0c51ef8684 drm/debugfs: Fix framebuffer debugfs file init 
The introduction of: drm/framebuffer: Add framebuffer debugfs file
broke vgem. That patch assumed that all drivers had initialized the
dev->mode_config.fb_lock mutex which happens in drm_mode_config_init().
vgem doesn't need to call drm_mode_config_init().

Fix this by only creating the framebuffer debugfs file for modesetting
drivers.

8d25ccebef drm/cma-helper: Turn to_drm_gem_cma_obj() into a macro 
This allows the argument to be a const.

The other option was to keep it an inline function and make the argument
a const:

static inline struct drm_gem_cma_object *
to_drm_gem_cma_obj(const struct drm_gem_object *gem_obj)
{
	return container_of(gem_obj, struct drm_gem_cma_object, base);
}

This will happily return a non-const pointer to the drm_gem_cma_object
based on a const pointer to the contained drm_gem_object, thus creating
const-safety problems.

There was an attempt to fix the problem in the container_of() macro
itself (see https://lkml.org/lkml/2017/5/19/381) but the patch seems to
have fallen through the cracks. It would require turning this inline
function into a macro.

By making this a macro now, we will benefit from a possible future
enhancement of container_of(). We don't loose type checking by doing
this, container_of() takes care of that.

4013e44ffa drm: qxl: remove pr_info message, stops log spamming 
Simply mmap'ing /dev/dri/card0 repeatedly will spam the kernel
log with qxl_mmap information messages. The following example code
illustrates this:

int main(void)
{
	int fd = open("/dev/dri/card0", O_RDONLY);
	if (fd == -1)
		err(1, "open failed");

	for (;;) {
		void *m = mmap(NULL, 4096, PROT_READ,
			MAP_SHARED, fd, 0);
		if (m != MAP_FAILED)
			munmap(m, 4096);
	}
}

Stop the spamming by removing the pr_info message. Since the mmap'ing
returns -EINVAL there is no need for the pr_info message.

846c7dfc11 drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2. 
This introduces a slight behavioral change to rmfb. Instead of
disabling a crtc when the primary plane is disabled, we try to
preserve it.

Apart from old versions of the vmwgfx xorg driver, there is
nothing depending on rmfb disabling a crtc.

Vmwgfx' and simple kms helper atomic implementation rejects CRTC
enabled without plane, so we can do this safely.

If the atomic commit is rejected by the driver then we will still
fall back to the old behavior and turn off the crtc.

Changes since v1:
- Restart completely when rmfb with crtc on fails (Sean Paul).

d471ed04b4 drm/drivers: drop redundant drm_edid_to_eld() calls 
drm_add_edid_modes() now fills in the ELD automatically, so the calls to
drm_edid_to_eld() are redundant. Remove them.

All the other places are obvious, but nv50 has detached
drm_edid_to_eld() from the drm_add_edid_modes() call.

1d1c366507 drm/edid: set ELD connector type in drm_edid_to_eld() 
Since drm_edid_to_eld() knows the connector type, we can set the type in
ELD while at it. Most connectors this gets called on are not DP
encoders, and with the HDMI type being 0, this does not change behaviour
for non-DP.

For i915 having this in place earlier would have saved a considerable
amount of debugging that lead to the fix 2d8f63297b ("drm/i915: always
update ELD connector type after get modes"). I don't see other drivers,
even the ones calling drm_edid_to_eld() on DP connectors, setting the
connector type in ELD.

de7e8bd01a drm: via: use ktime_get() instead of do_gettimeofday 
We want to remove uses of do_gettimeofday() from the kernel since the
resulting timeval structure overflows in 2038. This is not a problem for
this particular use, but do_gettimeofday() is also not an appropriate
method for measuring time intervals, since it requires a conversion into
microseconds and is complicated to work with.

ktime_get() is a better replacement, as it works with the monontonic
kernel timebase and requires a minimum of computation.

I'm slightly changing the output from microseconds to nanoseconds here,
to avoid introducing a new division operation. This should be fine
since the value is only used for debugging.
