x86: KVM guest: disable clock before rebooting.
This patch writes 0 (actually, what really matters is that the LSB is cleared) to the system time msr before shutting down the machine for kexec. Without it, we can have a random memory location being written when the guest comes back It overrides the functions shutdown, used in the path of kernel_kexec() (sys.c) and crash_shutdown, used in the path of crash_kexec() (kexec.c) Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
