This reverts commit 1b39e3f813b4685c7a30ae964d5529a1b0e3a286.

Makes my P3 machine oops somewhere in cpuidle. I suspect
CONFIG_ACPI=n may have something to do with this.

And if you don't do CONFIG_ACPI=n, does it still oops?

Don't think I actually tried that. I can give it a whirl tonight.

I think this machine should actually have ACPI, but it inherited
the .config from a P2 machine that did not. Apparently I was too
lazy to change .config when I swapped in the "new" machine.

Anyway, there are later changes depending on this one, so reverting it
won't work in general.

Let me look deeper at this.

What's there in /sys/devices/system/cpu/cpuidle/current_driver on your
system with the problematic commit reverted?

# cat /sys/devices/system/cpu/cpuidle/current_driver
apm_idle
