[ Upstream commit ca8e45c8048a2c9503c74751d25414601f730580 ] The arch_jump_label_transform_static() function in csky was originally meant to override the generic __weak function, but that got changed to an #ifndef check. This showed up as a missing-prototype warning: arch/csky/kernel/jump_label.c:43:6: error: no previous prototype for 'arch_jump_label_transform_static' [-Werror=missing-prototypes] Change the method to use the new method of having a #define and a prototype for the global function. Fixes:7e6b9db27d("jump_label: make initial NOP patching the special case") Fixes:4e8bb4ba5a("csky: Add jump-label implementation") Reviewed-by: Guo Ren <guoren@kernel.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de> 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.
