Well, not quite.  We have a number of platform-specific drivers for one
example.

Also, In fact I think it would benefit everyone if Android users could run
mainline kernels without major modifications on their systems.

Also, I think it would benefit everyone if Android drivers were merged into
the mainline.

Moreover, I think this stuff may actually be useful to someone beyond Android,
because it's proven working and people can readily play with it.  Which is not
going to happen if it's not in the mainline.

And I don't believe a user space power manager is going to be implemented
in a platform-idependent way, if at all (assuming we reject the Android
patches).
