[ Upstream commitb929926f01] Fix this by defining both ENDIAN macros in <asm/sfp-machine.h> so that they can be utilized in <math-emu/soft-fp.h> according to the latter's comment: /* Allow sfp-machine to have its own byte order definitions. */ (This is what is done in arch/nds32/include/asm/sfp-machine.h.) This placates these build warnings: In file included from ../arch/sh/math-emu/math.c:23: .../include/math-emu/single.h:50:21: warning: "__BIG_ENDIAN" is not defined, evaluates to 0 [-Wundef] 50 | #if __BYTE_ORDER == __BIG_ENDIAN In file included from ../arch/sh/math-emu/math.c:24: .../include/math-emu/double.h:59:21: warning: "__BIG_ENDIAN" is not defined, evaluates to 0 [-Wundef] 59 | #if __BYTE_ORDER == __BIG_ENDIAN Fixes:4b565680d1("sh: math-emu support") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Cc: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Tested-by: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> Signed-off-by: Rich Felker <dalias@libc.org> 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.
