Well done! Looks indeed like a suspect for the behavior you're seeing.
I suppose you will follow up with the mm people?

Yay, great news. I'm currently building a native GHC package for Debian/m68k
on Aranym and [kswapd] is taking around half of the CPU load. The suggestion
with drop_caches doesn't help all the time, unfortunately, so I'm really
looking forward getting this fixed :).

I expect the bad commit can just be reverted, as the surrounding code hasn't
changed?

Gr{oetje,eeting}s,

when I'm talking to journalists I just say "programmer" or something like that.
