Date: Wed, 13 Apr 2016 17:54:12 -0700 From: Yang Shi <yang.shi@...aro.org> To: will.deacon@....com, catalin.marinas@....com Cc: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linaro-kernel@...ts.linaro.org, yang.shi@...aro.org Subject: [PATCH] arm64: Kconfig: make SCHED_MC and SCHED_SMT depend on SMP SCHED_MC and SCHED_SMT are pointless when SMP is disabled. Although SMP is rarely disabled for ARM64, it looks more consistent to have such depend in Kconfig.
