Subject: [PATCH 4.9 031/130] ARC: Enable machine_desc->init_per_cpu for !CONFIG_SMP

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexey Brodkin <Alexey.Brodkin@...opsys.com>

[ Upstream commit 2f24ef7413a4d91657ef04e77c27ce0b313e6c95 ]

machine_desc->init_per_cpu() hook is supposed to be per cpu
initialization and would seem to apply  equally to UP and/or SMP.
Infact the comment in header file seems to suggest it works for
UP too, which was not the case and this patch.

This enables !CONFIG_SMP build for platforms such as hsdk.
