The dependency tracking done in the arm-soc tree performed by Arnd and 
Olof is merely a way for you to _base_ your branch on top of other 
people's branch before they pull it from you.  For example, you may 
decide to build your branch on top of Greg's to get some prerequisite 
commits for your work. In that case the goal for the arm-soc maintainers 
is to avoid the situation where a pull of the arm-soc tree into mainline 
would also pull greg's stuff without his asking for it.
