The code of changing stack is under arch/i386. So at least it is considered architecture-dependent, rather than architecture-neutral. While not sure whether it is available at other architecture than x86, I think it is at least not supposed to be available at all architectures. 2007/2/5, Rajat Jain <rajat.noida.india@xxxxxxxxx>:

Or is the option only available on x86 (the stack size configurable only on x86)? I read you can configure it to one page (in which case ISR will have separate stack) or two page (in which case ISR will share stack)?
