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*' \
      ! -path COPYING ! -path COPYING.LIB \
      ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \
      ! -path manual/texinfo.tex ! -path scripts/config.guess \
      ! -path scripts/config.sub ! -path scripts/install-sh \
      ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \
      ! -path INSTALL ! -path  locale/programs/charmap-kw.h \
      ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \
      ! '(' -name configure \
            -execdir test -f configure.ac -o -f configure.in ';' ')' \
      ! '(' -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:
  # remote: *** error: sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S: last line does not end in newline
  git checkout -f sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S

1b6e07f8e0 sparc: M7 optimized memcpy/mempcpy/memmove 
Support added to identify Sparc M7/T7/S7/M8/T8 processor capability.
Performance tests run on Sparc S7 using new code and old niagara4 code.

Optimizations for memcpy also apply to mempcpy and memmove
where they share code. Optimizations for memset also apply
to bzero as they share code.

For memcpy/mempcpy/memmove, performance comparison with niagara4 code:
Long word aligned data
  0-127 bytes - minimal changes
  128-1023 bytes - 7-30% gain
  1024+ bytes - 1-7% gain (in cache); 30-100% gain (out of cache)
Word aligned data
  0-127 bytes - 50%+ gain
  128-1023 bytes - 10-200% gain
  1024+ bytes - 0-15% gain (in cache); 5-50% gain (out of cache)
Unaligned data
  0-127 bytes - 0-70%+ gain
  128-447 bytes - 40-80%+ gain
  448-511 bytes - 1-3% loss
  512-4096 bytes - 2-3% gain (in cache); 0-20% gain (out of cache)
  4096+ bytes - ± 3% (in cache); 20-50% gain (out of cache)

Tested in sparcv9-*-* and sparc64-*-* targets in both multi and
non-multi arch configurations.

88684de7a6 sparc: Implement memcpy/mempcpy ifunc selection in C 
This patch refactor the SPARC64 ifunc selector to a C implementation.
The x86_64 implementation is used as default, which resulted in common
definitions (ifunc-init.h) used on both architectures.  No functional
change is expected, including ifunc resolution rules.

Checked on sparc64-linux-gnu, sparcv9-linux-gnu and x86_64-linux-gnu.

	* sysdeps/sparc/sparc32/sparcv9/multiarch/memcpy-ultra1.S: New
	file.
	* sysdeps/sparc/sparc32/sparcv9/multiarch/memcpy.c: Likewise.
	* sysdeps/sparc/sparc32/sparcv9/multiarch/mempcpy.c: Likewise.
	* sysdeps/sparc/sparc64/multiarch/ifunc-memcpy.h: Likewise.

	* sysdeps/sparc/sparc64/multiarch/Makefile [$(subdir) = string]
	(sysdep_routines): Add memcpy-ultra1.
	* sysdeps/sparc/sparc64/multiarch/memcpy.S: Remove file.
