However, just disabling CONFIG_XZ_DEC on one of my defconfigs

Just disabling CONFIG_XZ_DEC is not enough as there's also
a MODULE_VERSION() in net/ipv4/tcp_cubic.c.
So you also have to disable CONFIG_TCP_CONG_CUBIC.

 __start___modver and __stop___modver are equal, so the __modver
section has no entries, but it's size is non-zero:

  4 __modver      000005a0  00185a60  00185a60  00185a60  2**0
                  ALLOC

BTW, so far it didn't crash on ARAnyM, but if there's memory corruption,
it still may go undetected depending on what is corrupted.
