Follow up on HZ=1000 for Chrome OS kernel v4.4

Project Member Reported by briannorris@chromium.org, Apr 18 2016

Issue description

On previous kernel versions, we've kept the x86 config defaulting to HZ=1000, while ARM and ARM64 have been stuck on HZ=100, with several platform configs bumping this up to HZ=250 or HZ=1000. For kernel 4.4, we are going to switch everything to HZ=1000, as we couldn't identify a reason for keeping the low-HZ, and higher HZ can help with interactivity, for instance.

This bug is opened to track any efforts to measure any power concerns related to this change.

We shipped all devices on 4.4 with HZ and power numbers were deemed acceptable. I do not think there is anything to do on this bug.

I meant "HZ=1000" in the comment above.
