What you _really_ want to do is avoid large mallocs after boot, or use

Is there a position available working on mmu CPU? Joking, :)
Yes, some problems are serious on nommu linux. But I think we should
try to fix them not avoid them.
Exactly, and the *real* fix is to modify userspace not to make > PAGE_SIZE
mallocs[*] if it is to be nommu friendly. It is the kernel hacks to do things
like limit cache size that are the bandaids.
Of course, being an embedded system, if they work for you then that's
really fine and you can obviously ship with them. But they don't need to
go upstream.
