From: Randy Dunlap <[EMAIL PROTECTED]>
smp_call_function_single() needs to be visible in non-SMP builds, to fix:
arch/x86_64/kernel/vsyscall.c:283: warning: implicit declaration of function
'smp_call_function_single'
The (other/trivial) fix (instead of this one) is to add:
#include <asm/smp.h>
to linux-2.6.19-rc6-mm2/arch/x86_64/kernel/vsyscall.c
