Maybe just make this test x86 specific for now? Doh, that's obvious in hindsight. I think the basic premise is also broken on arm64 as it returns -EFAULT on is_error_noslot_pfn(pfn). So yeah, x86 only for now :-( _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
