For example, we don't enable kdump by default on fedora. Often people don't like 128MB of their laptop memory not being used. And I have been thinking how to reduce memory usage further so that I can enable kdump by default on Fedora. Instead, now this 72MB increase come in picture which does not bring us any benefit for most of the people. Only people who benefit from it are large memory servers and everybody else (having memory more than 4G) pays this penalty. I rather prefer that this penalty of 72M is paid only by those who need to have memory reservation above 4G.
