[RFC PATCH 00/11] smp: Single IPI cleanups

[Frederic Weisbecker <fweisbec@gmail.com>]

Hi,

Here is a batch of cleanups on the generic single IPI code. I've
gathered a few patches from Jan, split up some, and added a few more
so that __smp_call_function_single() becomes less obscure.

Comments?

Thanks,
