Let me do that one better. Let's look first for the suspects.
alpha:/usr/src/linux> grep -lir IDLE /usr/src/linux/Documentation/
/usr/src/linux/Documentation/networking/z8530drv.txt
/usr/src/linux/Documentation/networking/arcnet-hardware.txt
/usr/src/linux/Documentation/networking/ifenslave.c
/usr/src/linux/Documentation/Configure.help
/usr/src/linux/Documentation/smp.tex
/usr/src/linux/Documentation/isdn/README
/usr/src/linux/Documentation/isdn/INTERFACE.fax
/usr/src/linux/Documentation/powerpc/smp.txt
/usr/src/linux/Documentation/s390/Debugging390.txt
/usr/src/linux/Documentation/sx.txt
/usr/src/linux/Documentation/sysctl/kernel.txt
/usr/src/linux/Documentation/video4linux/bttv/README.quirks
/usr/src/linux/Documentation/arm/SA1100/DMA
/usr/src/linux/Documentation/kernel-parameters.txt
/usr/src/linux/Documentation/pm.txt
So which one? I narrow down the search to include the "=" sign, which is
the form it's used as a kernel paramater.
alpha:/usr/src/linux> grep -lir IDLE= /usr/src/linux/Documentation/
/usr/src/linux/Documentation/kernel-parameters.txt
Which brings us back to where we started from, Eric's tip
("kernel-parameters.txt")

As you can see from the above the details are either not there or
hoarded in some none too obvious file.
