Yes, but what if it's I/O related (eg. removal/addition of I/O delay)...
That affects the entire I/O system - all hardware devices.
This is a real example FWIW.
That's why I vote the kernel-config add support for sub-cpu's
[I'd also like to see a menuconfig on other platforms - how DO you set
that up?]
[and how difficult's cross-compiling for, say, Alpha?]
