From 1f82e1240eba4b31091bcff0e3c126853adacb53 Mon Sep 17 00:00:00 2001 From: Stefan Hengelein Date: Tue, 2 Sep 2014 19:55:11 +0200 Subject: [PATCH] init/Kconfig: move RCU_NOCB_CPU dependencies to choice Every choice item of the "Build-forced no-CBs CPUs" choice had a dependency to RCU_NOCB_CPU. It's more comprehensible if the choice itself has the dependency instead of every choice item. The choice itself doesn't need to be visible if there are no items selectable (i.e. on arch/frv) or RCU_NOCB_CPU is not defined.
