From bb74b734a68544ad8f1537a33a7e22c73c87ed1c Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sat, 13 Oct 2007 23:27:48 -0700 Subject: [PATCH] [SPARC64]: Kill ugly __irq_ino() macro. We have a place to stick INO information in the virt_to_real_irq_table[], which is currently only used for VIRQs. And that is readily accessible from the one __irq_ino() call site.
