Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
---Steps to Reproduce---
When passed a negative number to 'maxcpus' parameter, Qemu aborts
with a core dump.
Run the following command with maxcpus argument as negative number
ppc64-softmmu/qemu-system-ppc64 --nographic -vga none -machine
pseries,accel=kvm,kvm-type=HV -m size=200g -device virtio-blk-pci,
drive=rootdisk -drive file=/home/images/pegas-1.0-ppc64le.qcow2,
if=none,cache=none,id=rootdisk,format=qcow2 -monitor telnet
:127.0.0.1:1234,server,nowait -net nic,model=virtio -net
user -redir tcp:2000::22 -device nec-usb-xhci -smp 8,cores=1,
threads=1,maxcpus=-12
