Subject: [PATCH] arm64: Kconfig: make SCHED_MC and SCHED_SMT depend on SMP
Date: Wed, 13 Apr 2016 17:54:12 -0700 [thread overview]
Message-ID: <1460595252-2330-1-git-send-email-yang.shi@linaro.org> (raw)
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.
