Chris Wilson 429732e860 drm/i915/breadcrumbs: Update bottom-half before marking as complete ... When adding a new request to the breadcrumb rbtree, we mark all those requests inside the rbtree that are already completed as complete. This wakes those waiters up and allows them to skip the spinlock before returning to userspace. If one of those is the current bottom-half and allocated its intel_wait on the stack, it may then overwrite the b->irq_wait upon exiting i915_wait_request() just as the interrupt handler dereferences it.
