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.

Userspace InfiniBand Management Datagram (MAD) support. This

is the kernel side of the userspace MAD support, which allows

userspace processes to send and receive MADs. You will also

Userspace InfiniBand access support. This enables the
|
|
kernel side of userspace verbs and the userspace
|
|
communication manager (CM). This allows userspace processes
|
|
to set up connections and directly access InfiniBand
|
|
hardware for fast-path operations. You will also need
|

libibverbs, libibcm and a hardware driver library from
|

<http://www.openfabrics.org/git/>.

These commands are parsed via per-device parsing tree and
