Less trivial (and I wonder whether you've come to this from an ia64 or a powerpc direction): I notice that ia64 has more stringent REGION checks in its ia64_do_page_fault, before calling expand_stack or expand_upwards.

I think you are correct. This appears to affect powerpc only. On ia64, hugetlb lives in a completely different region and they can never step into normal stack address space. And for x86, there isn't a thing called "reserved address space" for hugetlb mapping. - Ken - 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/
