SubjectRe: [PATCH] DevFS support for /dev/cpu/X/(cpuid|msr)

And, thus, we decend into more /proc crappyness.

After *lots* of discussion and months of waiting, it was decided between
Alan, David Jones, Jeff Garzik, and other affected parties that
/proc/sys/cpu/#/whatever would be a reasonable. It has even appeared on
lkml a couple of times in the past.

Currently, there is an allocated sysctl number in include/linux/sysctl.h
for /proc/sys/cpu, and it is used by the cpufreq code to provide:

/proc/sys/cpu/#/speed
/proc/sys/cpu/#/speed-max
/proc/sys/cpu/#/speed-min

However, it's true that some of that needs to be pulled out so anything
can use /proc/sys/cpu/#. Just takes the necessary parties to get together
to do the hard work, and with the right hardware to test it out.
