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. Phil Auld (2): cpuhp: Make target_store() a nop when target == state cpuhp: Set cpuhp target for boot cpu cpu.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) -- 2.31.1
