lib/libc/thread: rthread.c
Log message:
Add memory barriers to libc's _spinlock() to make the mechanism
serialize memory accesses properly.
_spinlock()'s backend, _atomic_lock(), already issues an entry barrier
on some architectures, but that practice has not been consistent. This
patch generalizes the barrier use.
