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.

07ed18d26a Add elision tunables 
This patch adds several new tunables to control the behavior of
elision on supported platforms[1].   Since elision now depends
on tunables, we should always *compile* with elision enabled,
and leave the code disabled, but available for runtime
selection.  This gives us *much* better compile-time testing of
the existing code to avoid bit-rot[2].

Tested on ppc, ppc64, ppc64le, s390x and x86_64.

[1] This part of the patch was initially proposed by
Paul Murphy but was "staled" because the framework have changed
since the patch was originally proposed:

https://patchwork.sourceware.org/patch/10342/

[2] This part of the patch was inititally proposed as a RFC by
Carlos O'Donnell.  Make sense to me integrate this on the patch:

https://sourceware.org/ml/libc-alpha/2017-05/msg00335.html

	* elf/dl-tunables.list: Add elision parameters.
	* manual/tunables.texi: Add entries about elision tunable.
	* sysdeps/unix/sysv/linux/powerpc/elision-conf.c:
	Add callback functions to dynamically enable/disable elision.

	* nptl/Makefile:
	Disable elision so it can verify error case for destroying a mutex.
	* sysdeps/powerpc/nptl/elide.h:

dd037fb3df S390: Optimize lock-elision by decrementing adapt_count at unlock. 
This patch decrements the adapt_count while unlocking the futex
instead of before aquiring the futex as it is done on power, too.
Furthermore a transaction is only started if the futex is currently free.
This check is done after starting the transaction, too.
If the futex is not free and the transaction nesting depth is one,
we can simply end the started transaction instead of aborting it.
The implementation of this check was faulty as it always ended the
started transaction.  By using the fallback path, the the outermost
transaction was aborted.  Now the outermost transaction is aborted
directly.

This patch also adds some commentary and aligns the code in
elision-trylock.c to the code in elision-lock.c as possible.

ChangeLog:

	* sysdeps/unix/sysv/linux/s390/lowlevellock.h
	(__lll_unlock_elision, lll_unlock_elision): Add adapt_count argument.
	* sysdeps/unix/sysv/linux/s390/elision-lock.c:
