I'm going to disable kernel_afdo on daisy because of this:
https://bugs.chromium.org/p/chromium/issues/detail?id=772450

We are pretty unlucky because we just disabled it two weeks ago and re-enabled it on Oct. 4. My guess is that compiler inlined slightly more aggressively due to the new profiles.

Unfortunately, it seems that we don't have other armv7 boards other than 3.8 or 3.10 or rk3288.
