This patch updates the kernel version in the test tst-mman-consts.py
to 5.16. (There are no new MAP_* constants covered by this test in
5.16 that need any other header changes.)
Tested with build-many-glibcs.py.
I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

The new tables are currently only used for consistency checks
with the installed kernel headers and the architecture-independent
system call names table. They are based on Linux 5.4.
The goal is to use these architecture-specific tables to ensure
that system call wrappers are available irrespective of the version
of the installed kernel headers.
The tables are formatted in the form of C header files so that they
can be used directly in an #include directive, without external
preprocessing. (External preprocessing of a plain table file
would introduce cross-subdirectory dependency issues.) However,
the intent is that they can still be treated as tables and can be
processed by simple tools.
The irregular system call names on 32-bit arm add a complication.
The <fixup-asm-unistd.h> header is introduced to work around that,
and the system calls are listed under regular names in the
<arch-syscall.h> file.
A make target, update-syscalls-list, is added to patch the glibc
sources with data from the current kernel headers.

The Linux 5.3 uapi headers have some rearrangement relating to MAP_*
constants, which includes the effect of adding definitions of MAP_SYNC
on powerpc and sparc. This patch updates the corresponding glibc
bits/mman.h headers accordingly, and updates the Linux kernel version
number in tst-mman-consts.py to reflect that these constants are now
current with that kernel version.
Tested with build-many-glibcs.py.
* sysdeps/unix/sysv/linux/powerpc/bits/mman.h [__USE_MISC]
(MAP_SYNC): New macro.
* sysdeps/unix/sysv/linux/sparc/bits/mman.h [__USE_MISC]
(MAP_SYNC): Likewise.
* sysdeps/unix/sysv/linux/tst-mman-consts.py (main): Update Linux
kernel version number to 5.3.
The tst-mman-consts.py test includes a kernel version number, to avoid
failures because of newly added constants in the kernel (if kernel
headers are newer than this version of glibc) or missing constants in
the kernel (if kernel headers are older than this version of glibc).
This patch updates it to 5.2 to reflect that the MAP_* constants in
glibc are still current as of that kernel version.
Tested with build-many-glibcs.py.
* sysdeps/unix/sysv/linux/tst-mman-consts.py (main): Update Linux
kernel version number to 5.2.
This patch updates the Linux kernel version in tst-mman-consts.py to
4.20 (meaning that's the version for which glibc is expected to have
the same constants as the kernel, up to the exceptions listed in the
test). (Once we have more such tests sharing common infrastructure, I
expect the kernel version will be something set in the infrastructure
shared by all such tests, rather than something needing updating
separately for each test for each new kernel version.)
Tested with build-many-glibcs.py.
* sysdeps/unix/sysv/linux/tst-mman-consts.py (main): Expect
constants to match with Linux 4.20.
Continuing the process of building up and using Python infrastructure
for extracting and using values in headers, this patch adds a test
that MAP_* constants from sys/mman.h agree with those in the Linux
kernel headers. (Other sys/mman.h constants could be added to the
test separately.)
This set of constants has grown over time, so the generic code is
enhanced to allow saying extra constants are OK on either side of the
comparison (where the caller sets those parameters based on the Linux
kernel headers version, compared with the version the headers were
last updated from). Although the test is a custom Python file, my
intention is to move in future to a single Python script for such
tests and text files it takes as inputs, once there are enough
examples to provide a guide to the common cases in such tests (I'd
like to end up with most or all such sets of constants copied from
kernel headers having such tests, and likewise for structure layouts
from the kernel).
The Makefile code is essentially the same as for tst-signal-numbers,
but I didn't try to find an object file to depend on to represent the
dependency on the headers used by the test (the conform/ tests don't
try to represent such header dependencies at all, for example).
Tested with build-many-glibcs.py, and also for x86_64 with older
kernel headers.
* scripts/glibcextract.py (compare_macro_consts): Take parameters
to allow extra macros from first or second sources.
* sysdeps/unix/sysv/linux/tst-mman-consts.py: New file.
