[ Upstream commit 345dac33f58894a56d17b92a41be10e16585ceff ] When configuring the kernel for big-endian, we set either BE-8 or BE-32 based on the CPU architecture level. Until linux-4.4, we did not have any ARMv7-M platform allowing big-endian builds, but now i.MX/Vybrid is in that category, adn we get a build error because of this: arch/arm/kernel/module-plts.c: In function 'get_module_plt': arch/arm/kernel/module-plts.c:60:46: error: implicit declaration of function '__opcode_to_mem_thumb32' [-Werror=implicit-function-declaration] This comes down to picking the wrong default, ARMv7-M uses BE8 like ARMv7-A does. Changing the default gets the kernel to compile and presumably works. https://lore.kernel.org/all/1455804123-2526139-2-git-send-email-arnd@arndb.de/ Tested-by: Vladimir Murzin <vladimir.murzin@arm.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
