4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Noa Osherovich <noaos@xxxxxxxxxxxx>
commit d76d2fe05fd93673d184af77255bbbc63780f4ea upstream.
Change Mellanox's broken_intx_masking() quirk from an "all Mellanox
devices" to a quirk for listed devices only.
[bhelgaas: remove #defines, reorder to keep other quirks together]
