+- Reject receive work requests if QP is in RESET state
+- In case of lost interrupts, trigger EOI to reenable interrupts
+- Filter PATH_MIG events if QP was never armed
+- Release mutex in error path of alloc_small_queue_page()
+- Check idr_find() return value

+- Don't allow creating UC QP with SRQ
+- Fix reported max number of QPs and CQs in systems with >1 adapter
+- Reject dynamic memory add/remove when ehca adapter is present
+- Remove reference to special QP in case of port activation failure
