[2/2] tools include: Add mman macros needed by perf for all arch

Some macros required by tools/perf/trace/beauty/mmap.c is not support
for all architectures. For example, MAP_32BIT is defined on x86 only,
alpha doesn't define MADV_HWPOISON and MADV_SOFT_OFFLINE.

This patch regenerates mman.h for each archs, defines these missing
macros for perf. For missing MADV_*, fall back to asm-generic/mman-common
because they are in 'case ...' statement. For flags, define to 0.

Following is the script to generate this patch:

 macros=`cat $0 | awk 'V==1 {print}; /^# start macro list/ {V=1}'`
 rm `find ./tools/arch/ -name mman.h`
 for arch in `ls tools/arch`
 do
   [ -d tools/arch/$arch/include/uapi/asm ] || mkdir -p tools/arch/$arch/include/uapi/asm
   src=arch/$arch/include/uapi/asm/mman.h
   target=tools/arch/$arch/include/uapi/asm/mman.h.tmp
   real_target=tools/arch/$arch/include/uapi/asm/mman.h
   guard="TOOLS_ARCH_"`echo $arch | awk '{print toupper($0)}'`_UAPI_ASM_MMAN_FIX_H
   rm -f $target

   [ -f $src ] &&
   for m in $macros
   do
     if grep '#define[ \t]*'$m $src > /dev/null 2>&1
     then
       grep -h '#define[ \t]*'$m $src | sed 's/[ \t]*\/\*.*$//g' >> $target
     fi
   done

   if [ -f $src ]
   then
      grep '#include <asm-generic' $src >> $target
   else
      echo "#include <asm-generic/mman.h>" >> $target
   fi

   touch $real_target
   for m in $macros
   do
     if cat << EOF | gcc -Itools/arch/$arch/include -Itools/arch/$arch/include/uapi -Iinclude/ -Iinclude/uapi -E - | grep $m > /dev/null 2>&1
 #include <uapi/asm/mman.h.tmp>
 #include <uapi/linux/mman.h>
 $m
 EOF
   then
     echo "Fixing $m for $arch"
     echo "/* $m is undefined on $arch, fix it for perf */" >> $target
     if echo $m | grep '^MADV_' > /dev/null 2>&1
     then
       grep -h '#define[ \t]*'$m include/uapi/asm-generic/mman-common.h | sed 's/[ \t]*\/\*.*$//g' >> $target
     else
       echo "#define $m	0" >> $target
     fi
   fi
   done

   real_target=tools/arch/$arch/include/uapi/asm/mman.h
   echo '#ifndef '$guard > $real_target
   echo '#define '$guard >> $real_target
   cat $target | sed 's|asm-generic|uapi/asm-generic|g' >> $real_target
   echo '#endif' >> $real_target
   rm $target
   echo "$real_target"
 done
