Subject: [SPARC64]: Fix stack overflow checking in modular non-SMP kernels.
X-Git-Tag: v2.6.18-rc1~2^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=37e64e5ae1a9554762b6ec494871adcf48be20cf;p=pandora-kernel.git

[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.
