sparc32,leon: Implemented SMP IPIs for LEON CPU This patch implements SMP IPIs on LEON using software generated IRQs to signal between CPUs. The IPI IRQ number is set by using the ipi_num property in the device tree, or defaults to 13. LEON SMP systems should reserve IRQ 13 (and IRQ 15) to Linux in order for the defaults to work.
