Subject: [PATCH 4.0 42/60] drm/amdkfd: allow unregister process with queues

4.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Oded Gabbay <oded.gabbay@...il.com>

commit 1e5ec956a057585adaa1365615c82810b2f5356f upstream.

Sometimes we might unregister process that have queues, because we couldn't
preempt the queues. Until now we blocked it with BUG_ON but instead just
print it as debug.
