[ Upstream commit f316a2b53cd7f37963ae20ec7072eb27a349a4ce ] hook_fault_code() is an ARM32 specific API for hooking into data abort. AM65X platforms (that integrate ARM v8 cores and select CONFIG_ARM64 as arch) rely on pci-keystone.c but on them the enumeration of a non-present BDF does not trigger a bus error, so the fixup exception provided by calling hook_fault_code() is not needed and can be guarded with CONFIG_ARM.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
