From: Lihao Liang <liangli...@huawei.com>
This commit adds support of the qemu command qemu-system-aarch64
to rcutorture. Use the following command to run:
./kvm.sh --qemu-cmd qemu-system-aarch64
Signed-off-by: Lihao Liang <liangli...@huawei.com>
---
The max CPUs supported by qemu machine 'virt' is 8 so the value of
CONFIG_NR_CPUS in some test configuration files needs to be adjusted.
