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.

This patch adds new AArch64 HWCAPs from Linux 5.0 to the AArch64
bits/hwcap.h and dl-procinfo.c.
Tested (compilation only) with build-many-glibcs.py for
aarch64-linux-gnu.
* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_SB): New
macro.
(HWCAP_PACA): Likewise.
(HWCAP_PACG): Likewise.
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT):
Increase to 32.
(_dl_aarch64_cap_flags): Add new entries for new HWCAPs.
bits/hwcap.h should be updated together with dl-procinfo.c.
* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h: Add comment.
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT):
Update.
Linux 4.17 adds four new AArch64 hwcap values. This patch adds them
to glibc's AArch64 bits/hwcap.h, with corresponding dl-procinfo.c
updates.
Tested with build-many-glibcs.py for aarch64.
* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_DIT): New
macro.
(HWCAP_USCAT): Likewise.
(HWCAP_ILRCPC): Likewise.
(HWCAP_FLAGM): Likewise.
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT):
Increase to 28.
(_dl_aarch64_cap_flags): Add new flag names.
This patch updates the aarch64 bits/hwcap.h and dl-procinfo.c for the
new HWCAP_ASIMDFHM value in Linux 4.16.
Tested with build-many-glibcs.py for aarch64-linux-gnu.
* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_ASIMDFHM):
New macro.
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT):
Increase to 24.
(_dl_aarch64_cap_flags): Add asimdfhm.
Define new HWCAP bits and add their name to dl-procinfo.c following
the linux definitions. Synchronizing with v4.15-rc8 version of linux,
these are not expected to change before the 4.15 release.
* sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_SHA3): Define.
(HWCAP_SM3, HWCAP_SM4, HWCAP_ASIMDDP, HWCAP_SHA512, HWCAP_SVE): Define.
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c
(_dl_aarch64_cap_flags): Update.
(_DL_HWCAP_COUNT): Update.
Remove unused _DL_HWCAP_LAST definition and move _DL_HWCAP_COUNT
where it is needed (dl-procinfo.h always includes dl-procinfo.c).
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.h
(_DL_HWCAP_LAST): Remove.
(_DL_HWCAP_COUNT): Move to ...
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c
(_DL_HWCAP_COUNT): ... here.
Add support for routines in dl-procinfo.h to show string versions of
HWCAP entries when a program is invoked with the LD_SHOW_AUXV
environment variable set and also to aid in path resolution for
ldconfig.
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c
(_dl_aarch64_cap_flags): New array.
* sysdeps/unix/sysv/linux/aarch64/dl-procinfo.h
(_dl_hwcap_string, _dl_string_hwcap, _dl_procinfo): Implement
functions.
