sparc: copy exported sparc64 specific header files to asm-sparc
Copy was done using the following simple script:
set -e
SPARC64="h display7seg.h envctrl.h psrcompat.h pstate.h uctx.h utrap.h watchdog.h"
for FILE in ${SPARC64}; do
if [ -f asm-sparc/$FILE ]; then
echo $FILE exist in asm-sparc
fi
cat asm-sparc64/$FILE > asm-sparc/$FILE
printf "#include <asm-sparc/$FILE>\n" > asm-sparc64/$FILE
done
The name of the copied files are added to asm-sparc/Kbuild
to keep "make headers_check" functional.
