<title>drm/lease: Send a distinct uevent</title>

Sending the exact same hotplug event is not great uapi. Luckily the
only already merged implementation of leases (in the -modesetting
driver) doesn't care about what kind of uevent it gets, and
unconditionally processes both hotplug and lease changes. So we can
still adjust the uapi here.

But e.g. weston tries to filter stuff, and I guess others might want
to do that too. Try to make that possible. Cc: stable since it's uapi
adjustement that we want to roll out everywhere.

Michel Dänzer mentioned on irc that -amdgpu also has lease support. It
has the same code flow as -modesetting though, so we can still go
ahead.

v2: Mention -amdgpu (Michel)

    drm: remove procfs code, take 2

Having the code shared between procfs and debugfs in the separate
drm_info.c file stopped making sense. Merge them.

Noticed because Lyude asked some questions on irc about why we even
have drm_info_node and I remember this old story.

Only needed minimal changes in drm_internal.h (for the drm_ioctl_t
type and a few forward declarations), plus a few missing includes in
drm_connector.c.

Yay, the last stage of the drm header cleanup can finally commence!

v2: Compiles now, with drm/drm_util.h extracted.

Rather than doing drm_file allocation/destruction right in the fops, lets
provide separate helpers. This decouples drm_file management from the
still-mandatory drm-fops. It prepares for use of drm_file without the
fops, both by possible separate fops implementations and APIs (not that I
am aware of any such plans), and more importantly from in-kernel use where
no real file is available.

These provide crtc-id based functions instead of pipe-number, while
also offering higher resolution time (ns) and wider frame count (64)
as required by the Vulkan API.

v2:

 * Check for DRIVER_MODESET in new crtc-based vblank ioctls

	Failing to check this will oops the driver.

 * Ensure vblank interupt is running in crtc_get_sequence ioctl

	The sequence and timing values are not correct while the
	interrupt is off, so make sure it's running before asking for
	them.

 * Short-circuit get_sequence if the counter is enabled and accurate

	Steal the idea from the code in wait_vblank to avoid the
	expense of drm_vblank_get/put

 * Return active state of crtc in crtc_get_sequence ioctl

	Might be useful for applications that aren't in charge of
	modesetting?

 * Use drm_crtc_vblank_get/put in new crtc-based vblank sequence ioctls

	Daniel Vetter prefers these over the old drm_vblank_put/get
	APIs.

 * Return s64 ns instead of u64 in new sequence event

Suggested-by: Ville Syrjälä &lt;ville.syrjala@linux.intel.com&gt;

v3:

 * Removed FIRST_PIXEL_OUT_FLAG
 * Document that the timestamp in the query and event are
   that of the first pixel leaving the display engine for
   the display (using the same wording as the Vulkan spec).

<title>drm: vblank: remove drm_timestamp_monotonic parameter</title>

There is a risk of overflowing vblank timestamps in 2038 or 2106 if
someone sets the drm_timestamp_monotonic module parameter to zero.

I found no indication of anyone ever setting the parameter, or
complaining about the default being wrong, after it was introduced
as a way to handle backwards-compatibility with linux prior to
c61eef726a78 ("drm: add support for monotonic vblank timestamps"),
so it's probably safer to just remove the parameter completely
and only allowing the default behavior.

<title>drm/syncobj: Add a signal ioctl (v3)</title>

This IOCTL provides a mechanism for userspace to trigger a sync object
directly.  There are other ways that userspace can trigger a syncobj
such as submitting a dummy batch somewhere or hanging on to a triggered
sync_file and doing an import.  This just provides an easy way to
manually trigger the sync object without weird hacks.

The motivation for this IOCTL is Vulkan fences.  Vulkan lets you create
a fence already in the signaled state so that you can wait on it
immediatly without stalling.  We could also handle this with a new
create flag to ask the driver to create a syncobj that is already
signaled but the IOCTL seemed a bit cleaner and more generic.

v2:
 - Take an array of sync objects (Dave Airlie)
v3:
 - Throw -EINVAL if pad != 0
