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 \

      ! '(' -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

59213094c8 nptl: Rename lll_timedlock to lll_clocklock and add clockid parameter 
Rename lll_timedlock to lll_clocklock and add clockid
parameter to indicate the clock that the abstime parameter should
be measured against in preparation for adding
pthread_mutex_clocklock.

The name change mirrors the naming for the exposed pthread functions:

 timed => absolute timeout measured against CLOCK_REALTIME (or clock
          specified by attribute in the case of pthread_cond_timedwait.)

 clock => absolute timeout measured against clock specified in preceding
          parameter.

	* sysdeps/nptl/lowlevellock.h (lll_clocklock): Rename from
	lll_timedlock and add clockid parameter. (__lll_clocklock): Rename
	from __lll_timedlock and add clockid parameter.
	* sysdeps/unix/sysv/linux/sparc/lowlevellock.h (lll_clocklock):
	Likewise.
	* nptl/lll_timedlock_wait.c (__lll_clocklock_wait): Rename from
	__lll_timedlock_wait and add clockid parameter. Use __clock_gettime
	rather than __gettimeofday so that clockid can be used. This means
	that conversion from struct timeval is no longer required.
	* sysdeps/sparc/sparc32/lowlevellock.c (lll_clocklock_wait):
	Likewise.
	* sysdeps/sparc/sparc32/lll_timedlock_wait.c: Update comment to
	refer to __lll_clocklock_wait rather than __lll_timedlock_wait.
	* nptl/pthread_mutex_timedlock.c (lll_clocklock_elision): Rename
	from lll_timedlock_elision, add clockid parameter and use
	meaningful names for other parameters. (__pthread_mutex_timedlock):
	Pass CLOCK_REALTIME where necessary to lll_clocklock and
	lll_clocklock_elision.
	* sysdeps/unix/sysv/linux/powerpc/lowlevellock.h
	(lll_clocklock_elision): Rename from lll_timedlock_elision and add
	clockid parameter. (__lll_clocklock_elision): Rename from
	__lll_timedlock_elision and add clockid parameter.
	* sysdeps/unix/sysv/linux/s390/lowlevellock.h: Likewise.
	* sysdeps/unix/sysv/linux/x86/lowlevellock.h: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/elision-timed.c
	(__lll_lock_elision): Call __lll_clocklock_elision rather than
	__lll_timedlock_elision. (EXTRAARG): Add clockid parameter.
	(LLL_LOCK): Likewise.
	* sysdeps/unix/sysv/linux/s390/elision-timed.c: Likewise.
	* sysdeps/unix/sysv/linux/x86/elision-timed.c: Likewise.

8d2c0a593b powerpc: Add the lock elision using HTM 
This patch adds support for lock elision using ISA 2.07 hardware
transactional memory instructions for pthread_mutex primitives.
Similar to s390 version, the for elision logic defined in
'force-elision.h' is only enabled if ENABLE_LOCK_ELISION is defined.

Also, the lock elision code should be able to be built even with
a compiler that does not provide HTM support with builtins.
However I have noted the performance is sub-optimal due scheduling
pressures.
