The current sparc32 SMP IPI generation is implemented the cross call function. The cross call function uses IRQ15 the NMI, this is has the effect that IPIs will interrupt IRQ critical areas and hang the system. Typically on/after spin_lock_irqsave calls can be aborted. The cross call functionality must still exist to flush cache/TLBS. This patch provides CPU models a custom way to implement generation of IPIs on the generic code's request. The typical approach is to generate an IRQ for each IPI case. After this patch each sparc32 SMP CPU model needs to implement IPIs in order to function properly.
