Return value of function eiointc_index is int, however it is converted into uint32_t and then compared smaller than zero. This causes logic problem. There is eioint initialization problem on qemu virt-machine where there is only one eioint node and more than 4 vcpus. Nodemap of eioint is 1, and external device intr can only be routed to vcpu 0-3, the other vcpus can not response any external device interrupts and only local processor interrupts like ipi/timer can work.
