ARM: call machine_shutdown() from machine_halt(), etc
x86 calls machine_shutdown() from the various machine_*() calls which take the machine down ready for halting, restarting, etc, and uses this to bring the system safely to a point where those actions can be performed. Such actions are stopping the secondary CPUs. So, change the ARM implementation of these to reflect what x86 does. This solves kexec problems on ARM SMP platforms, where the secondary CPUs were left running across the kexec call. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
