From ea3d5226f52ef30f52aa0a04f47f5919c7facacf Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 26 Feb 2007 09:21:46 -0800 Subject: Revert "[PATCH] i386: add idle notifier" This reverts commit 2ff2d3d74705d34ab71b21f54634fcf50d57bdd5. Uwe Bugla reports that he cannot mount a floppy drive any more, and Jiri Slaby bisected it down to this commit. Benjamin LaHaise also points out that this is a big hot-path, and that interrupt delivery while idle is very common and should not go through all these expensive gyrations. Fix up conflicts in arch/i386/kernel/apic.c and arch/i386/kernel/irq.c due to other unrelated irq changes.
