*	powerpc: Add adaptive elision to rwlocks	Adhemerval Zanella	2015-01-12	1	-0/+3
\| \| \| \| \| \|	This patch adds support for lock elision using ISA 2.07 hardware transactional memory for rwlocks. The logic is similar to the one presented in pthread_mutex lock elision.
*	powerpc: Add the lock elision using HTM	Adhemerval Zanella	2015-01-12	1	-0/+80
	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.
