Looked into this further.  It turns out that the Kconfigs for this test 
run were generated from an older kernel version, so the Kconfigs don't 
match what's in v3.19-rc7.  I've added an additional verification check 
that should catch this if it happens again, and will post a corrected 
test run shortly.
