Just one very high-level question: as this code is clearly derived from
the x86 version and nontrivial, could we move most of it out of
arch/{x86,arm64} into mm/kasan/init.c and have the rest in some header
file?

I think most of this could be moved out from arch code, but not everything.
E.g. kasan_init() function is too arch-specific.
