The following commit has been merged into the smp/core branch of tip: Commit-ID: fe22944cf05ede8e6f841cfecdb7093a53a3d9b3 Gitweb: https://git.kernel.org/tip/fe22944cf05ede8e6f841cfecdb7093a53a3d9b3 Author: xiaoming Wang <xiaoming.wang@intel.com> AuthorDate: Tue, 19 Dec 2023 11:34:11 +08:00 Committer: Thomas Gleixner <tglx@linutronix.de> CommitterDate: Wed, 20 Dec 2023 16:25:15 +01:00 cpu/hotplug: Increase the number of dynamic states The dynamically allocatable hotplug state space can be exhausted by the existing drivers and infrastructure which install CPU hotplug states dynamically. That prevents new drivers and infrastructure from installing dynamically allocated states. Increase the size of the CPUHP_AP_ONLINE_DYN state by 10 to make room.
