[ Upstream commit a57ab96ef9dde231d4d46edba4d5f73720edc16a ] We already have memcpy_toio(), but not memset_io(), so let's add the obvious version to allow building an allmodconfig kernel without errors like drivers/gpu/drm/ttm/ttm_bo_util.c: In function 'ttm_bo_move_memcpy': drivers/gpu/drm/ttm/ttm_bo_util.c:390:3: error: implicit declaration of function 'memset_io' [-Werror=implicit-function-declaration] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Richard Kuo <rkuo@codeaurora.org> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
