From 083986e8248d978b6c961d3da6beb0c921c68220 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Sat, 28 Sep 2013 11:23:59 +0200 Subject: mutex: replace CONFIG_HAVE_ARCH_MUTEX_CPU_RELAX with simple ifdef Linus suggested to replace #ifndef CONFIG_HAVE_ARCH_MUTEX_CPU_RELAX #define arch_mutex_cpu_relax() cpu_relax() #endif with just a simple #ifndef arch_mutex_cpu_relax # define arch_mutex_cpu_relax() cpu_relax() #endif to get rid of CONFIG_HAVE_CPU_RELAX_SIMPLE. So architectures can simply define arch_mutex_cpu_relax if they want an architecture specific function instead of having to add a select statement in their Kconfig in addition.
