6f52b16c5b License cleanup: add SPDX license identifier to uapi header files with no license 
Many user space API headers are missing licensing information, which
makes it hard for compliance tools to determine the correct license.

By default are files without license information under the default
license of the kernel, which is GPLV2.  Marking them GPLV2 would exclude
them from being included in non GPLV2 code, which is obviously not
intended. The user space API headers fall under the syscall exception
which is in the kernels COPYING file:

   NOTE! This copyright does *not* cover user programs that use kernel
   services by normal system calls - this is merely considered normal use
   of the kernel, and does *not* fall under the heading of "derived work".

otherwise syscall usage would not be possible.

Update the files which contain no license information with an SPDX
license identifier.  The chosen identifier is 'GPL-2.0 WITH
Linux-syscall-note' which is the officially assigned identifier for the
Linux syscall exception.  SPDX license identifiers are a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.  See the previous patch in this series for the
methodology of how this patch was researched.

f82b77462b 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 $m | grep '^MADV_' > /dev/null 2>&1
     then
       grep -h '#define[ \t]*'$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

f3539c12d8 tools include: Add uapi mman.h for each architecture 
Some mmap related macros have different values for different
architectures. This patch introduces uapi mman.h for each
architectures.

Three headers are cloned from kernel include to tools/include:

 tools/include/uapi/asm-generic/mman-common.h
 tools/include/uapi/asm-generic/mman.h
 tools/include/uapi/linux/mman.h

The main part of this patch is generated by following script:

 macros=`cat $0 | awk 'V==1 {print}; /^# start macro list/ {V=1}'`
 for arch in `ls tools/arch`
 do
   [ -d tools/arch/$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
   guard="TOOLS_ARCH_"`echo $arch | awk '{print toupper($0)}'`_UAPI_ASM_MMAN_FIX_H
   echo '#ifndef '$guard > $target
   echo '#define '$guard >> $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
   echo '#endif' >> $target
   echo "$target"
 done
