[PATCH 5/6] ARM64: Remove arm_pm_restart()

From: Thierry Reding <hidden>
Date: 2017-01-30 11:05:41
Also in: lkml
Subsystem: arm64 port (aarch64 architecture), the rest · Maintainers: Catalin Marinas, Will Deacon, Linus Torvalds

From: Guenter Roeck <linux@roeck-us.net>

All users of arm_pm_restart() have been converted to use the kernel
restart handler.
