This should avoid the overhead of using XICS to deliver an IPI within a core, though delivering IPIs between threads of different cores must still use XICS as before. Please note that this series depends on this series posted by Michael Neuling, as it adds additional relocation on exception vectors: https://lists.ozlabs.org/pipermail/linuxppc-dev/2012-November/101910.html
