Thanks. Since these are causing build issues, and it isn't entirely clear what's the right approach for now, I have dropped the changes from my branch to avoid any further issues. You don't need to resend these, lets finalize a solution and then I can apply them again.

I applied them here earlier. git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git opp/linux-next
