Subject: linux-next: build failure after merge of Linus' tree

Hi all,

With Linus' tree, today's linux-next build (powerpc allyesconfig) failed
like this:

drivers/infiniband/sw/built-in.o:(.opd+0x1698): multiple definition of `copy_data'
drivers/infiniband/hw/built-in.o:(.opd+0xe5f8): first defined here
drivers/infiniband/sw/built-in.o:(.opd+0x1320): multiple definition of `rxe_av_from_attr'
drivers/infiniband/hw/built-in.o:(.opd+0xe280): first defined here
drivers/infiniband/sw/built-in.o:(.opd+0x18d8): multiple definition of `rxe_do_task'
drivers/infiniband/hw/built-in.o:(.opd+0xe838): first defined here

and lots of others.

Caused by commit

  8700e3e7c485 ("Soft RoCE driver")
