Hmm, sounds to me an awful lot like the existing omap_bus_sync() ? However, you remove that feature when you remove omap_reserve() here becasue omap_reserve() ss not called from your new reserve function. Are you *really* sure you don't need the functions called there? This is a pretty big change that's not mentioned anywhere in the changelog.
