'struct irq_affinity_notify' and the related functions are only defined
when SMP enabled, so at present, mlx4 has to only run under SMP.
The related error (allmodconfig under unicore32):

Making the entire driver depend upon SMP is not the answer,
other Mellanox developers said that a proper fix is pending
so please be patient.

OK, thank you for your information. I shall bypass it, and continue.
