Does this build for Arm, seeing that there's no hap_enabled()
definition there? Or have I missed its addition earlier in this
series?

It moved to common code sched.h in an earlier patch.

I went through the series and didn't find where hap_enabled() is defined for Arm in this series. Do you mind pointing the exact patch?

Cheers,
