Comment 3 for bug 1980861

I'm hoping to look into the effects of MULTI_PERCPU on the smaller Pi platforms (in particular the Pi Zero 2 and 3A+ which each have 512MB of RAM and, with the arm64 arch, typically have ~250MB free at runtime). Unfortunately building a local version of the linux-raspi package (just naively with sbuild) has thus far defeated me, but if I can get a version with the relevant config I'll run through some tests.
