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
