- Prevent stale CPU hotplug state in the cpu_down() path which was detected by stress testing the sysfs interface - Ensure that the target CPU hotplug state for the boot CPU is CPUHP_ONLINE instead of the compile time init value CPUHP_OFFLINE. - Switch back to the original behaviour of warning when a CPU hotplug callback in the DYING/STARTING section returns an error code. Otherwise a buggy callback can leave the CPUs in an non recoverable state. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmOUtQQTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoXGLD/4h+BkT+76oQ6MEmOQC/uaDzM2eOTlE vuq9iMTMCiHjiBmkzrGT2yxzpOYiEvDJVEHfCBrwskI2rAHrjtx2VCk5yoYPajoI P604Qgml+PTCk0uOxy2pPenF4PpTQ+oe3UdfZxc3zz+Qirzsd2QpXaiY6KrNktIN vnEY0mnQjsCKf5V1/Ckws0lMUMrgHFnxQhEyT8Bvo5BhTHMpsx3zS4l0QwBanqSo hqiiYIja9alRcOKSf2l1XZB6XoNOVcubRV1YZ8saN0RJ8P7gBkeR/6Sk0Imwsn2P k3xdW1AOCoCbG8NnXH7g+ohP8k5AlpP59SsMVujXwTqI55NURFibv0rj5ZhQhSWa MKstICvUc6xyqHHwtriHyzqy3naKkiptEuxto9WL6WZYF+Xj/3JD0tT4pRvey18/ yxOjDqZAYHmS3cOh7m6VzOG4CwAu9p5qloZVzvqgR0G3LzMu66e7mucciG26TFPb C5mmUsb8SvW0yYr8ZOtKXwoQKMTZtAmU9L7DJEKRZ8AesKswaAASTgb+lDFXRId6 lxI2Vs8DPQXYJMtioYEKnwzmgHaPJ6VQKv7++74xZMHMpR/Mc3+Sm4iSIXkJK87o 07DwJMTUPR3E5/K6d4ERSvlLaKVNk3frsylhgsSmPbJn672jBe8HlDSU2uLsso2O 9kTe9KPikuHWEw== =7mN4 -----END PGP SIGNATURE----- Merge tag 'smp-core-2022-12-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull CPU hotplug updates from Thomas Gleixner: "A small set of updates for CPU hotplug: - Prevent stale CPU hotplug state in the cpu_down() path which was detected by stress testing the sysfs interface - Ensure that the target CPU hotplug state for the boot CPU is CPUHP_ONLINE instead of the compile time init value CPUHP_OFFLINE. - Switch back to the original behaviour of warning when a CPU hotplug callback in the DYING/STARTING section returns an error code.
