We allocate a small tracking structure as part of mlx4_ib_resize_cq(). However, we don't need to use GFP_ATOMIC -- immediately after the allocation, we call mlx4_cq_resize(), which allocates a command mailbox with GFP_KERNEL and then sleeps on a firmware command, so we better not be in an atomic context. This actually has a real impact, because when this GFP_ATOMIC allocation fails (and GFP_ATOMIC does fail in practice) then a userspace consumer resizing a CQ will get a spurious failure that we can easily avoid.
