P-state software coordination for ACPI core http://bugzilla.kernel.org/show_bug.cgi?id=5737Many non-ACPI systems are filling this field by mistake, which makes its usage confusing. Lets clean it.

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 ?
