From 4b3dc9679cf779339d9049800803dfc3c83433d1 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 29 May 2015 18:28:44 +0100 Subject: arm64: force CONFIG_SMP=y and remove redundant #ifdefs Nobody seems to be producing !SMP systems anymore, so this is just becoming a source of kernel bugs, particularly if people want to use coherent DMA with non-shared pages. This patch forces CONFIG_SMP=y for arm64, removing a modest amount of code in the process.
