Hello!

Yes, it shouldn't. I didn't pass it there exactly because of this reason.
However, &kroute is also passed to this function, so
setting ARM-specific data could be moved there. I mean this repeating sequence
(see vITS RFC 4/6 -
https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg07075.html):
--- cut ---
kroute.flags = kvm_msi_flags;
if (kroute.flags & KVM_MSI_VALID_DEVID) {
kroute.u.msi.devid = pci_requester_id(dev);
}
--- cut ---
