drivers/infiniband: Remove now-redundant smp_read_barrier_depends()
The smp_read_barrier_depends() does nothing at all except on DEC Alpha, and no current DEC Alpha systems use Infiniband: lkml.kernel.org/r/20171023085921.jwbntptn6ictbnvj@tower This commit therefore makes Infiniband depend on !ALPHA and removes the now-ineffective invocations of smp_read_barrier_depends() from the InfiniBand driver. Please note that this patch should not be construed as my saying that InfiniBand's memory ordering is correct, but rather that this patch does not in any way affect InfiniBand's correctness. In other words, the result of applying this patch is bug-for-bug compatible with the original. Signed-off-by: Paul E.
