And if it was that would be a problem because\nthere are implications in letting userspace do paste, so can you drop\nthis from the series for now.\n\ncheers","headers":{"Return-Path":"","X-Original-To":["patchwork-incoming@ozlabs.org","linuxppc-dev@lists.ozlabs.org"],"Delivered-To":["patchwork-incoming@ozlabs.org","linuxppc-dev@lists.ozlabs.org","linuxppc-dev@ozlabs.org"],"Received":["from lists.ozlabs.org (lists.ozlabs.org [IPv6:2401:3900:2:1::3])\n\t(using TLSv1.2 with cipher ADH-AES256-GCM-SHA384 (256/256 bits))\n\t(No client certificate requested)\n\tby ozlabs.org (Postfix) with ESMTPS id 3xdx1n0yRKz9t1G\n\tfor ;\n\tFri, 25 Aug 2017 19:38:53 +1000 (AEST)","from lists.ozlabs.org (lists.ozlabs.org [IPv6:2401:3900:2:1::3])\n\tby lists.ozlabs.org (Postfix) with ESMTP id 3xdx1m70H4zDqgq\n\tfor ;\n\tFri, 25 Aug 2017 19:38:52 +1000 (AEST)","from ozlabs.org (ozlabs.org [IPv6:2401:3900:2:1::2])\n\t(using TLSv1.2 with cipher ADH-AES256-GCM-SHA384 (256/256 bits))\n\t(No client certificate requested)\n\tby lists.ozlabs.org (Postfix) with ESMTPS id 3xdwzZ4tjDzDrWL\n\tfor ;\n\tFri, 25 Aug 2017 19:36:58 +1000 (AEST)","by ozlabs.org (Postfix)\n\tid 3xdwzZ3psxz9sP5; Fri, 25 Aug 2017 19:36:58 +1000 (AEST)","from authenticated.ozlabs.org (localhost [127.0.0.1])\n\t(using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128\n\tbits)) (No client certificate requested)\n\tby ozlabs.org (Postfix) with ESMTPSA id 3xdwzZ20nRz9sNd;\n\tFri, 25 Aug 2017 19:36:58 +1000 (AEST)"],"From":"Michael Ellerman ","To":"Sukadev Bhattiprolu ","Subject":"Re: [PATCH v7 07/12] powerpc/vas: Define vas_win_paste_addr()","In-Reply-To":"<1503556688-15412-8-git-send-email-sukadev@linux.vnet.ibm.com>","References":"<1503556688-15412-1-git-send-email-sukadev@linux.vnet.ibm.com>\n\t<1503556688-15412-8-git-send-email-sukadev@linux.vnet.ibm.com>","User-Agent":"Notmuch/0.21 (https://notmuchmail.org)","Date":"Fri, 25 Aug 2017 19:36:57 +1000","Message-ID":"<8760dcugxy.fsf@concordia.ellerman.id.au>","MIME-Version":"1.0","Content-Type":"text/plain","X-BeenThere":"linuxppc-dev@lists.ozlabs.org","X-Mailman-Version":"2.1.23","Precedence":"list","List-Id":"Linux on PowerPC Developers Mail List\n\t","List-Unsubscribe":",\n\t","List-Archive":"","List-Post":"","List-Help":"","List-Subscribe":",\n\t","Cc":"stewart@linux.vnet.ibm.com, mikey@neuling.org, linuxppc-dev@ozlabs.org, \n\tlinux-kernel@vger.kernel.org, apopple@au1.ibm.com, oohall@gmail.com","Errors-To":"linuxppc-dev-bounces+patchwork-incoming=ozlabs.org@lists.ozlabs.org","Sender":"\"Linuxppc-dev\"\n\t"}}]
