This series of patches implement memory windows for the rdma_rxe
driver. This is a shorter reimplementation of an earlier patch set.
They apply to and depend on the current for-next linux rdma tree.

v7:
Fixed a duplicate INIT_RDMA_OBJ_SIZE(ib_mw, ...) in rxe_verbs.c.
With this patch series, there are about 17 errors and 1 failure in rdma-core.
Zhu,
You have to sync the kernel-header file with the kernel.

After these patches, not sure if rxe can communicate with the physical
NICs correctly because of the
above errors and failure.
