sparc: join the remaining header files With this commit all sparc64 header files are moved to asm-sparc. The remaining files (71 files) were too different to be trivially merged so divide them up in a _32.h and a _64.h file which are both included from the file with no bit size. The following script were used: cd include FILES=`wc -l asm-sparc64/*h | grep -v '^ 1' | cut -b 20-` for FILE in ${FILES}; do echo $FILE: BASE=`echo $FILE | cut -d '.' -f 1` FN32=${BASE}_32.h FN64=${BASE}_64.h GUARD=___ASM_SPARC_`echo $BASE | tr '-' '_' | tr [:lower:] [:upper:]`_H git mv asm-sparc/$FILE asm-sparc/$FN32 git mv asm-sparc64/$FILE asm-sparc/$FN64 echo git mv done printf "#ifndef %s\n" $GUARD > asm-sparc/$FILE printf "#define %s\n" $GUARD >> asm-sparc/$FILE printf "#if defined(__sparc__) && defined(__arch64__)\n" >> asm-sparc/$FILE printf "#include <asm-sparc/%s>\n" $FN64 >> asm-sparc/$FILE printf "#else\n" >> asm-sparc/$FILE printf "#include <asm-sparc/%s>\n" $FN32 >> asm-sparc/$FILE printf "#endif\n" >> asm-sparc/$FILE printf "#endif\n" >> asm-sparc/$FILE git add asm-sparc/$FILE echo new file done printf "#include <asm-sparc/%s>\n" $FILE > asm-sparc64/$FILE git add asm-sparc64/$FILE echo sparc64 file done done The guard contains three '_' to avoid conflict with existing guards. In additing the two Kbuild files are emptied to avoid breaking headers_* targets. We will reintroduce the exported header files when the necessary kbuild changes are merged.

sparc, sparc64: use arch/sparc/include The majority of this patch was created by the following script: *** ASM=arch/sparc/include/asm mkdir -p $ASM git mv include/asm-sparc64/ftrace.h $ASM git rm include/asm-sparc64/* git mv include/asm-sparc/* $ASM sed -ie 's/asm-sparc64/asm/g' $ASM/* sed -ie 's/asm-sparc/asm/g' $ASM/* *** The rest was an update of the top-level Makefile to use sparc for header files when sparc64 is being build. And a small fixlet to pick up the correct unistd.h from sparc64 code. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
