updated patch below - i left out the cpu.h bits because they caused
problems elsewhere.

Subject: x86_64: build fixes
From: Ingo Molnar <[EMAIL PROTECTED]>
x86_64 does not build cleanly on UP:
arch/x86_64/kernel/vsyscall.c: In function 'cpu_vsyscall_notifier':
arch/x86_64/kernel/vsyscall.c:282: warning: implicit declaration of function
'smp_call_function_single'
arch/x86_64/kernel/vsyscall.c: At top level:
arch/x86_64/kernel/vsyscall.c:279: warning: 'cpu_vsyscall_notifier' defined but
not used
this patch fixes it.
