Your call.

Note that removing code from mainline won't help users obtain older, 
smaller, -stable kernel releases, free from the bug we were discussing. 
(The bug appeared in Linux v2.6.32.)

BTW, if you did want to boot Linux on a 16 MB system, you do have some 
options.

Contributing to this kind of effort probably has value for IoT 
deployments. I suspect it also cuts a small amount of bloat from a large 
number of other Linux systems.
