2b778ceb40 Update copyright dates with scripts/update-copyrights 
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 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...
remote: *** error: lines with trailing whitespace found
remote: error: hook declined to update refs/heads/master

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

f3dcae82d5 Save and restore vector registers in x86-64 ld.so 
This patch adds SSE, AVX and AVX512 versions of _dl_runtime_resolve
and _dl_runtime_profile, which save and restore the first 8 vector
registers used for parameter passing.  elf_machine_runtime_setup
selects the proper _dl_runtime_resolve or _dl_runtime_profile based
on _dl_x86_cpu_features.  It avoids race condition caused by
FOREIGN_CALL macros, which are only used for x86-64.

Performance impact of saving and restoring 8 vector registers are
negligible on Nehalem, Sandy Bridge, Ivy Bridge and Haswell when
ld.so is optimized with SSE2.

	[BZ #15128]
	* sysdeps/x86_64/Makefile [$(subdir) == elf] (tests): Add
	ifuncmain8.
	(modules-names): Add ifuncmod8.
	($(objpfx)ifuncmain8): New rule.
	* sysdeps/x86_64/dl-machine.h: Include <dl-procinfo.h> and
	<cpuid.h>.
	(elf_machine_runtime_setup): Use _dl_runtime_resolve_sse,
	_dl_runtime_resolve_avx, or _dl_runtime_resolve_avx512,
	_dl_runtime_profile_sse, _dl_runtime_profile_avx, or
	_dl_runtime_profile_avx512, based on HAS_ARCH_FEATURE.
	* sysdeps/x86_64/dl-trampoline.S: Rewrite.
	* sysdeps/x86_64/dl-trampoline.h: Likewise.
	* sysdeps/x86_64/ifuncmain8.c: New file.
	* sysdeps/x86_64/ifuncmod8.c: Likewise.
	* sysdeps/x86_64/nptl/tcb-offsets.sym (RTLD_SAVESPACE_SSE):
	Removed.
	* sysdeps/x86_64/nptl/tls.h (__128bits): Removed.
	(tcbhead_t): Change rtld_must_xmm_save to __glibc_unused1.
	Change rtld_savespace_sse to __glibc_unused2.
	(RTLD_CHECK_FOREIGN_CALL): Removed.
	(RTLD_ENABLE_FOREIGN_CALL): Likewise.
	(RTLD_PREPARE_FOREIGN_CALL): Likewise.
	(RTLD_FINALIZE_FOREIGN_CALL): Likewise.
