| From | Qais Yousef <> | Subject | [PATCH v4 03/17] ia64: Replace cpu_down with smp_shutdown_nonboot_cpus() | Date | Mon, 23 Mar 2020 13:50:56 +0000 |
| |
Use the new smp_shutdown_nonboot_cpus() instead of open coding 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 for anything but the cpu subsystem.
