Krishna Kumar	c9edea298e	RDMA/amso1100: Prevent deadlock in destroy QP ... It is possible to swap the CQs used for send_cq and recv_cq when creating two different QPs. If these two QPs are then destroyed at the same time, an AB-BA deadlock can occur because the CQ locks are taken our of order. Fix this by always taking CQ locks in a fixed order.

Tom Tucker	e52e6080ca	RDMA/amso1100: Add spinlocks to serialize ib_post_send/ib_post_recv ... The AMSO driver was not thread-safe in the post WR code and had code that would sleep if the WR post FIFO was full. Since these functions can be called on interrupt level I changed the sleep to a udelay.
