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.
