From dab16ae1a9fc72a9f419f2dff91854e452d02a5e Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Tue, 5 Jul 2011 16:29:40 +0200 Subject: [PATCH] m32r: Use generic PREEMPT config Use the generic preempt config definition in m32r instead of using a custom one. This also makes it handle the new CONFIG_PREEMPT_COUNT that need to be selected by CONFIG_PREEMPT. Without that it breaks kernel/sched.c: In function 'preempt_schedule': kernel/sched.c:4364: error: implicit declaration of function 'add_preempt_count_notrace' kernel/sched.c:4366: error: implicit declaration of function 'sub_preempt_count_notrace' Reported-by: Ingo Molnar Signed-off-by: Frederic Weisbecker Cc: Hirokazu Takata --- arch/m32r/Kconfig | 12 +----------- 1 file changed, 1 insertion(+), 11 deletions(-) diff --git a/arch/m32r/Kconfig b/arch/m32r/Kconfig index 85b44e858225..b92b9445255d 100644 --- a/arch/m32r/Kconfig +++ b/arch/m32r/Kconfig @@ -268,17 +268,7 @@ config SCHED_OMIT_FRAME_POINTER bool default y -config PREEMPT - bool "Preemptible Kernel" - help - This option reduces the latency of the kernel when reacting to - real-time or interactive events by allowing a low priority process to - be preempted even if it is in kernel mode executing a system call. - This allows applications to run more reliably even when the system is - under load. - - Say Y here if you are building a kernel for a desktop, embedded - or real-time system.
