      kbuild: asm-generic support · d8ecc5cd
      Sam Ravnborg 提交于
      There is an increasing amount of header files
      shared between individual architectures in asm-generic.
      To avoid a lot of dummy wrapper files that just
      include the corresponding file in asm-generic provide
      some basic support in kbuild for this.
      
      With the following patch an architecture can maintain
      a list of files in the file arch/$(ARCH)/include/asm/Kbuild
      
      To use a generic file just add:
      
              generic-y += <name-of-header-file.h>
      
      For each file listed kbuild will generate the necessary
      wrapper in arch/$(ARCH)/include/generated/asm.
      
      When installing userspace headers a wrapper is likewise created.
      
      The original inspiration for this came from the unicore32
      patchset - although a different method is used.
      
      The patch includes several improvements from Arnd Bergmann.
      Michael Marek contributed Makefile.asm-generic.
      
      Remis Baima did an intial implementation along to achive
      the same - see https://patchwork.kernel.org/patch/13352/Signed-off-by: NSam Ravnborg <sam@ravnborg.org>
