From 70da1d01edf6da3fde1df98b2125a77083a0fb82 Mon Sep 17 00:00:00 2001 From: Vlastimil Babka Date: Mon, 2 Oct 2023 16:36:55 +0200 Subject: cpu/hotplug: remove CPUHP_SLAB_PREPARE hooks The CPUHP_SLAB_PREPARE hooks are only used by SLAB which is removed. SLUB defines them as NULL, so we can remove those altogether.
