[$] Running a mainline kernel on a cellphone
One of the biggest freedoms associated with with free software is the ability to
replace a program with an updated or modified version. Even so, of the
many millions of people using Linux-powered phones, few are able to
run a mainline kernel on those phones, even if they have the technical
skills to do the replacement. The sad fact is that no mainstream phone
available runs mainline kernels. A session at the 2015 Kernel Summit, led
by Rob Herring, explored this problem and what might be done to address it.
