Stefan Liebler c813dae5d8 S390: Use C11-like atomics instead of plain memory accesses in lock elision code. ... This uses atomic operations to access lock elision metadata that is accessed concurrently (ie, adapt_count fields). The size of the data is less than a word but accessed only with atomic loads and stores. See also x86 commit ca6e601a9d: "Use C11-like atomics instead of plain memory accesses in x86 lock elision." ChangeLog: * sysdeps/unix/sysv/linux/s390/elision-lock.c (__lll_lock_elision): Use atomics to load / store adapt_count. * sysdeps/unix/sysv/linux/s390/elision-trylock.c (__lll_trylock_elision): Likewise.		2016-12-20 15:12:48 +01:00
