Michael Ellerman b40b2386bc powerpc/Makefile: Fix ld version check with 64-bit LE-only toolchain In commit `efe0160cfd` ("powerpc/64: Linker on-demand sfpr functions for modules"), we added an ld version check early in the powerpc top-level Makefile. Because the Makefile runs before the kernel config is setup, the checks for CONFIG_CPU_LITTLE_ENDIAN etc. all take the default case. So we end up configuring ld for 32-bit big endian. That would be OK, except that for historical (or perhaps no) reason, we use 'override LD' to add the endian flags to the LD variable itself, rather than the normal approach of adding them to LDFLAGS. The end result is that when we check the ld version we run it as: $(CROSS_COMPILE)ld -EB -m elf32ppc --version This often works, unless you are using a 64-bit only and/or little endian only, toolchain. In which case you see something like: $ make defconfig powerpc64le-linux-ld: unrecognised emulation mode: elf32ppc Supported emulations: elf64lppc elf32lppc elf32lppclinux elf32lppcsim /bin/sh: 1: [: -ge: unexpected operator The proper fix is to stop using 'override LD', but that will require a fair bit of testing. Instead we can fix it for now just by reordering the Makefile to do the version check earlier.

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.
