This commit causes the kvm-test-1-run-qemu.sh script to check the TORTURE_AFFINITY environment variable and to add "taskset" commands to the qemu-cmd file. The first "taskset" command is applied only if the TORTURE_AFFINITY environment variable is a non-empty string, and this command pins the current scenario's guest OS to the specified CPUs. The second "taskset" command reports the guest OS's affinity in a new "qemu-affinity" file. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
