smp_call_function_single(): be slightly less stupid, fix
Impact: build fix on Alpha
kernel/up.c: In function 'smp_call_function_single':
kernel/up.c:12: error: 'cpuid' undeclared (first use in this function)
kernel/up.c:12: error: (Each undeclared identifier is reported only once
kernel/up.c:12: error: for each function it appears in.)
The typo didnt show up on x86 because 'cpuid' happens to be a
function address as well ...
