From 0b0517a475c2fd601d01acb4a585644eda9c9395 Mon Sep 17 00:00:00 2001 From: Satyam Sharma Date: Mon, 13 Aug 2007 23:41:45 +0530 Subject: [PATCH] [IA64] Include Kconfig.preempt arch/ia64/Kconfig failed to include kernel/Kconfig.preempt that meant it did not support PREEMPT_VOLUNTARY and PREEMPT_BKL (inadvertently). This was recently noticed when the newly-added PREEMPT_NOTIFIERS in Kconfig.preempt that was "select"ed from drivers/kvm/Kconfig (therefore) started giving bogus warnings ('select' used by config symbol 'KVM' refers to undefined symbol 'PREEMPT_NOTIFIERS') on ia64 builds. So let's remove the open-coded definition of CONFIG_PREEMPT in arch/ia64/Kconfig and replace it with just including Kconfig.preempt instead, like the other archs do.
