4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michal Kalderon <Michal.Kalderon@xxxxxxxxxx>
[ Upstream commit 090477e4acb31c5dd674940c7c01d4f16bd1ac41 ]
A previous commit 4609adc27175 ("qede: Fix qedr link update")
added a flow that could allocate rdma event objects from an
interrupt path (link notification). Therefore the kzalloc call
should be done with GFP_ATOMIC.
