This is only on i386 (32-bit x86...)[1] On x86-64, we have 8K kernel stacks (THREAD_ORDER 1), and 16K irqstacks (IRQSTACK_ORDER 2). The relevant defines are found in <asm-x86/page_64.h> for x86_64, and <asm-x86/thread_info_32.h> for i386. Cheers, Kyle 1. That is, stack size is only configurable on 32bit. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
