Ah crap, I forgot all about the scheduler mess. Sorry about that, I've been focusing on device-specific stuff too much (nothing I much care lives outside of drivers/...)
So you are right, for some types of devices, the andoid-common tree isn't the best idea. However, the validation "costs" better be starting all over based on the intrusiveness of these patches, they are non-trivial :(
