You probably already know
the CE Workgroup Device Mainlining Project. Goes over some of the reasons why
mainline kernels don't run on phones. Adding Tim Bird to the thread.
He did a talk
at ELC back in March of this year about this effort and more information.

Very often phone vendors have to make decisions to get the product out
and they might not have the resources to upstream and ensure upstream
kernels continue to run on their devices.
