From 37e64e5ae1a9554762b6ec494871adcf48be20cf Mon Sep 17 00:00:00 2001 From: Mikael Pettersson Date: Wed, 5 Jul 2006 20:42:58 -0700 Subject: [SPARC64]: Fix stack overflow checking in modular non-SMP kernels. The sparc64 kernel's EXPORT_SYMBOL(_mcount) is inside an #ifdef CONFIG_SMP. This breaks modules in non-SMP kernels built with stack overflow checking (CONFIG_STACK_DEBUG=y), as modules_install reports: WARNING: /lib/modules/2.6.17/kernel/drivers/ide/ide-cd.ko needs unknown symbol _mcount Trivially fixed by moving EXPORT_SYMBOL(_mcount) outside of the #ifdef CONFIG_SMP.
