I checked on x86_64 and ppc64 (they both have KASAN implementation):
I added the following:
printk("%s: %d\n", __func__, virt_addr_valid(0));
in x86_64: sounds/last.c in pp64: arch/powerpc/kernel/setup-common.c
and in both the cases the output is 0 (false) when the same in arm64 is 1 (true). Therefore I think we should proceed with the change.
