Hi Liquin, Have you had a chance to look at the asm-generic header files I posted a few times? I think it would be ideal if you can change your code to use the asm-generic version whereever possible, by replacing your files with something like arch/score/include/asm/foo.h: #include <asm-generic/foo.h> In particular, all of the exported header files that get included in user space should use only the asm-generic version, with the exception of byteorder.h, elf.h and ptrace.h, which are by definition architecture specific. Please tell me if you find problems in the generic header files during the conversion.
