5a82c74822 Prefer https to http for gnu.org and fsf.org URLs 
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:

sed -ri '
  s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
  s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g
' \
  $(find $(git ls-files) -prune -type f \
      ! -name '*.po' \

      ! '(' -name preconfigure \
            -execdir test -f preconfigure.ac ';' ')' \
      -print)

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

  chmod a+x sysdeps/unix/sysv/linux/riscv/configure
  # Omit irrelevant whitespace and comment-only changes,
  # perhaps from a slightly-different Autoconf version.
  git checkout -f \
    sysdeps/csky/configure \
    sysdeps/hppa/configure \
    sysdeps/riscv/configure \
    sysdeps/unix/sysv/linux/csky/configure
  # Omit changes that caused a pre-commit check to fail like this:
  # remote: *** error: sysdeps/powerpc/powerpc64/ppc-mcount.S: trailing lines
  git checkout -f \
    sysdeps/powerpc/powerpc64/ppc-mcount.S \
    sysdeps/unix/sysv/linux/s390/s390-64/syscall.S
  # Omit change that caused a pre-commit check to fail like this:

  git checkout -f sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S

421749d693 S390: Add arch13 memmem ifunc variant. 
This patch introduces the new arch13 ifunc variant for memmem.
For needles longer than 9 bytes it is relying on the common-code
implementation.  For shorter needles it is using the new vstrs instruction
which is able to search a substring within a vector register.

ChangeLog:

	* sysdeps/s390/Makefile (sysdep_routines): Add memmem-arch13.
	* sysdeps/s390/ifunc-memmem.h (HAVE_MEMMEM_ARCH13, MEMMEM_ARCH13,
	MEMMEM_Z13_ONLY_USED_AS_FALLBACK, HAVE_MEMMEM_IFUNC_AND_ARCH13_SUPPORT):
	New defines.
	* sysdeps/s390/memmem-arch13.S: New file.
	* sysdeps/s390/memmem-vx.c: Omit GI symbol for z13 memmem ifunc variant
	if it is only used as fallback.
	* sysdeps/s390/memmem.c (memmem): Add arch13 variant in ifunc selector.
	* sysdeps/s390/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Add ifunc variant for arch13 memmem.
