Commit fbde2d7d ("MIPS: Add generic SMP IPI support") introduced a sanity check that an IPI IRQ domain can be found during boot, in order to ensure that IPIs are able to be set up in systems using such domains. However it was added at a point where systems may have used an IPI IRQ domain in some situations but not others, and we could not know which were the case until runtime, so commit 578bffc8 ("MIPS: Don't BUG_ON when no IPI domain is found") made that check simply skip IPI init if no domain were found in order to fix the boot for systems such as QEMU Malta. We now use IPI IRQ domains for the MIPS CPU interrupt controller, which means systems which make use of IPI IRQ domains will always do so when running on multiple CPUs. As a result we now strengthen the sanity check to ensure that an IPI IRQ domain is found when multiple CPUs are present in the system.
