From 7bbc124e7e8fb544288ccd1f5185643a7d0554b8 Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Thu, 20 Oct 2016 13:26:04 +0200 Subject: [PATCH] exec: call cpu_exec_exit() from a CPU unrealize common function As cpu_exec_exit() mirrors the cpu_exec_realizefn(), rename it as cpu_exec_unrealizefn(). Create and register a cpu_common_unrealizefn() function for the CPU device class and call cpu_exec_unrealizefn() from this function. Remove cpu_exec_exit() from cpu_common_finalize() (which mirrors init, not realize), and as x86_cpu_unrealizefn() and ppc_cpu_unrealizefn() overwrite the device class unrealize function, add a call to a parent_unrealize pointer.
