[PATCH v3 0/2] cpuhp: fix some st->target issues

[Phil Auld]

Several small fixes that clean up some cpuhp inconsistencies.
The first prevents target_store() from calling cpu_down() when
target == state which prevents the cpu being incorrectly marked
as dying.  The second just makes the boot cpu have a valid cpuhp
target rather than 0 (CPU_OFFLINE) while being in state
CPU_ONLINE.

A further issue which these two patches don't address is that
the cpuX/online file looks at the device->offline state and can
thus get out of sync with the actual cpuhp state if the cpuhp
target is used to change state.

v3: Added code to make sure st->target == target in the nop case.

Phil Auld (2):
  cpuhp: make target_store() a nop when target == state
  cpuhp: Set cpuhp target for boot cpu
