Our legacy SetPlane updates perform integer overflow checking on a
plane's destination rectangle in drm_mode_setplane(), and atomic updates
handled as part of a drm_atomic_state transaction do the same checking
in drm_atomic_plane_check(). However legacy cursor updates that get
routed through universal plane interfaces may bypass this overflow
checking if the driver's .update_plane is serviced by the transitional
plane helpers rather than the full atomic plane helpers.
Move the check for destination rectangle integer overflow from the
drm_mode_setplane() to __setplane_internal() so that it also covers
cursor operations.
This fixes an issue first noticed with i915 commit:
commit ff42e093e9
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Mon Mar 2 16:35:20 2015 +0100
Revert "drm/i915: Switch planes from transitional helpers to full
atomic helpers"
The above revert switched us from full atomic helpers back to the
transitional helpers, and in doing so we lost the overflow checking here
for universal cursor updates. Even though such extreme cursor positions
are unlikely to actually happen in the wild, we still don't want there
to be a change of behavior when drivers switch from transitional helpers
to full helpers.
v2: Move check from setplane ioctl to setplane_internal rather than
adding an additional copy of the checks to the transitional plane
helpers. (Daniel)

Users of the atomic state assume that if the pointer to a crtc, plane or
connector is not NULL in the respective object vector, than the state
for that object in *_states vector also won't be NULL. That assumption
was broken by drm_atomic_state_clear(), which would clear the state
pointer but leave the pointer to the object still set.
This fixes a NULL pointer dereference in i915 caused by the use of
drm_atomic_state_clear().

- Some GPIO fixes for OMAP platforms added a few lines. This was also fixes for

The UART reference clock speed is 7273.8 kHz, not 72738 kHz.
Dots aren't usually used in node names even though ePAPR permits

This patch changes the name to refclk7273800hz, reflecting the

Now that cmd_drv is gone the handling for core and driver ioctls is
mostly identical, so eliminate the duplication. Also take the
opportunity to simplify the range checks to be less cluttered.

ioctl->cmd_drv is pointless and we can just as well stick the full ioctl
definition into ioctl->cmd.

Currently DRM_IOCTL_DEF_DRV does '[DRM_IOCTL_NR(DRM_##ioctl)]' which
doesn't make much sense since DRM_##ioctl is already a the raw ioctl
number. So change it to 'DRM_IOCTL_NR(DRM_IOCTL_##ioctl) - DRM_COMMAND_BASE'
which means the DRM_IOCTL_NR() now makes sense, and also this also means
if there's a mistake in the DRM_IOCTL_##ioctl macros we might get a
warning about it (eg. we would have gotten a sparse warning about the
i915 colorkey get/set ioctl being defined to be the same thing).
