Addition of flush operations

Here's another possible solution. It works for a compare-and-swap instruction
bypasses cache and does not take into account the cache content. In such case,
we need to flush the cache line after store in the lock variable.

It would be better if we had a _CPU_read_uncached_int() type of function.
