SubjectRE: [PATCH 0/5] Generic smp_call_function(), improvements, and smp_call_function_single()

Having scared you to death with some of the strange weirdness of
ia64 ... it turns out that you made a trivial typo in the ia64
specific part of the patch ... see below.

With this patch and a hack to call init_call_single_data() early
enough the patch boots fine on ia64.

[IA64] Fix typo'd call to generic_smp_call_function_single_interrupt

Should really be calling generic_smp_call_function_interrupt() for
the IPI_CALL_FUNC case.
