CM has no use for RMPP or really any of the GSI functions.  I haven't
seen anyone doing PM from the kernel.  Right now DM is in the kernel
(for Topspin's stack too) but I would like to try to move that to
userspace.  I assume your vendor-specific SM sync is in userspace as
well.  Given that most of the users are in userspace, I would like to
try and move the general code to a user library too.
