Uros Bizjak e73c4e34a0 locking/atomic/x86: Introduce arch_atomic64_read_nonatomic() to x86_32 ...

Introduce arch_atomic64_read_nonatomic() for 32-bit targets to load
the value from atomic64_t location in a non-atomic way. This
function is intended to be used in cases where a subsequent atomic
operation will handle the torn value, and can be used to prime the
first iteration of unconditional try_cmpxchg() loops.
