      asm-generic: remove unused asm-generic/page.h · e3dff9c8
      Arnd Bergmann authored
      This file was used by c6x and blackfin in the past, but no architecture uses
      it any more, and it is only useful for architectures that do not support
      an MMU in the first place.

      arch: Rename fbdev header and source files · 2fd001cd
      Thomas Zimmermann authored
      The per-architecture fbdev code has no dependencies on fbdev and can
      be used for any video-related subsystem. Rename the files to 'video'.
      Use video-sti.c on parisc as the source file depends on CONFIG_STI_CORE.
      
      On arc, arm, arm64, sh, and um the asm header file is an empty wrapper
      around the file in asm-generic. Let Kbuild generate the file. The build
      system does this automatically. Only um needs to generate video.h
      explicitly, so that it overrides the host architecture's header. The
      latter would otherwise interfere with the build.
      
      Further update all includes statements, include guards, and Makefiles.
      Also update a few strings and comments to refer to video instead of
      fbdev.
      
      v3:
      - arc, arm, arm64, sh: generate asm header via build system (Sam,
      Helge, Arnd)
      - um: rename fb.h to video.h
      - fix typo in commit message (Sam)

      arch: Remove struct fb_info from video helpers · f178e96d
      Thomas Zimmermann authored
      The per-architecture video helpers do not depend on struct fb_info
      or anything else from fbdev. Remove it from the interface and replace
      fb_is_primary_device() with video_is_primary_device(). The new helper
      is similar in functionality, but can operate on non-fbdev devices.

      arch: Select fbdev helpers with CONFIG_VIDEO · f25eae2c
      Thomas Zimmermann authored
      Various Kconfig options selected the per-architecture helpers for
      fbdev. But none of the contained code depends on fbdev. Standardize
      on CONFIG_VIDEO, which will allow to add more general helpers for
      video functionality.
      
      CONFIG_VIDEO protects each architecture's video/ directory. This
      allows for the use of more fine-grained control for each directory's
      files, such as the use of CONFIG_STI_CORE on parisc.

      bitops: Change function return types from long to int · 9c313ccd
      Thorsten Blum authored
      Change the return types of bitops functions (ffs, fls, and fns) from
      long to int. The expected return values are in the range [0, 64], for
      which int is sufficient.
      
      Additionally, int aligns well with the return types of the corresponding
      __builtin_* functions, potentially reducing overall type conversions.
      
      Many of the existing bitops functions already return an int and don't
      need to be changed. The bitops functions in arch/ should be considered
      separately.
      
      Adjust some return variables to match the function return types.
      
      With GCC 13 and defconfig, these changes reduced the size of a test
      kernel image by 5,432 bytes on arm64 and by 248 bytes on riscv; there
      were no changes in size on x86_64, powerpc, or m68k.
