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 'ChangeLog*' \

      ! '(' -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:

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.

	STRSTR_Z13_ONLY_USED_AS_FALLBACK, HAVE_STRSTR_IFUNC_AND_ARCH13_SUPPORT):

96fbb9a328 S390: Add arch13 memmove ifunc variant. 
This patch introduces the new arch13 ifunc variant for memmove.
For the forward or non-overlapping case it is just using memcpy.
For the backward case it relies on the new instruction mvcrl.
The instruction copies up to 256 bytes at once.
In case of an overlap, it copies the bytes like copying them
one by one starting from right to left.

ChangeLog:

	* sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_ARCH13, MEMMOVE_ARCH13
	HAVE_MEMMOVE_IFUNC_AND_ARCH13_SUPPORT): New defines.
	* sysdeps/s390/memcpy-z900.S: Add arch13 memmove implementation.
	* sysdeps/s390/memmove.c (memmove): Add arch13 variant in
	ifunc selector.
	* sysdeps/s390/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Add ifunc variant for arch13 memmove.
	* sysdeps/s390/multiarch/ifunc-resolve.h (S390_STFLE_BITS_ARCH13_MIE3,
	S390_IS_ARCH13_MIE3): New defines.

8e5a0afbbf S390: Refactor strcat ifunc handling. 
The ifunc handling for strcat is adjusted in order to omit ifunc

cdd927d98c S390: Add z13 memmove ifunc variant. 
This patch introduces a z13 specific ifunc variant for memmove.
As the common code implementation, it checks if we can copy from
the beginning to the end - with z196 memcpy implementation - or
if we have to copy from the end to the beginning.
The latter case is done by using vector load/store instructions.

If vector instructions are not available, the common-code is
used as fallback.  Therefore it is implemented in memmove-c with
a different name.
Furthermore the ifunc logic decides if we need the common-code
implementation at all.  If vector instructions are supported
due to the minimum architecture level set we can skip the
common-code ifunc variant.

ChangeLog:

	* sysdeps/s390/Makefile (sysdep_routines): Add memmove-c.
	* sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_IFUNC,
	HAVE_MEMMOVE_IFUNC_AND_VX_SUPPORT, MEMMOVE_DEFAULT,

18eb862d45 S390: Refactor memcpy/mempcpy ifunc handling. 
This patch moves all ifunc variants for memcpy/mempcpy
to sysdeps/s390/memcpy-z900.S. The configure-check/preprocessor logic
in sysdeps/s390/ifunc-memcpy.h decides if ifunc is needed at all
and which ifunc variants should be available.
E.g. if the compiler/assembler already supports z196 by default,
the older ifunc variants are not included.
If we only need the newest ifunc variant,
then we can skip ifunc at all.

Therefore the ifunc-resolvers and __libc_ifunc_impl_list are adjusted
in order to handle only the available ifunc variants.

	* sysdeps/s390/ifunc-memcpy.h: New File.
