From bd8559c38ee5be40ce2c57a80fd3c3e978cca267 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Wed, 2 May 2007 19:27:11 +0200 Subject: [PATCH] x86: remove UNEXPECTED_IO_APIC() Many years ago, UNEXPECTED_IO_APIC() contained printk()'s (but nothing more). Now that it's completely empty for years, we can as well remove it.
