Yeah, that's definitely an issue. Some of the ppc boxes in our internal test
setup have "only" 1G of RAM, and when the system is under load[*], you can
run out of free pages and start oom-killing stuff pretty quick w/64k pages...

I think you're both slightly confused. This is for switching the
_builders_ back to a 4KiB page kernel. Not Fedora, which is already
4KiB pages.
