Bug Description
On a KVM node, this test in the ubuntu_
selftests: cpu-on-off-test.sh
======
pid 479's current affinity mask: 1
pid 479's new affinity mask: 1
CPU online/offline summary:
skip all tests:: since there is only one cpu: 0
not ok 1..1 selftests: cpu-on-off-test.sh [FAIL]
Maybe we should not mark this as failed if it's skipped.
