    Revert "[PATCH] i386: add idle notifier" · ea3d5226
    Linus Torvalds authored
    This reverts commit 2ff2d3d7.
    
    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.
