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.
