I have consolidated them, so we would support more features in the flag
automatically when there will be a need.

In Android kernel we don't have unfortunately the debugfs compiled-in,
so this information is still only for kernel testing with some Linux
distro.

I have been thinking to switch into sysfs interface, so we could
have it in Android as well. This patch change adding a generic 'flags'
which would be more 'stable' (which is a requirement for sysfs contract)
is also a closer step into that direction. But that is for longer
discussion and not for this $subject.
