From: Lihao Liang <lianglihao@huawei.com>
This commit adds support of the qemu command qemu-system-aarch64
to rcutorture.
Signed-off-by: Lihao Liang <lianglihao@huawei.com>
---
Comparing to the previous version, this patch lifts the limitation of
maximum 8 CPUs of option "-M virt" by adding "gic-version=host" to it.
This allows qemu to use the maximum CPU number supported by the actual
hardware.
This commit is against RCU's git branch rcu/dev
commit 505b61b2ec1d ("EXP: rcu: Add debugging info to other assertion")

This is to replace your previous patch, not to apply on top of it,
correct? (Either way is fine, just please let me know.)
Thanx, Paul
