Refactor cursor buffer setting such that the code to actually update the
cursor lives in a new function, intel_crtc_cursor_set_obj(), and takes
a GEM object as a parameter. The existing legacy cursor ioctl handler,
intel_crtc_cursor_set() will now perform the userspace handle lookup and
then call this new function.
This refactoring is in preparation for the universal plane cursor
support where we'll want to update the cursor with an actual GEM buffer
object (obtained via drm_framebuffer) rather than a userspace handle.

If drivers support universal planes and have registered a cursor plane
with the DRM core, we should use that universal plane support when
handling legacy cursor ioctls. Drivers that transition to universal
planes won't have to maintain separate legacy ioctl handling; drivers
that don't transition to universal planes will continue to operate
without any change to behavior.
Note that there's a bit of a mismatch between the legacy cursor ioctls
and the universal plane API's --- legacy ioctl's use driver buffer
handles directly whereas the universal plane API takes drm_framebuffers.
Since there's no way to recover the driver handle from a
drm_framebuffer, we can implement legacy ioctl's in terms of universal
plane interfaces, but cannot implement universal plane interfaces in
terms of legacy ioctls. Specifically, there's no way to create a
general cursor helper in the way we previously created a primary plane
helper.
It's important to land this patch before any patches that add universal
cursor support to individual drivers so that drivers don't have to worry
about juggling two different styles of reference counting for cursor
buffers when userspace mixes and matches legacy and universal cursor
calls. With this patch, a driver that switches to universal cursor
support may assume that all cursor buffers are wrapped in a
drm_framebuffer and can rely on framebuffer reference counting for all
cursor operations.
v4:
- Add comments pointing out setplane_internal's reference-eating
semantics.
v3:
- Drop drm_mode_rmfb() call that is no longer needed now that we're
using setplane_internal(), which takes care of deref'ing the
appropriate framebuffer.
v2:
- Use new add_framebuffer_internal() function to create framebuffer
rather than trying to call directly into the ioctl interface and
look up the handle returned.
- Use new setplane_internal() function to update the cursor plane
rather than calling through the ioctl interface. Note that since
we're no longer looking up an fb_id, no extra reference will be
taken here.
- Grab extra reference to fb under lock in !BO case to avoid issues
where racing userspace could cause the fb to be destroyed out from
under us after we grab the fb pointer.

Refactor DRM setplane code into a new setplane_internal() function that

ioctls on top of the universal plane interface.
v3:
- Move integer overflow checking from setplane_internal to setplane
ioctl. The upcoming legacy cursor support via universal planes needs
to maintain current cursor ioctl semantics and not return error for
these extreme values (found via intel-gpu-tools kms_cursor_crc test).

A deadlock occurs when PDU containing invalid SMP opcode is received on
Security Manager Channel over LE link and conn->pending_rx_work worker
has not run yet.
When LE link is created l2cap_conn_ready() is called and before
returning it schedules conn->pending_rx_work worker to hdev->workqueue.
Incoming data to SMP fixed channel is handled by l2cap_recv_frame()
which calls smp_sig_channel() to handle the SMP PDU. If
smp_sig_channel() indicates failure l2cap_conn_del() is called to delete
the connection. When deleting the connection, l2cap_conn_del() purges
the pending_rx queue and calls flush_work() to wait for the
pending_rx_work worker to complete.
Since incoming data is handled by a worker running from the same
workqueue as the pending_rx_work is being scheduled on, we will deadlock
on waiting for pending_rx_work to complete.

The conn->link_key variable tracks the type of link key in use. It is
set whenever we respond to a link key request as well as when we get a
link key notification event.
These two events do not however always guarantee that encryption is
enabled: getting a link key request and responding to it may only mean
that the remote side has requested authentication but not encryption. On
the other hand, the encrypt change event is a certain guarantee that
encryption is enabled. The real encryption state is already tracked in
the conn->link_mode variable through the HCI_LM_ENCRYPT bit.
This patch fixes a check for encryption in the hci_conn_auth function to
