MO_BE : MO_LE\".\n\nI think there should be no need for CONFIG_USER_ONLY tests. I'm not sure what's still \ndifferent between user and system modes there. Unfortunately, testing of BE32 might be \nimpossible at this point due to armv4be dropping off support lists.\n\n\nr~","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@legolas.ozlabs.org","Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=linaro.org header.i=@linaro.org header.a=rsa-sha256\n header.s=google header.b=REsKWHhq;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=nongnu.org\n (client-ip=209.51.188.17; helo=lists.gnu.org;\n envelope-from=qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org;\n receiver=patchwork.ozlabs.org)"],"Received":["from lists.gnu.org (lists.gnu.org [209.51.188.17])\n\t(using TLSv1.2 with cipher ECDHE-ECDSA-AES256-GCM-SHA384 (256/256 bits))\n\t(No client certificate requested)\n\tby legolas.ozlabs.org (Postfix) with ESMTPS id 4fqP642dDZz1y2d\n\tfor ; Tue, 07 Apr 2026 08:25:16 +1000 (AEST)","from localhost ([::1] helo=lists1p.gnu.org)\n\tby lists.gnu.org with esmtp (Exim 4.90_1)\n\t(envelope-from )\n\tid 1w9sNM-0004Vg-IJ; Mon, 06 Apr 2026 18:24:56 -0400","from eggs.gnu.org ([2001:470:142:3::10])\n by lists.gnu.org with esmtps (TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256)\n (Exim 4.90_1) (envelope-from )\n id 1w9sNL-0004SD-EL\n for qemu-devel@nongnu.org; Mon, 06 Apr 2026 18:24:55 -0400","from mail-pf1-x42c.google.com ([2607:f8b0:4864:20::42c])\n by eggs.gnu.org with esmtps (TLS1.2:ECDHE_RSA_AES_128_GCM_SHA256:128)\n (Exim 4.90_1) (envelope-from )\n id 1w9sNJ-0007r1-RA\n for qemu-devel@nongnu.org; Mon, 06 Apr 2026 18:24:55 -0400","by mail-pf1-x42c.google.com with SMTP id\n d2e1a72fcca58-82ce49785a0so1813501b3a.2\n for ; Mon, 06 Apr 2026 15:24:53 -0700 (PDT)","from [192.168.1.105] (124-150-69-109.tpgi.com.au.
