Message-ID: <175697833458.1920.7264544067265920731.tip-bot2@tip-bot2> Date: Thu, 04 Sep 2025 09:32:14 -0000 From: tip-bot2 for Thomas Weißschuh <tip-bot2@...utronix.de> To: linux-tip-commits@...r.kernel.org Cc: thomas.weissschuh@...utronix.de, Thomas Gleixner <tglx@...utronix.de>, Catalin Marinas <catalin.marinas@....com>, x86@...nel.org, linux-kernel@...r.kernel.org Subject: [tip: timers/vdso] vdso: Drop Kconfig GENERIC_VDSO_TIME_NS The following commit has been merged into the timers/vdso branch of tip: Commit-ID: bad53ae2dc4296acb8cbcee385e0238cea484100 Gitweb: https://git.kernel.org/tip/bad53ae2dc4296acb8cbcee385e0238cea484100 Author: Thomas Weißschuh <thomas.weissschuh@...utronix.de> AuthorDate: Tue, 26 Aug 2025 08:17:13 +02:00 Committer: Thomas Gleixner <tglx@...utronix.de> CommitterDate: Thu, 04 Sep 2025 11:23:50 +02:00 vdso: Drop Kconfig GENERIC_VDSO_TIME_NS All architectures implementing time-related functionality in the vDSO are using the generic vDSO library which handles time namespaces properly. Remove the now unnecessary Kconfig symbol. Enables the use of time namespaces on architectures, which use the generic vDSO but did not enable GENERIC_VDSO_TIME_NS, namely MIPS and arm.
