H A Dmthca_main.c1d1f19cf Sat Feb 10 15:17:26 CST 2007 Michael S. Tsirkin <mst@mellanox.co.il> IB/mthca: Give reserved MTTs a separate cache line

MTTs are allocated in non-cache-coherent memory, so we must give
reserved MTTs their own cache line, to prevent both device and
CPU from writing into the same cache line at the same time.
