Anyone know what's going on?

Comment 1 by achuith@chromium.org, Feb 7 2018 

Is it because of this CL:
https://chromium-review.googlesource.com/c/chromiumos/chromite/+/887545

Should we drop the ',check'?

Comment 2 by ihf@chromium.org, Feb 7 2018 

We are trying to standardize the backend. The warnings are important. What do you get when you run

grep -E "model|flags" /proc/cpuinfo | sort | uniq
