm/vc4: Fix false positive WARN() backtrace on refcount_inc() usage
With CONFIG_REFCOUNT_FULL enabled, refcount_inc() complains when it's
passed a refcount object that has its counter set to 0. In this driver,
this is a valid use case since we want to increment ->usecnt only when
the BO object starts to be used by real HW components and this is
definitely not the case when the BO is created.

Fix the problem by using refcount_inc_not_zero() instead of
refcount_inc() and fallback to refcount_set(1) when
refcount_inc_not_zero() returns false. Note that this 2-steps operation
is not racy here because the whole section is protected by a mutex
which guarantees that the counter does not change between the
refcount_inc_not_zero() and refcount_set() calls.

ef78970ace drm/i915: Call i915_gem_init_userptr() before taking struct_mutex
We don't need struct_mutex to initialise userptr (it just allocates a
workqueue for itself etc), but we do need struct_mutex later on in
i915_gem_init() in order to feed requests onto the HW.

This should break the chain

120a264f9c drm/exynos: gem: Drop NONCONTIG flag for buffers allocated without IOMMU
When no IOMMU is available, all GEM buffers allocated by Exynos DRM driver
are contiguous, because of the underlying dma_alloc_attrs() function
provides only such buffers. In such case it makes no sense to keep
BO_NONCONTIG flag for the allocated GEM buffers. This allows to avoid
failures for buffer contiguity checks in the subsequent operations on GEM
objects.

Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Wed Dec 14 00:08:06 2016 +0100

    drm: locking&new iterators for connector_list

we've went to extreme lengths to make sure connector iterations works
in any context, without introducing any additional locking context.
This worked, except for a small fumble in the implementation:

When we actually race with a concurrent connector unplug event, and
our temporary connector reference turns out to be the final one, then
everything breaks: We call the connector release function from
whatever context we happen to be in, which can be an irq/atomic
context. And connector freeing grabs all kinds of locks and stuff.

Fix this by creating a specially safe put function for connetor_iter,
which (in this rare case) punts the cleanup to a worker.

a87e55f89f drm/i915: Fix vblank timestamp/frame counter jumps on gen2
Previously I was under the impression that the scanline counter
reads 0 when the pipe is off. Turns out that's not correct, and
instead the scanline counter simply stops when the pipe stops, and
it retains it's last value until the pipe starts up again, at which
point the scanline counter jumps to vblank start.

These jumps can cause the timestamp to jump backwards by one frame.
Since we use the timestamps to guesstimage also the frame counter
value on gen2, that would cause the frame counter to also jump
backwards, which leads to a massice difference from the previous value.
The end result is that flips/vblank events don't appear to complete as
they're stuck waiting for the frame counter to catch up to that massive
difference.

Fix the problem properly by actually making sure the scanline counter
has started to move before we assume that it's safe to enable vblank
processing.

Merge tag 'at24-4.15-fixes-for-wolfram' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into i2c/for-current

Please consider pulling the following fixes for v4.15. While it doesn't
fix any regression introduced in the v4.15 merge window, we have a
feature in at24 since linux v4.8 - reading the mac address block from
at24mac series - which turned out to be not working.

This pull request contains changes that fix it together with a patch
that hardens the read and write argument sanitization with
out-of-bounds checks that were missing.

e1ba1c99da RISC-V Cleanups and ABI Fixes for 4.15-rc2
This tag contains a handful of small cleanups that are a result of
 feedback that didn't make it into our original patch set, either because
 the feedback hadn't been given yet, I missed the original emails, or
 we weren't ready to submit the changes yet.
 
 I've been maintaining the various cleanup patch sets I have as their own
 branches, which I then merged together and signed.  Each merge commit
 has a short summary of the changes, and each branch is based on your
 latest tag (4.15-rc1, in this case).  If this isn't the right way to do
 this then feel free to suggest something else, but it seems sane to me.
 
 Here's a short summary of the changes, roughly in order of how
 interesting they are.
 
 * libgcc.h has been moved from include/lib, where it's the only member,
   to include/linux.  This is meant to avoid tab completion conflicts.
 * VDSO entries for clock_get/gettimeofday/getcpu have been added.  These
   are simple syscalls now, but we want to let glibc use them from the
   start so we can make them faster later.
 * A VDSO entry for instruction cache flushing has been added so
   userspace can flush the instruction cache.
 * The VDSO symbol versions for __vdso_cmpxchg{32,64} have been removed,
   as those VDSO entries don't actually exist.
 * __io_writes has been corrected to respect the given type.
 * A new READ_ONCE in arch_spin_is_locked().
 * __test_and_op_bit_ord() is now actually ordered.
 * Various small fixes throughout the tree to enable allmodconfig to
   build cleanly.
 * Removal of some dead code in our atomic support headers.
 * Improvements to various comments in our atomic support headers.

I've dropped patches 8 and 10 from the original set:

* [PATCH 08/10] (RISC-V: Set __ARCH_WANT_RENAMEAT to pick up generic
  version) has a better fix that I've sent out for review, we don't want
  renameat.
* [PATCH 10/10] (input: joystick: riscv has get_cycles) has already been
