drm/omap: EBUSY status handling in omap_gem_fault()
Subsequent threads returning EBUSY from vm_insert_pfn() was not
handled correctly. As a result concurrent access from new threads
to mmapped data caused SIGBUS.
See e79e0fe380847493266fba557217e2773c61bd1b ("drm/i915: EBUSY status
handling added to i915_gem_fault()").
