Update.
* posix/sched.h: Change prototypes of sched_getaffinity and
sched_setaffinity. Define CPU_SET, CPU_CLR, CPU_ISSET, and CPU_ZERO.
* sysdeps/generic/sched_getaffinity.c: Adjust definition.
* sysdeps/generic/sched_setaffinity.c: Likewise.
* sysdeps/generic/bits/sched.h: Define __CPU_SETSIZE, __NCPUBITS,
__CPUELT, __CPUMASK, cpu_set_t, __cpu_mask, __CPU_ZERO, __CPU_SET,
__CPU_CLR, and __CPU_ISSET.
* sysdeps/unix/sysv/linux/bits/sched.h: Likewise.
* sysdeps/unix/sysv/linux/sched_getaffinity.c: New file.
* sysdeps/unix/sysv/linux/sched_setaffinity.c: New file.
* include/atomic.h (atomic_exchange_acq): Renamed from atomic_exchange.
(atomic_exchange_rel): New #define.
* sysdeps/ia64/bits/atomic.h: Likewise.
* sysdeps/i386/i486/bits/atomic.h (atomic_exchange_acq): Renamed from
atomic_exchange.
* sysdeps/m68k/m68020/bits/atomic.h: Likewise.
* sysdeps/powerpc/bits/atomic.h: Likewise.
* sysdeps/sparc/sparc32/sparcv9/bits/atomic.h: Likewise.
* sysdeps/sparc/sparc64/bits/atomic.h: Likewise.
* sysdeps/x86_64/bits/atomic.h: Likewise.
* csu/tst-atomic.c: Use atomic_exchange_acq instead of atomic_exchange.
