From 33c3736ec88811b9b6f6ce2cc8967f6b97c3db5e Mon Sep 17 00:00:00 2001 From: Qais Yousef Date: Mon, 23 Mar 2020 13:51:10 +0000 Subject: cpu/hotplug: Hide cpu_up/down() Use separate functions for the device core to bring a CPU up and down. Users outside the device core must use add/remove_cpu() which will take care of extra housekeeping work like keeping sysfs in sync. Make cpu_up/down() static and replace the extra layer of indirection.
