This enables stfle.155 and adds the subfunctions for KDSA. Bit 155 is
added to the list of facilities that will be enabled when there is no
cpu model involved as MSA9 requires no additional handling from
userspace, e.g. for migration.
Please note that a cpu model enabled user space can and will have the

With 720f228e8d ("bpf: fix broken BPF selftest build") the
inclusion of arch-specific header files changed. Including the
asm/bpf_perf_event.h on s390, correctly includes the s390 specific

asm/ptrace.h and the build fails with:

This is caused by a recent update to the s390 asm/ptrace.h file
that is not (yet) available in the local installation. That means,
the s390 asm/ptrace.h must be included from the tools/arch/s390
directory.
Because there is no proper framework to deal with asm specific
includes in tools/, slightly modify the s390 asm/bpf_perf_event.h
to include the local ptrace.h header file.
See also discussion on
https://marc.info/?l=linux-s390&m=151359424420691&w=2
Please note that this needs to be preserved until tools/ is able to
correctly handle asm specific headers.

Long ago we decided to be verbotten including files in the kernel git
sources from tools/ living source code, to avoid disturbing kernel
development (and perf's and other tools/) when, say, a kernel hacker
adds something, tests everything but tools/ and have tools/ build
broken.
This got broken recently by s/390, fix it by copying
arch/s390/include/uapi/asm/perf_regs.h to tools/arch/s390/include/uapi/asm/,
making this one be used by means of <asm/perf_regs.h> and updating
tools/perf/check_headers.sh to make sure we are notified when the
original changes, so that we can check if anything is needed on the
tooling side.
This would have been caught by the 'tarkpg' test entry in:
$ make -C tools/perf build-test
When run on a s/390 build system or container.

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.

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

otherwise syscall usage would not be possible.

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
exit 0
