From c8d2bcc467c8a1a85983c24e0331cf19fe94668f Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 12 May 2023 23:07:37 +0200 Subject: MIPS: SMP_CPS: Switch to hotplug core state synchronization Switch to the CPU hotplug core state tracking and synchronization mechanim. This unfortunately requires to add dead reporting to the non CPS platforms as CPS is the only user, but it allows an overall consolidation of this functionality. No functional change intended.
