While in general it's nice to see kernel memory consumption decrease, it's disturbing to see it happen between an -rc6 and -rc7 release.
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.
