[PATCH v5 1/2] arm64: kvm: allows kvm cpu hotplug

2015-05-28 Thread AKASHI Takahiro
The current kvm implementation on arm64 does cpu-specific initialization at system boot, and has no way to gracefully shutdown a core in terms of kvm. This prevents, especially, kexec from rebooting the system on a boot core in EL2. This patch adds a cpu tear-down function and also puts an existin
