I haven't looked at the cpufreq code recently but remember that it was needed to ensure that all the CPU which share clock/voltage gets updated (affected cpus) on freq change. The CPUs which needs SW co-ordination, should have this flag enabled and OMAP was falling in that category. May be I miss-understood its use, but can you confirm that SW co-ordination logic continues to work without this flag ?
