Does this require a mass rebuild? I just wonder if there are packages
which check for the page size at configure time and embed it in the
code.

I'm going to get ahead here and say probably a mass rebuild *won't* be
required. I've been running a custom 4K page kernel on the Pine64
with a regular Fedora/aarch64 userspace -- and apart from qemu --
everything is working fine.

(I don't think the qemu problems have anything to do with page size.)
