Date: Tue, 10 Aug 2021 12:52:01 -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: x86/cleanups] x86/mtrr: Replace deprecated CPU-hotplug functions. The following commit has been merged into the x86/cleanups branch of tip: Commit-ID: 1a351eefd4acc97145903b1c07e4d8b626854b82 Gitweb: https://git.kernel.org/tip/1a351eefd4acc97145903b1c07e4d8b626854b82 Author: Sebastian Andrzej Siewior <bigeasy@...utronix.de> AuthorDate: Tue, 03 Aug 2021 16:15:50 +02:00 Committer: Thomas Gleixner <tglx@...utronix.de> CommitterDate: Tue, 10 Aug 2021 14:46:27 +02:00 x86/mtrr: 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.
