Hi,

I've a question regarding the handling of multiple MSI Vectors on a Freescale P1022. In arch_setup_msi_irqs (arch/powerpc/kernel/msi.c) there is a comment that PowerPC doesn't support multiple MSI yet.

What is the reason for this comment and is there anything I can do to enable multiple MSI IRQs?

Thanks,
Johannes
