[Intel-gfx] [PATCH 1/2] drm/i915/gem: Correct the locking and pin pattern for dma-buf

[Michael J. Ruhl]

From: Thomas Hellström <thomas.hellstrom@linux.intel.com>

If our exported dma-bufs are imported by another instance of our driver,
that instance will typically have the imported dma-bufs locked during
dma_buf_map_attachment(). But the exporter also locks the same reservation
object in the map_dma_buf() callback, which leads to recursive locking.

So taking the lock inside _pin_pages_unlocked() is incorrect.

Additionally, the current pinning code path is contrary to the defined
way that pinning should occur.

Remove the explicit pin/unpin from the map/umap functions and move them
to the attach/detach allowing correct locking to occur, and to match
the static dma-buf drm_prime pattern.

Add a live selftest to exercise both dynamic and non-dynamic
exports.

v2:
- Extend the selftest with a fake dynamic importer.
- Provide real pin and unpin callbacks to not abuse the interface.
v3: (ruhl)
- Remove the dynamic export support and move the pinning into the
  attach/detach path.
