From mboxrd@z Thu Jan 1 00:00:00 1970 From: James Hogan Subject: [PATCH 5/5] tile: Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO Date: Mon, 25 Jul 2016 16:59:54 +0100 Message-ID: <1469462394-8970-6-git-send-email-james.hogan@imgtec.com> References: <1469462394-8970-1-git-send-email-james.hogan@imgtec.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Received: from mailapp01.imgtec.com ([195.59.15.196]:55688 "EHLO mailapp01.imgtec.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753356AbcGYQAX (ORCPT ); Mon, 25 Jul 2016 12:00:23 -0400 In-Reply-To: <1469462394-8970-1-git-send-email-james.hogan@imgtec.com> Sender: linux-arch-owner@vger.kernel.org List-ID: To: linux-arch@vger.kernel.org Cc: linux-kernel@vger.kernel.org, James Hogan , Chris Metcalf AT_VECTOR_SIZE_ARCH should be defined with the maximum number of NEW_AUX_ENT entries that ARCH_DLINFO can contain, but it wasn't defined for tile at all even though ARCH_DLINFO will contain one NEW_AUX_ENT for the VDSO address. This shouldn't be a problem as AT_VECTOR_SIZE_BASE includes space for AT_BASE_PLATFORM which tile doesn't use, but lets define it now and add the comment above ARCH_DLINFO as found in several other architectures to remind future modifiers of ARCH_DLINFO to keep AT_VECTOR_SIZE_ARCH up to date.
