Sam Ravnborg f5e706ad88 sparc: join the remaining header files 
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.
