2017-11-02License cleanup: add SPDX license identifier to uapi header files with a licenseGreg Kroah-Hartman2-0/+2
Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: 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". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. 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.

2017-11-02License cleanup: add SPDX license identifier to uapi header files with no ↵Greg Kroah-Hartman2-0/+2
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.

2016-09-19tools include: Add mman macros needed by perf for all archWang Nan1-0/+2
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 > $real_target echo '#define '$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 exit 0 # Following macros are extracted from: # tools/perf/trace/beauty/mmap.c # # start macro list MADV_DODUMP MADV_DOFORK MADV_DONTDUMP MADV_DONTFORK MADV_DONTNEED MADV_FREE MADV_HUGEPAGE MADV_HWPOISON MADV_MERGEABLE MADV_NOHUGEPAGE MADV_NORMAL MADV_RANDOM MADV_REMOVE MADV_SEQUENTIAL MADV_SOFT_OFFLINE MADV_UNMERGEABLE MADV_WILLNEED MAP_32BIT MAP_ANONYMOUS MAP_DENYWRITE MAP_EXECUTABLE MAP_FILE MAP_FIXED MAP_GROWSDOWN MAP_HUGETLB MAP_LOCKED MAP_NONBLOCK MAP_NORESERVE MAP_POPULATE MAP_PRIVATE MAP_SHARED MAP_STACK MAP_UNINITIALIZED MREMAP_FIXED MREMAP_MAYMOVE PROT_EXEC PROT_GROWSDOWN PROT_GROWSUP PROT_NONE PROT_READ PROT_SEM PROT_WRITE Signed-off-by: Wang Nan <wangnan0@huawei.com> Tested-by: Kim Phillips <kim.phillips@arm.com> Tested-by: Naveen N.
