Dave Young a58130ddc8 cpu-hotplug selftests: print failure status instead of cause make error 
Original behavior:
  bash-4.1$ make -C cpu-hotplug run_tests
  make: Entering directory `/home/dave/git/linux-2.6/tools/testing/selftests/cpu-hotplug'
  ./on-off-test.sh
  make: execvp: ./on-off-test.sh: Permission denied
  make: *** [run_tests] Error 127
  make: Leaving directory `/home/dave/git/linux-2.6/tools/testing/selftests/cpu-hotplug'

After applying the patch:
  bash-4.1$ make -C cpu-hotplug run_tests
  make: Entering directory `/home/dave/git/linux-2.6/tools/testing/selftests/cpu-hotplug'
  /bin/sh: ./on-off-test.sh: Permission denied
  cpu-hotplug selftests: [FAIL]
  make: Leaving directory `/home/dave/git/linux-2.6/tools/testing/selftests/cpu-hotplug'

Akinobu Mita d89dffa976 fault-injection: add selftests for cpu and memory hotplug 
This adds two selftests

* tools/testing/selftests/cpu-hotplug/on-off-test.sh is testing script
for CPU hotplug

1. Online all hot-pluggable CPUs
2. Offline all hot-pluggable CPUs
3. Online all hot-pluggable CPUs again
4. Exit if cpu-notifier-error-inject.ko is not available
5. Offline all hot-pluggable CPUs in preparation for testing
6. Test CPU hot-add error handling by injecting notifier errors
7. Online all hot-pluggable CPUs in preparation for testing
8. Test CPU hot-remove error handling by injecting notifier errors

* tools/testing/selftests/memory-hotplug/on-off-test.sh is doing the
similar thing for memory hotplug.

1. Online all hot-pluggable memory
2. Offline 10% of hot-pluggable memory
3. Online all hot-pluggable memory again
4. Exit if memory-notifier-error-inject.ko is not available
5. Offline 10% of hot-pluggable memory in preparation for testing
6. Test memory hot-add error handling by injecting notifier errors
7. Online all hot-pluggable memory in preparation for testing
8. Test memory hot-remove error handling by injecting notifier errors
