To ease development and maintenance of the siw kernel module

source code, it has been splitted into two independent directories

softiwarp/ and softiwarp_old/. both directories keep all files

needed to build a siw kernel module. 

softiwarp/

contains the code aligned to the current linux kernel development

tree. it does not contain any legacy code to run with older kernels.

this code is updated frequently, but runs only on newer kernels.

it has been tested for kernels back to kernel version 2.6.36.2.

code documentation (IMPLEMENTATION.txt) will be updated within

the next days.

softiwarp_old/

contains code which compiles and runs on older kernels, but may

soon break on newer kernels. code maintenance is sloppy and

it is recommended to use the newer softiwarp/ code base if 

possible.

softiwarp_old/ has been removed.

With kernel version 3.15 the OFA core changed the way it maintains

registered user communication buffers. The new code would result

in inefficient initialization of RDMA data source or sink location for

a software RDMA stack. Therefore, siw abandons using OFA core

user page management (ib_umem_get() etc.) and implememnts its

own simple, but better suited management of pinned user pages.
