Most of this went away when I disabled SLUB debugging and other
kernel hacking options.  The wifi cfg80211_inform_bss_frame
remains, however.  I'll go dig some more on that tomorrow...didn't
see anything obvious at first glance.

But, perhaps there could be some improvements to
kmemleak to make it deal better with the various kernel
debugging features?

Thanks,
Ben
