Error messages or debugging message reported during user-space command
submission should not be printed to dmesg by default. So add a new
preprocessor define called VMW_DEBUG_USER which translates to
DRM_DEBUG_DRIVER.
v2: Use VMW_DEBUG_USER instead of using DRM_DEBUG_DRIVER directly.

Currently we flag resources as dirty (GPU contents not yet read back to
the backing MOB) whenever they have been part of a command stream.
Obviously many resources can't be dirty and others can only be dirty when
written to by the GPU. That is when they are either bound to the context as
render-targets, depth-stencil, copy / clear destinations and
stream-output targets, or similarly when there are corresponding views into
them.
So mark resources dirty only in these special cases. Context- and cotable
resources are always marked dirty when referenced.
This is important for upcoming emulated coherent memory, since we can avoid
issuing automatic readbacks to non-dirty resources when the CPU tries to
access part of the backing MOB.
Testing: Unigine Heaven with max GPU memory set to 256MB resulting in
heavy resource thrashing.

The only bpc information in pipe registers for BXT/GLK DSI
is the PIPEMISC dither bpc. Let's try to use that to read
out pipe_bpp on these platforms. However, I'm not sure if
this will be correctly populated by the GOP since bspec
suggests it's only needed if dithering is actually enabled.
If not I guess we'll have to go one step further and
extract pipe_bpp from the DSI pixel format when dithering
is disabled.

[Why]
If the cursor pos passed from DM is less than the plane_state->dst_rect
top left corner then the unsigned cursor pos wraps around to a large
positive number since cursor pos is a u32.
There was an attempt to guard against this in hubp1_cursor_set_position
by checking the src_x_offset and src_y_offset and offseting the
cursor hotspot within hubp1_cursor_set_position.
However, the cursor position itself is still being programmed
incorrectly as a large value.
This manifests itself visually as the cursor disappearing or containing
strange artifacts near the middle of the screen on raven.
[How]
Don't subtract the destination rect top left corner from the pos but
add it to the hotspot instead. This happens before the pos gets
passed into hubp1_cursor_set_position.
This achieves the same result but avoids the subtraction wrap around.
With this fix the original cursor programming logic can be used again.
v2: add hunk that got dropped accidently when this patch was originally
committed. (Alex)

Push getting the reference for the encoders' power domains into the
encoder get_power_domains() hook instead of doing this from the caller.
This way the encoder can store away the corresponding wakerefs.
This fixes the DSI encoder disabling, which didn't release these
power references it acquired during HW state readout.
Note that longtime ownership for the corresponding wakerefs can be thus
acquired / released in two ways. Nevertheless there is always only one
owner for them:
After HW readout (booting/system resume):
- encoder->get_power_domains() acquires
- encoder->disable*() releases
After a modeset (calling intel_atomic_commit()):
- encoder->enable*() acquires
- encoder->disable*() releases
* can be any of the encoder enable/disable hooks.
v2:
- Check that the DSI io_wakerefs are unset both during encoder HW
readout and enabling. (Chris)

mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:
@mmiowb@
@@
- mmiowb();
and invoked as:
$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done
NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

sun8i_tcon_top_un/bind
There are two problems here:
1. Not all clk_data->hws[] need to be initialized, depending on various
configured quirks. This leads to NULL ptr deref in
clk_hw_unregister_gate() in sun8i_tcon_top_unbind()
2. If there is error when registering the clk_data->hws[],
err_unregister_gates error path will try to unregister
IS_ERR()=true (invalid) pointer.
For problem (1) I have this stack trace:

While transitioning to having better clarity between the modules, it's
desirable to have the function name prefixes reflect the
module. Functions in intel_foo.c should be prefixed intel_foo_.
Expose only one CDCLK init/uninit function from intel_cdclk.c instead of
one per platform. Obviously this adds one "unnecessary" if ladder within
the entry points. However it should be considered more of a CDCLK
implementation detail how this is done per platform, instead of exposing
the fact. In other words, abstract the CDCLK module better.

If we unplug a udl device, the usb callback with deinit the
mode_config struct, however userspace will still have an open
file descriptor and a framebuffer on that device. When userspace
closes the fd, we'll oops because it'll try and look stuff up
in the object idr which we've destroyed.
This punts destroying the mode objects until release time instead.

The only bpc information in pipe registers for BXT/GLK DSI
is the PIPEMISC dither bpc. Let's try to use that to read
out pipe_bpp on these platforms. However, I'm not sure if
this will be correctly populated by the GOP since bspec
suggests it's only needed if dithering is actually enabled.
If not I guess we'll have to go one step further and
extract pipe_bpp from the DSI pixel format when dithering
is disabled.

Time to kill some bad sample code people are copying from ;)
This is a complete rewrite of the cirrus driver. The cirrus_mode_set()
function is pretty much the only function which is carried over largely
unmodified. Everything else is upside down.
It is a single monster patch. But given that it does some pretty
fundamental changes to the drivers workflow and also reduces the code
size by roughly 70% I think it'll still be alot easier to review than a
longish baby-step patch series.
Changes summary:
- Given the small amout of video memory (4 MB) the cirrus device has
the rewritten driver doesn't try to manage buffers there. Instead
it will blit (memcpy) the active framebuffer to video memory.
- All gem objects are stored in main memory and are manged using the
new shmem helpers. ttm is out.
- It supports RG16, RG24 and XR24 formats. XR24 gets converted to RG24
or RG16 at blit time if needed, to avoid the pitch becoming larger
than what the cirrus hardware can handle.
- The simple display pipeline is used.
- The generic fbdev emulation is used.
- It's a atomic driver now.
- It runs wayland.

ppgtt_free_all_spt() iterates the radixtree as it is deleting it,
forgoing all protection against the leaves being freed in the process
(leaving the iter pointing into the void).
A minimal fix seems to be to use the available post_shadow_list to
decompose the tree into a list prior to destroying the radixtree.
Alerted by the sparse warnings:
