Used the following script to find equal header files:
SPARC64=`ls asm-sparc64`
for FILE in ${SPARC64}; do
	cmp -s asm-sparc/$FILE asm-sparc64/$FILE;
	if [ $? = 0 ]; then
		printf "#include <asm-sparc/%s>\n" $FILE > asm-sparc64/$FILE
	fi
done

A few of the equal files are a simple include from
asm-generic, but by including the file from asm-sparc
we know they are equal for sparc and sparc64.
