ACPI processor: Use safe_halt() rather than halt() in acpi_idle_play_dead()
ACPI code is shared by arch/x86 and arch/ia64. ia64 doesn't provide a plain "halt()" function. Use safe_halt() instead. Signed-off-by: Tony Luck <tony.luck@intel.com> Tested-by: Boris Ostrovsky <boris.ostrovsky@amd.com> Signed-off-by: Len Brown <len.brown@intel.com>
