Also looking into why this > builds on 32-bit x86 but not on powerpc. And the reason that it built on 32-bit x86 was that I mistakenly built only the RCU files, not the whole kernel. So I am guessing that there is something I need to merge into tip/smp/hotplug. On the other hand, removing the __GFP_NOTRACE allows this patchset to pass modest rcutorture testing on Power. ;-) Thanx, Paul -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
