[PATCH v5 0/2] cpuhp: fix some st->target issues
From: Phil Auld
Date: Thu Nov 17 2022 - 11:27:47 EST
Fix a few cpuhp related issues.
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.
v3: Added code to make sure st->target == target in the nop case.
v4: Use WARN_ON in the case where state == target but st->target does
not.
v5: Fixed lowercase on first patch title and cleaned up cover letter.
Rebased on v6.1-rc5.

cpuhp: Make target_store() a nop when target == state
cpuhp: Set cpuhp target for boot cpu
