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 arch, defines these missing
macros for perf. For missing MADV_*, fall back to asm-generic/mman-common
because they are in a 'case ...' statement. For flags, define it 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
