Subject: [PATCH rdma-next v1 1/5] RDMA: Clean structures from CONFIG_INFINIBAND_ON_DEMAND_PAGING

From: Leon Romanovsky <leonro@...lanox.com>

CONFIG_INFINIBAND_ON_DEMAND_PAGING is used in general structures
to micro-optimize the memory footprint. Remove it, so it will allow
us to simplify various ODP device flows.
