Message-ID: <162860067530.395.3453742829000031569.tip-bot2@tip-bot2> Date: Tue, 10 Aug 2021 13:04:35 -0000 From: "tip-bot2 for Sebastian Andrzej Siewior" <tip-bot2@...utronix.de> To: linux-tip-commits@...r.kernel.org Cc: Sebastian Andrzej Siewior <bigeasy@...utronix.de>, Thomas Gleixner <tglx@...utronix.de>, x86@...nel.org, linux-kernel@...r.kernel.org Subject: [tip: perf/core] perf/x86/intel: Replace deprecated CPU-hotplug functions. The following commit has been merged into the perf/core branch of tip: Commit-ID: 4db0d3d3eeb8e15fce529480e4e99a3776f69604 Gitweb: https://git.kernel.org/tip/4db0d3d3eeb8e15fce529480e4e99a3776f69604 Author: Sebastian Andrzej Siewior <bigeasy@...utronix.de> AuthorDate: Tue, 03 Aug 2021 16:15:53 +02:00 Committer: Thomas Gleixner <tglx@...utronix.de> CommitterDate: Tue, 10 Aug 2021 15:00:26 +02:00 perf/x86/intel: Replace deprecated CPU-hotplug functions. The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock(). Replace deprecated CPU-hotplug functions with the official version. The behavior remains unchanged.
