While doing some source review I noticed what appears to be
an extraneous call to pc_allocate_cpu_irq() in qemu-kvm and
which does not appear in qemu.  From the git history it almost
looks like b725a661eb38c93086e0b98f626a3864ae8651b8 mis-merged
845773ab03a8dde681ff1b929bbb41e67d0131a6?  At any rate qemu-kvm got
patched differently than qemu for the piix split out and this line
appears to allocate something which then goes unused.
