[PATCH v2 0/3] cpu/hotplug: rollback and "fail" interface fixes

[vincent . donnefort]

From: Vincent Donnefort <vincent.donnefort@xxxxxxx>

This patch-set intends to unify steps call throughout hotplug and
hotunplug.

It also improves the "fail" interface, which can now be reset and will
reject states for which a failure can't be recovered.

v2:
  - Reject all DEAD steps in the fail interface.
  - Do not try to recover from a DEAD step failure.
  - WARN on DEAD step failure.
  - Additional comment in cpuhp_reset_state().
  - Fix WARN_ON coding style issues.

Vincent Donnefort (3):
  cpu/hotplug: Allowing to reset fail injection
  cpu/hotplug: CPUHP_BRINGUP_CPU failure exception
  cpu/hotplug: Add cpuhp_invoke_callback_range()
