Subject: [PATCH 0/7] notifier error injection

This provides the ability to inject artifical errors to the following
notifier chain callbacks. It is useful to test the error handling of
notifier call chain failures.

 * CPU notifier
 * PM notifier
 * memory hotplug notifier
 * powerpc pSeries reconfig notifier

We already have cpu-notifier-error-inject.ko module providing such
functionality for the CPU notifier.  However, this patch set adds
common basic functions and consistent debugfs interface for them.

Akinobu Mita (7):
  pm: improve error code of pm_notifier_call_chain()
  debugfs: add debugfs_create_int
  fault-injection: notifier error injection
  cpu: CPU notifier error injection
  PM: PM notifier error injection
  memory: memory notifier error injection
  powerpc: pSeries reconfig notifier error injection
