From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kishon Vijay Abraham I Subject: [PATCH v2 12/26] PCI: keystone: Prevent ARM32 specific code to be compiled for ARM64 Date: Mon, 25 Mar 2019 14:04:47 +0530 Message-ID: <20190325083501.8088-13-kishon@ti.com> References: <20190325083501.8088-1-kishon@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <20190325083501.8088-1-kishon@ti.com> Sender: linux-kernel-owner@vger.kernel.org To: Gustavo Pimentel , Bjorn Helgaas , Rob Herring , Lorenzo Pieralisi , Arnd Bergmann , Murali Karicheri Cc: Kishon Vijay Abraham I , Jingoo Han , Greg Kroah-Hartman , linux-pci@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, linux-omap@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-arm-kernel@axis.com List-Id: devicetree@vger.kernel.org hook_fault_code is an ARM32 specific API for hooking into data abort. Since pci-keystone.c will be used for AM65X platforms which is an ARM64 platform, allow hook_fault_code to be compiled only for ARM32.
