add_gpu_components() adds found GPU nodes from the DT to the match list,
regardless of the status of the nodes.  This is a problem, because if the
nodes are disabled, they should not be on the match list because they will
not be matched.  This prevents display from initing if a GPU node is
defined, but it's status is disabled.

Fix this by checking the node's status before adding it to the match list.

2bab52af6f drm/msm: add support for per-CRTC max_vblank_count on mdp5 
The mdp5 drm/kms driver currently does not work on command-mode DSI
panels due to 'vblank wait timed out' errors. This causes a latency
of seconds, or tens of seconds in some cases, before content is shown
on the panel. This hardware does not have the something that we can use
as a frame counter available when running in command mode, so we need to
fall back to using timestamps by setting the max_vblank_count to zero.
This can be done on a per-CRTC basis, so the convert mdp5 to use
drm_crtc_set_max_vblank_count().

This change was tested on a LG Nexus 5 (hammerhead) phone.

5854059457 drm/bochs: Use shadow buffer for bochs framebuffer console 
The bochs driver (and virtual hardware) requires buffer objects to
reside in video ram to display them to the screen. So it can not
display the framebuffer console because the respective buffer object
is permanently pinned in system memory.

Using a shadow buffer for the console solves this problem. The console
emulation will pin the buffer object only during updates from the shadow
buffer. Otherwise, the bochs driver can freely relocated the buffer
between system memory and video ram.

87e281f88f drm/fb-helper: Map DRM client buffer only when required 
This patch changes DRM clients to not map the buffer by default. The
buffer, like any buffer object, should be mapped and unmapped when
needed.

An unmapped buffer object can be evicted to system memory and does
not consume video ram until displayed. This allows to use generic fbdev
emulation with drivers for low-memory devices, such as ast and mgag200.

This change affects the generic framebuffer console. HW-based consoles
map their console buffer once and keep it mapped. Userspace can mmap this
buffer into its address space. The shadow-buffered framebuffer console
only needs the buffer object to be mapped during updates. While not being
updated from the shadow buffer, the buffer object can remain unmapped.
Userspace will always mmap the shadow buffer.

v2:
	* change DRM client to not map buffer by default
	* manually map client buffer for fbdev with HW framebuffer

d9b42dfab5 drm/client: Support unmapping of DRM client buffers 
DRM clients, such as the fbdev emulation, have their buffer objects
mapped by default. Mapping a buffer implicitly prevents its relocation.
Hence, the buffer may permanently consume video memory while it's
allocated. This is a problem for drivers of low-memory devices, such as
ast, mgag200 or older framebuffer hardware, which will then not have
enough memory to display other content (e.g., X11).

This patch introduces drm_client_buffer_vmap() and _vunmap(). Internal
DRM clients can use these functions to unmap and remap buffer objects
as needed.

There's no reference counting for vmap operations. Callers are expected
to either keep buffers mapped (as it is now), or call vmap and vunmap
in pairs around code that accesses the mapped memory.

v2:
	* remove several duplicated NULL-pointer checks
v3:
	* style and typo fixes

4b9bb9728c drm/i915: Only recover active engines 
If we issue a reset to a currently idle engine, leave it idle
afterwards. This is useful to excise a linkage between reset and the
shrinker. When waking the engine, we need to pin the default context
image which we use for overwriting a guilty context -- if the engine is
idle we do not need this pinned image! However, this pinning means that
waking the engine acquires the FS_RECLAIM, and so may trigger the
shrinker. The shrinker itself may need to wait upon the GPU to unbind
and object and so may require services of reset; ergo we should avoid
the engine wake up path.

The danger in skipping the recovery for idle engines is that we leave the
engine with no context defined, which may interfere with the operation of
the power context on some older platforms. In practice, we should only
be resetting an active GPU but it something to look out for on Ironlake
(if memory serves).

de70fdd7d2 drm/i915: fix possible memory leak in intel_hdcp_auth_downstream() 
'ksv_fifo' is malloced in intel_hdcp_auth_downstream() and should be
freed before leaving from the error handling cases, otherwise it will
cause memory leak.

10e36489ab drm/i915/execlists: Always clear pending&inflight requests on reset 
If we skip the reset as we found the engine inactive at the time of the
reset, we still need to clear the residual inflight & pending request
bookkeeping to reflect the current state of HW.

Otherwise, we may end up stuck in a loop like:

3de433c5b3 drm/msm: Use the correct dma_sync calls in msm_gem 
[subject was: drm/msm: shake fist angrily at dma-mapping]

So, using dma_sync_* for our cache needs works out w/ dma iommu ops, but
it falls appart with dma direct ops.  The problem is that, depending on
display generation, we can have either set of dma ops (mdp4 and dpu have
iommu wired to mdss node, which maps to toplevel drm device, but mdp5
has iommu wired up to the mdp sub-node within mdss).

Fixes this splat on mdp5 devices:
