From 7ed40918a386afc2e14a6d3da563ea6d13686c25 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 6 Jan 2006 08:43:16 -0800 Subject: [PATCH] x86: remove bogus 'pci=usepirqmask' suggestion when no irq is defined This was harmless, but for the case of a device that had no irq pre-defined we would incorrectly suggest that "usepirqmask" might make a difference. It never would, and the message was just confusing people. Reported in the dmesg of Etienne Lorrain.
