From 712610725c48c829e42bebfc9908cd92468e2731 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 4 Mar 2024 11:12:22 +0100 Subject: smp: Consolidate smp_prepare_boot_cpu() There is no point in having seven architectures implementing the same empty stub. Provide a weak function in the init code and remove the stubs. This also allows to utilize the function on UP which is required to sanitize the per CPU handling on X86 UP.
