Ben Skeggs 95664e66fa drm/nouveau/disp/dp: ensure sink is powered up before attempting link training
This can happen under some annoying circumstances, and is a quick fix
until more substantial changes can be made.

Fixed eDP mode changes on (at least) the Lenovo P50.

Rasmus Villemoes 4fbbed46dc drm/nouveau: use post-decrement in error handling
We need to use post-decrement to get the dma_map_page undone also for
i==0, and to avoid some very unpleasant behaviour if dma_map_page
failed already at i==0.

Mario Kleiner ff683df7bf drm/nouveau/display: Enable vblank irqs after display engine is on again.
In the display resume path, move the calls to drm_vblank_on()
after the point when the display engine is running again.

Since changes were made to drm_update_vblank_count() in Linux 4.4+
to emulate hw vblank counters via vblank timestamping, the function
drm_vblank_on() now needs working high precision vblank timestamping
and therefore working scanout position queries at time of call.
These don't work before the display engine gets restarted, causing
miscalculation of vblank counter increments and thereby large forward
jumps in vblank count at display resume. These jumps can cause client
hangs on resume, or desktop hangs in the case of composited desktops.

Fix this Linux 4.4 regression by reordering calls accordingly.

Linus Torvalds e3de671dd6 asm-generic changes for 4.5
The asm-generic tree this time contains one series from Nicolas Pitre
 that makes the optimized do_div() implementation from the ARM
 architecture available to all architectures. This also adds stricter
 type checking for callers of do_div, which has uncovered a number
 of bugs in existing code, and fixes up the ones we have found.

Linus Torvalds a016af2e70 sound updates for 4.5-rc1
We've had quite busy weeks in this cycle.  Looking at ALSA core, the
 significant changes are a few fixes wrt timer and sequencer ioctls
 that have been revealed by fuzzer recently.  Other than that, ASoC
 core got a few updates about DAI link handling, but these are rather
 straightforward refactoring.
 
 In drivers scene, ASoC received quite lots of new drivers in addition
 to bunch of updates for still ongoing Intel Skylake support and
 topology API.  HD-audio gained a new HDMI/DP hotplug notification via
 component.  FireWire got a pile of code refactoring/updates with
 SCS.1x driver integration.
 
 More highlights are shown below.
 
 [NOTE: this contains also many commits for DRM.  This is due to the
  pull of drm stable branch into sound tree, as the base of i915 audio
  component work for HD-audio.  The highlights below don't contain
  these DRM changes, as these are supposed to be pulled via drm tree in
  anyway sooner or later.]
 
 Core
  - Handful fixes to harden ALSA timer and sequencer ioctls against
    races reported by syzkaller fuzzer
  - Irq description string can be unique to each card; only for
    HD-audio for now
 
 ASoC
  - Conversion of the array of DAI links to a list for supporting
    dynamically adding and removing DAI links
  - Topology API enhancements to make everything more component based
    and being able to specify PCM links via topology
  - Some more fixes for the topology code, though it is still not final
    and ready for enabling in production; we really need to get to the
    point where that can be done
  - A pile of changes for Intel SkyLake drivers which hopefully deliver
    some useful initial functionality for systems with this chipset,
    though there is more work still to come
  - Lots of new features and cleanups for the Renesas drivers
  - ANC support for WM5110
  - New drivers: Imagination Technologies IPs, Atmel class D speaker,
    Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and
    RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP
  - Rename PCM1792a driver to be generic pcm179x
 
 HD-Audio
  - Use audio component for i915 HDMI/DP hotplug handling
  - On-demand binding with i915 driver
  - bdl_pos_adj parameter adjustment for Baytrail controllers
  - Enable power_save_node for CX20722; this shouldn't lead to
    regression, hopefully
  - Kabylake HDMI/DP codec support
  - Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell
    machines
  - A few code refactoring
 
 FireWire
  - Lots of code cleanup and refactoring
  - Integrate the support of SCS.1x devices into snd-oxfw driver;
    snd-scs1x driver is obsoleted
 
 USB-audio
  - Fix possible NULL dereference at disconnection
  - A regression fix for Native Instruments devices
 
 Misc
  - A few code cleanups of fm801 driver

Alexandre Courbot b306712d92 drm/nouveau/instmem/gk20a: use DMA API CPU mapping
Commit 69c4938249 ("drm/nouveau/instmem/gk20a: use direct CPU access")
tried to be smart while using the DMA-API by managing the CPU mappings of
buffers allocated with the DMA-API by itself. In doing so, it relied
on dma_to_phys() which is an architecture-private function not
available everywhere. This broke the build on several architectures.

Since there is no reliable and portable way to obtain the physical
address of a DMA-API buffer, stop trying to be smart and just use the
CPU mapping that the DMA-API can provide. This means that buffers will
be CPU-mapped for all their life as opposed to when we need them, but
anyway using the DMA-API here is a fallback for when no IOMMU is
available so we should not expect optimal behavior.

This makes the IOMMU and DMA-API implementations of instmem diverge
enough that we should maybe put them into separate files...

Alexandre Courbot 338840eed1 drm/nouveau/instmem/gk20a: fix race conditions
The LRU list used for recycling CPU mappings was handling concurrency
very poorly. For instance, if an instobj was acquired twice before being
released once, it would end up into the LRU list even though there is
still a client accessing it.

This patch fixes this by properly counting how many clients are
currently using a given instobj.

While at it, we also raise errors when inconsistencies are detected, and
factorize some code.

Nicolas Chauvet 5a9e822f80 drm/nouveau/gk20a: Add MODULE_FIRMWARE for gk20a
This patch is needed by initramfs tools to detect
the required firmware files for the module.

This patch tests for either TEGRA_124_SOC or TEGRA_132_SOC
for the firmwares related to the Tegra K1 generation.

v2: move the MODULE_FIRMWARE to the nvidia_platform.c file.
 This will avoid to test for NOUVEAU_PLATFORM_DRIVER
