acpi-test tree build failure

I tried acpi-test to see how it works on my EeePC (with the nasty EC), but the build fails, complaining about a non-existent file...

    $ make ARCH=i386 oldconfig
    scripts/kconfig/conf -o arch/x86/Kconfig
    arch/x86/Kconfig:1539: can't open file "drivers/idle/Kconfig"
    make[1]: *** [oldconfig] Error 1
    make: *** [oldconfig] Error 2

I can see where the reference to drivers/idle was added, so I've reverted it locally. I hope I'm not looking at the wrong tree or something :-).

Ta,
Alan

i7300_idle driver v1.55

The Intel 7300 Memory Controller supports dynamic throttling of
memory which can
be used to save power when system is idle. This driver does the memory throttling when all CPUs are idle on such a system.

Refer to "Intel 7300 Memory Controller Hub (MCH)" datasheet for the config space description.

it was a real bug.
probably i forgot to manually add this file, which git makes me do when i resolve merge conflicts. didn't notice it b/c the untracked Kconfig file was still sitting there when I needed it.

thanks,
