[Qemu-devel] [RFC PATCH v2 2/9] exec: Do vmstate unregistration from cpu


From: Bharata B Rao
Subject: [Qemu-devel] [RFC PATCH v2 2/9] exec: Do vmstate unregistration from cpu_exec_exit()
Date: Fri, 11 Mar 2016 10:24:31 +0530

cpu_exec_init() does vmstate_register for the CPU device. This needs to be
undone from cpu_exec_exit(). This change is needed to support CPU hot
removal.
