powerpc: Revert to default atomic ops in elision code
Power ISA 2.07B section B.5.5 relaxed the barrier requirement around a TLE enabled lock. It is now identical to a traditional lock. 2015-08-26 Paul E. Murphy <murphyp@linux.vnet.ibm.com> * sysdeps/unix/sysv/linux/powerpc/elision-lock.c (__arch_compare_and_exchange_val_32_acq): Remove and use common definition. ISA 2.07B no longer requires full sync.
