rdma-core 13 fails to build on Ubuntu 16.04.1 LTS

[Amrani, Ram]

I failed to build rdma-core on Ubuntu 16.04.1 LTS.

Most errors looked like this: undefined reference to `udma_to_device_barrier'.

e.g.:
[115/175] Building C object providers/mlx4/CMakeFiles/mlx4-rdmav2.dir/qp.c.o
../providers/mlx4/qp.c: In function 'set_data_seg':
../providers/mlx4/qp.c:206:2: warning: implicit declaration of function 'udma_to_device_barrier' [-Wimplicit-function-declaration]
  udma_to_device_barrier();
  ^

  udma_to_device_barrier();
  ^

  udma_to_device_barrier(); /* Memory barrier to ensure data is written before valid bit is set */

rdma-core 14 works well, however.

Is this a known issue?

Thanks,
Ram

Yes, you need to cherry pick this patch for ARM:

commit 3f26e322622e93546f1b3a1a89c788adcebedcbe
Author: Jarod Wilson <jarod-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

    Fix udma_to_device_barrier on aarch64
    
    The definition for udma_to_device_barrier on aarch64 is missing. Looks
    like an oversight in the commit that removed the old barrier macros and
    added this one.
