From 1e42176b4dac328b0be7075c2cebdf2006d31eb3 Mon Sep 17 00:00:00 2001 From: Qais Yousef Date: Mon, 23 Mar 2020 13:50:56 +0000 Subject: ia64: Replace cpu_down() with smp_shutdown_nonboot_cpus() Use the new smp_shutdown_nonboot_cpus() instead of using cpu_down() directly. Use reboot_cpu instead of hardcoding the boot CPU to 0. This also prepares to make cpu_up/down() a private interface of the CPU subsystem.
