[PATCH resend] ARC: ARC_HAS_COH_CACHES no longer relevant
From: Vineet Gupta
Date: Thu Feb 02 2017 - 12:23:37 EST
A typical SMP system expects cache coherency. Initial NPS platform
support was slated to be SMP w/o cache coherency.
However it seems the platform now selects that option, so there is no
point in keeping it around.
