sparc: copy sparc64 specific files to asm-sparc
Used the following script to copy the files: cd include set -e SPARC64=`ls asm-sparc64` for FILE in ${SPARC64}; do if [ -f asm-sparc/$FILE ]; then echo $FILE exist in asm-sparc else git mv asm-sparc64/$FILE asm-sparc/$FILE printf "#include <asm-sparc/$FILE>\n" > asm-sparc64/$FILE git add asm-sparc64/$FILE fi done Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
