Currently, the kernel boot parameters specified by the kvm.sh --bootargs parameter are placed near the beginning of the -append list that is passed to qemu. This means that in the not-uncommon case of a kernel boot parameter where the last argument wins, the --bootargs list overrides neither the list in the .boot file nor the additional parameters supplied by the rcutorture scripting. This commit therefore places the kernel boot parameters specified by the kvm.sh --bootargs parameter at the end of qemu's -append list. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
