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.

Both new HWCAPs were introduced in these kernel commits:
- 7e8403ecaf884f307b627f3c371475913dd29292
"s390: add HWCAP_S390_PCI_MIO to ELF hwcaps"
- 7e82523f2583e9813e4109df3656707162541297
"s390/hwcaps: make sie capability regular hwcap"
Also note that the kernel commit 511ad531afd4090625def4d9aba1f5227bd44b8e
"s390/hwcaps: shorten HWCAP defines" has shortened the prefix of the macros
from "HWCAP_S390_" to "HWCAP_". For compatibility reasons, we do not
change the prefix in public glibc header file.

We stopped adding "Contributed by" or similar lines in sources in 2012
in favour of git logs and keeping the Contributors section of the
glibc manual up to date. Removing these lines makes the license
header a bit more consistent across files and also removes the
possibility of error in attribution when license blocks or files are
copied across since the contributed-by lines don't actually reflect
reality in those cases.
Move all "Contributed by" and similar lines (Written by, Test by,
etc.) into a new file CONTRIBUTED-BY to retain record of these
contributions. These contributors are also mentioned in
manual/contrib.texi, so we just maintain this additional record as a
courtesy to the earlier developers.
The following scripts were used to filter a list of files to edit in
place and to clean up the CONTRIBUTED-BY file respectively. These
were not added to the glibc sources because they're not expected to be
of any use in future given that this is a one time task:

Unfortunately some HWCAP names like HWCAP_S390_VX differs between
kernel (see <kernel>/arch/s390/include/asm/elf.h) and glibc.
Therefore, those HWCAP names from kernel are now introduced as alias

Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:

The new hwcap values indicate support for:
-"Vector-Enhancements Facility 2" (tag "vxe2", hwcap 2^15)
-"Vector-Packed-Decimal-Enhancement Facility" (tag "vxp", hwcap 2^16)
-"Enhanced-Sort Facility" (tag "sort", hwcap 2^17)
-"Deflate-Conversion Facility" (tag "dflt", hwcap 2^18)
The vxe2 hwcap is also marked as important hwcap.
ChangeLog:
* sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags):
Add vxe2, vxp, dflt, sort flags.
* sysdeps/s390/dl-procinfo.h: Add HWCAP_S390_VXRS_EXT2,
HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT, HWCAP_S390_DFLT
capabilities.
(HWCAP_IMPORTANT): Add HWCAP_S390_VXRS_EXT2.
* sysdeps/unix/sysv/linux/s390/bits/hwcap.h
(HWCAP_S390_VXRS_EXT2, HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT,
HWCAP_S390_DFLT): Define.

This patch adds vx and vxe as important hwcaps
which allows one to provide shared libraries
tuned for platforms with non-vx/-vxe, vx or vxe.

Add HWCAP_S390_VX and HWCAP_S390_VXE.

The new hwcap values indicate support for:
- Vector packed decimal facility
- Vector enhancements facility 1
- Guarded storage facility
Note: arch12 is NOT the official name of the new CPU.
It refers to the edition number of the Principle of Operations manual.
ChangeLog:
* sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags):
Add vxd, vxe, gs flag.
* sysdeps/s390/dl-procinfo.h: Add HWCAP_S390_VXD, HWCAP_S390_VXE,
HWCAP_S390_GS capability.
* sysdeps/unix/sysv/linux/s390/bits/hwcap.h
(HWCAP_S390_VXD, HWCAP_S390_VXE, HWCAP_S390_GS): Define.

The new IBM z13 is added to platform string array.
The macro _DL_PLATFORMS_COUNT is incremented to 8,
because it was not incremented by commit
"S/390: Sync AUXV capabilities and archs with kernel".
ChangeLog:
* sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags): Add z13.
* sysdeps/s390/dl-procinfo.h (_DL_PLATFORMS_COUNT): Increased.

The HWCAP_S390_VX flag in hwcap field of auxiliary vector indicates
if the vector facility is available and the kernel is aware of it.
This can be tested with LD_SHOW_AUXV=1 <prog>.
Currently it does not show te, because it was not incremented
by commit "S/390: Add hwcap value for transactional execution.".
Thus _DL_HWCAP_COUNT is incremented by two.
ChangeLog:
* sysdeps/s390/dl-procinfo.c (_dl_s390_platforms): Add vector flag.
* sysdeps/s390/dl-procinfo.h: Add vector capability.
* sysdeps/unix/sysv/linux/s390/bits/hwcap.h (HWCAP_S390_VX): Define.
