True, but I don't see any way around it given that someone could
hotplug 50 HCAs after the SDP module is loaded.  Also it's possible to
implement FMRs to use vmalloc space more efficiently than the original
VAPI code did, so I don't think this should be a problem in practice
(the 1024 FMRs SDP wants should only take about 128 KB of vmalloc
space).  And any non-obsolete architecture has unlimited vmalloc space...
