50e1092b3a SUNRPC xprtrdma: fix XDR tail buf marshalling for all ops
rpcrdma_convert_iovs is passed an xdr_buf representing either an RPC
request or an RPC reply. In the case of a request, several
calculations and tests involving pos are unnecessary. In the case of a
reply, several calculations and tests involving pos are incorrect (the
code tests pos against the reply xdr buf's len field, which is always
0 at the time rpcrdma_convert_iovs is executed). This change removes
the incorrect/unnecessary calculations and tests involving pos.

This fixes an observed problem when reading certain file sizes over
NFS/RDMA.

cfcb43ff7c SUNRPC: remove NFS/RDMA client's binary sysctls
Support for binary sysctls is being deprecated in 2.6.24. Since there
are no applications using the NFS/RDMA client's binary sysctls, it
makes sense to remove them. The patch below does this while leaving
the /proc/sys interface unchanged.

Please consider this for 2.6.24.

net/sunrpc/xprtrdma/rpc_rdma.c:222: warning: format '%llx' expects type 'long long unsigned int', but argument 4 has type 'u64'

Noticed on PowerPC pseries_defconfig build.
