Breaks sparc64 and probably lots of other architectures: mm/ksm.c: In function `try_to_merge_two_pages_alloc': mm/ksm.c:697: error: `_PAGE_RW' undeclared (first use in this function) there should be an official arch-independent way of manipulating vma->vm_page_prot, but I'm not immediately finding it. An alternative (and quite inferior) "fix" would be to disable ksm on architectures which don't implement _PAGE_RW. That's most of them. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
