The goal is to split the functions such that cpu-exec is CPU specific content, while cpus-exec-common.c is generic code only. The function interface to cpu-exec needs to be virtualised to prepare support for multi-arch and moving these definitions out saves bloating the QOM interface. So move these definitions out of cpu-exec to a new module, cpu-exec-common. Backports commit 5abf9495ca9ff41160260ac274115825c10545cc from qemu
