+uapi/linux/irqnr.h was emitted by the UAPI disintegration script as an empty
+file because the parent linux/irqnr.h had no UAPI stuff in it, despite being
+marked with "header-y".
+
+Unfortunately, it patch deletes the empty file when applying a kernel patch.
+
+It's not clear why this file is part of the UAPI at all.  Looking in:
+
+	/usr/include/linux/irqnr.h
+
+there's nothing there but a header reinclusion guard and a comment.
+
+So just stick a comment in there as a placeholder.
+
+Without this, if the kernel is fabricated from, say, a tarball and a patch, you
+can get this error when building x86_64 or usermode Linux (and probably
+others):
+
+include/linux/irqnr.h:4:30: fatal error: uapi/linux/irqnr.h: No such file or directory
