From e64a3cfcd929d093a2f076bcace9afa7ba5a2e32 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Thu, 20 Mar 2008 20:59:34 +0300 Subject: [PATCH] [MIPS] Make KGDB compile on UP Building UP kernel with KGDB enabled produces the following errors and warning (fatal due to -Werror in arch/mips/kernel/Makefile): In file included from arch/mips/kernel/gdb-stub.c:142: include/asm/smp.h:25:1: "raw_smp_processor_id" redefined In file included from include/linux/sched.h:69, from arch/mips/kernel/gdb-stub.c:126: include/linux/smp.h:88:1: this is the location of the previous definition In file included from arch/mips/kernel/gdb-stub.c:142: include/asm/smp.h:62: error: redefinition of 'smp_send_reschedule' include/linux/smp.h:102: error: previous definition of 'smp_send_reschedule' was here include/asm/smp.h: In function `smp_send_reschedule': include/asm/smp.h:65: error: dereferencing pointer to incomplete type arch/mips/kernel/gdb-stub.c: At top level: arch/mips/kernel/gdb-stub.c:660: warning: 'kgdb_wait' defined but not used Fix the errors by not directly including (which is already included by ) and the warning by enclosing kgdb_wait() in #ifdef CONFIG_SMP.
