Most of us get just a scary-looking warning, but whatever the problem is for you, it's good to hear this patch works around it. Whatever the long-term solution will be, for 4.10 an updated[1] version of this fix is on kbuild/kbuild (and kbuild/for-next). I guess we'll bother stable@ once it is merged. Note that it handles only x86, there's a bunch of other architectures affected, alpha m68k s390 sparc ia64 might still need fixing. Meow! [1]. Turns out there was a missing symbol on 486; people build-test those but don't try to actually boot, and even when they do, they don't read warnings. -- Autotools hint: to do a zx-spectrum build on a pdp11 host, type: ./configure --host=zx-spectrum --build=pdp11 -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
