+This reverts commit 36ae3c0a36b7456432fedce38ae2f7bd3e01a563.
+
+The commit broke compilation on !CONFIG_HAVE_KVM_IRQ_ROUTING. Also,
+there may be cases with CONFIG_HAVE_KVM_IRQ_ROUTING, where larger
+gsi values make sense.
+
+As the commit was meant as an early indicator to user space that
+something is wrong, reverting just restores the previous behavior
+where overly large values are ignored when encountered (without
+any direct feedback).
