rpcrdma: Merge svcrdma and xprtrdma modules into one Bi-directional RPC support means code in svcrdma.ko invokes a bit of code in xprtrdma.ko, and vice versa. To avoid loader/linker loops, merge the server and client side modules together into a single module. When backchannel capabilities are added, the combined module will register all needed transport capabilities so that Upper Layer consumers automatically have everything needed to create a bi-directional transport connection. Module aliases are added for backwards compatibility with user space, which still may expect svcrdma.ko or xprtrdma.ko to be present. This commit reverts commit 2e8c12e1b765 ("xprtrdma: add separate Kconfig options for NFSoRDMA client and server support") and provides a single CONFIG option for enabling the new module.

RPCRDMA: rpc rdma transport switch This implements the configuration and building of the core transport switch implementation of the rpcrdma transport. Stubs are provided for the rpcrdma protocol handling, and the infiniband/iwarp verbs interface. These are provided in following patches.

xprtrdma: Pre-allocate backward rpc_rqst and send/receive buffers xprtrdma's backward direction send and receive buffers are the same size as the forechannel's inline threshold, and must be pre- registered. The consumer has no control over which receive buffer the adapter chooses to catch an incoming backwards-direction call. Any receive buffer can be used for either a forward reply or a backward call. Thus both types of RPC message must all be the same size.
