From 952f4ca79b4ec7114291aa711add1b36c6ba7515 Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Mon, 14 Apr 2014 17:10:07 +0200 Subject: [PATCH] ARM: mvebu: Remove the unused argument of set_cpu_coherent() set_cpu_coherent() took the SMP group ID as parameter. But this parameter was never used, and the CPU always uses the SMP group 0. So we can remove this parameter.
