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.

As described in BZ#22457 an interpose malloc can free an invalid
pointer for fallback preadv implementation. Fortunately this is
just and issue on microblaze-linux-gnu running kernels older than
3.15. This patch fixes it by calling mmap/unmap instead of
posix_memalign/ free.
Checked on microblaze-linux-gnu check with run-built-tests=no and
by using the sysdeps/posix implementation on x86_64-linux-gnu (just
for sanity test where it shown no regression).
[BZ #22457]
* sysdeps/posix/preadv_common.c (PREADV): Use mmap/munmap instead of
posix_memalign/free.
* sysdeps/posix/pwritev_common.c (PWRITEV): Likewise.
Currently all architectures but microblaze use wire-up syscall for
p{readv,write}v. Microblaze still uses the syscall emulation using
sysdep/posix/p{readv,writev}.c and it was reported in some ocasions
[1] [2] that it might have some issues with some linux specific
usage (mainly with O_DIRECT and the alignment requirement).
Although it is not an issue for virtually all the system, this
patch refactors the sysdeps/posix p{read,write}v syscall to avoid
such issue (by using posix_memalign on the buffer used on
p{read,write} call) and by refactoring it common files to avoid
the need check on defines to correct set the alias and internal
symbols.
Checked on microblaze-linux-gnu check with run-built-tests=no and
by using the sysdeps/posix implementation on x86_64-linux-gnu (just
for sanity test where it shown no regression).
* sysdeps/posix/preadv.c: Use sysdeps/posix/preadv_common.c.
* sysdeps/posix/preadv64.c: Likewise.
* sysdeps/unix/sysv/linux/preadv.c: Likewise.
* sysdeps/unix/sysv/linux/preadv64.c: Likewise.
* sysdeps/posix/pwritev.c: Use sysdeps/posix/pwritev_common.c.
* sysdeps/posix/pwritev64.c: Likewise.
* sysdeps/unix/sysv/linux/pwritev.c: Likewise.
* sysdeps/unix/sysv/linux/pwritev64.c: Likewise.
* sysdeps/posix/preadv_common.c: New file.
