[ewg] OFED-3.5.2-daily does not work properly on latest RHEL6.4 kernel.

Dear members.

OFED-3.5.2-daily does not work properly on latest RHEL6.4 kernel.

I get the following error when I execute 'service openibd start' on
Scientific Linux 6.4 (kernel: 2.6.32-358.14.1.el6.x86_64)

    compat: exports duplicate symbol __pskb_copy (owned by kernel)
    compat: exports duplicate symbol __pskb_copy (owned by kernel)
    compat: exports duplicate symbol __pskb_copy (owned by kernel)

    compat: exports duplicate symbol __pskb_copy (owned by kernel)


I found about an article and a patch for this problem.
  http://community.mellanox.com/thread/1228
  http://community.mellanox.com/servlet/JiveServlet/download/2333-1858/mlnx-ofed-pskb-copy.diff.zip

This is a patch for Mellanox OFED.2.0,
but this is also useful for OFED-3.5.2

This is because "tcp: take care of misalignments" patch use
__pskb_copy funciton.

  This patch was applyed on 2.6.32-358.10.1.el6

[2.6.32-358.10.1.el6]
    ...
    - [net] tcp: take care of misalignments (Thomas Graf) [954298 896233]

By the way, Does anyone point me how to make rpm package for compat-rdma?
Or how to compile compat-ofed from git source.

I'll make a patch for this problem.

Sincerely.
